SPDM

New FIRMWARE 2.7

Preliminary remarks Today, the standard firmware installed in the SPDM is the 2.6 enhanced version with Profibus-DP protocol inside (the Profibus DP board is delivered as option kit “SPPB2”). This firmware doesn’t support the PC tool program “WZSPD”, than we cannot have PC tool and Profibus-DP communication at the same time in one control board. The “Centronic” printers today are not available in the market, so it’s not possible to print the following data: DRIVE TRACE THYRISTOR TRACE CONFIGURATION PARAMETERS To remove the above problems we have developed the new release 2.7.

New 2.7 firmware release allows: A) B) C)

PC Tool and Profibus-DP communication at the same time. Data print ( by PC ). New functions.

New functions: 1.

Emergency ramp. It will be possible to define a ramp with settable time on the emergency stop (TH3=TacRF, TH4=TdcRF).

“Bump less” function. It’s possible to restart a motor runnig with the same reference of the actual speed (only with the ramp enable). In the previous releases the speed reference started from zero: this generated dangerous hard braking torque for 4-quadrant operation SPDM.

Speed reference adding term: now it can be added downstream ramp also (CFA=NoADVR=ON/OFF).

Torque proof: the user can manage completely the mechanical brake with a digital output (D01÷D07).

Disabling of the regenerative braking: the user can disable the regenerative braking when the armature voltage level becomes greater than a programmable threshold. CEC = Dis Reg = ON/OFF CE2 = Armature voltage threshold level. This function is helpful to avoid burning of fuses, when is not possible to maintain the right margin between the power supply voltage and the armature voltage level (for example with low Rsc ratio, or net with negative voltage variations greater than 10%).

Speed visualisation: the user can configure one of the auxiliary variable Aux1-2-3 (with parameters DG5-DG6-DG7) as “Encod” to display the Encoder speed (it is possible even if tachometer speed feedback is used).

PC-tool: there is a new parameter to enable the communication with the PC (DED = PC_Com = OFF/ON)

Digital Output configuration: the user can configure one of digital outputs (parameters DO1÷DO6) as “ParSet“ to display the active parameters set.

TENSION regulators: the new parameter CN6 sets the delay of the diameter calculation in relation to the tension regulator start command (COM3).

10.

Double set of parameters: there is a new parameter (CDG) to enable/disable the switch of the parameters sets.

11.

Profibus-DP: digital outputs OUT1÷OUT6 can be driven directly writing bits 8÷13 of the command word (parameters DO1÷DO6 must be set to “Profib”). Also “reset command” is performed writing bit 7 of the command word.

Firmware 2.7

NOTE: To implement these new functionalities, we have removed some functions rarely used in our applications. Follow the list of these functions:

Selection of the armature current reference from the Rif differential analog input (CA1= RifC12). It is no more possible to set the armature current reference origin (CA1= RifC12) from the analog input RIF (terminals XM1-33, 34) with sign coming of the logic inputs state COM1 e COM2.

Current limit linear recalibration as function of the speed: The recalibration tooks place from the speed set by the parameter DB7 to the maximum speed. (No more from the parameter CE8, that is removed).

Maximum speed limited to the base speed value. If it is enabled the switching from speed feedback to armature voltage feedback when the tacho loss protection occurs (CBG = ON), the maximum speed with armature voltage feedback, in the field weakening applications, is limited to the base speed value. The parameter CC4 takes on the function of the parameter CC5 that is removed.

Speed regulator bandwidth recalibration when calculated by speed self-tuning: The parameter CD8 takes on the function of the parameter CD9 that is removed.

Step function. The parameters CEC and CE2 have a new function (see item 5)

Kramer function. The parameters CEE and CE7 have been removed.

Motor thermal protection recalibration depending on speed. The parameter CE9 has been removed.

Speed gain recalibration as function of the diameter. The parameter CFA has a new function CFA = NoAdVR The parameter CF5 takes on the function of the parameter CF7 CF5 = ErNAR The parameters TH5-6-7-8 have been removed. The parameters TH1-2-3-4- take on a new function TH1 takes on the function of the parameter TH7 = TcFGp TH2 takes on the function of the parameter TH8= TcFGi TH3 = TacRF New function “Emergency ramp” XM1_14 = OFF e CBD = OFF TH4 = TdcRF New function “Emergency ramp” XM1_14 = OFF e CBD = OFF

Fixed time ramp The parameter CFD takes on the function of the parameter CFG that has been removed, so, CFD = SWCom4 The parameter CF4 takes on the function of the parameter CF6 (weighing time – Load weighing function). CF4= LW_Tm

The parameter CF6 takes on the function of the parameter CF8 that is removed, so, CF6 = ErN_T

The parameter CF7 is removed.

Logic handling of the switchboard - P.L.C. The parameters CHA, CHB, CHC, CHD, CHE,CH1 have been removed. It is no more possible to set the logic outputs OUT1-6 paramaeters DO1-6 as “CloseP and CloseF

The parameter CN5 takes on the function of the parameter CN6, so, CN5 = DiamS (Selection of the operating diameter source).The parameter CN6 has been removed.

The parameters COA-CO1-CO2-CO3 are replaced by the parameters CHA-CH1-CH2-CH3

Field reversing for Multi-motor Configuration has been removed

NOTE:

The firmware 2.6 is available on request.

The information is general and concerns the risks, for operators or for maintenance personnel, related to the operation and maintenance of the converter. The lack of observance of these rules may cause an hazard to the safety of people, with risk of death and of damaging the converter, motor or operating machine. Before operating with the unit, read the safety instructions.

CAUTION !

All the operations of electric maintenance and installation on the SPDM must be performed by qualified technicians. All the standard electric safety procedures must be respected: -Never touch inside the converter; only after making sure there is not a high temperature and/or in voltage. -Always wear protection shoes insulated, in rubber and protection glasses. -Never work alone. -Never connect to the system any grounded device of measurement or oscilloscope. -Never remove safety screens. -Always pay maximum attention when handling components or performing measurements inside the panel.

•

DANGER!

-The SPDM and all the other devices connected MUST BE GROUNDED IN A SUITABLE WAY. -The voltages on the terminals of output of the SPDM are dangerous, be it when the converter is activated, be it when the same is not operating. Also consider that the motor may turn in any moment as soon as the power supply is connected. -If the converter is installed in the panel, never operate it with the doors of the panel open.

•

DANGER! RISK OF FIRE, SERIOUS DAMAGE!

-The converter ≤ 600A has not internal fuses; foresee suitable fuses (see paragraph 7.3 section A for caliper and type immediately upstream the converter). Do not use fuses different from those specified; wrong fuses may cause fire, serious damage to personnel equipment and/or parts connected nearby. Some units need auxiliary fuses for the separated lines related to the fans and auxiliary circuits. -Do not apply power to the converter if you presume that inside of the container or of the components humidity has penetrated, dust or caustic/corrosive chemical agents.

•

Before performing maintenance on the unit, strictly follow these safety points: -Perform the procedure of block/exclusion of electric power supply and open the main disconnecting switch of the panel. -Make sure that all the power supplies which reach the SPDM (main and auxiliary power supply) are disconnected before performing maintenance on the converter. -Await at least thre (3) minutes after disconnecting power supply before performing maintenance on the unit.. Refer to the safety plate existing on all the converters. -The SPDM is supplied with many automatic functions of reset and restart which can restart automatically the unit. Do not activate these functions if there are dangerous situations. -Do not change the distances of insulation, nor remove materials and insulation covers. -Coordinate the voltage and the rated current of the motor and the converter. -If you must perform some insulation tests on the motor and on the cables, first disconnect the cables from the converter. Do not perform on the components of the SPDM of the test by high potential. -Pay attention not to damage any part of the SPDM during the movement. -Protect the converter from atmospheric agents and adverse environmental conditions (temperature, humidity, vibrations, collisions, etc). If you must store temporarily the converter outside, take special precautions (see paragraph 1.4 section A).

CAUTION

The SPDM contains components sensitive to the electrostatic charges; such components may be damaged if handles in a non suitable way. During the operations of maintenance or replacement of the electronic cards, follow the points indicated here below: Use a kit of maintenance for the electrostatic charges. You must take suitable precautions against the electrostatic discharge (ESD): • Wear static belts suitably grounded. • Handle the cards from the edges. • The cards should not enter in contact with highly insulating materials as plastic sheets, insulating surfaces, parts of synthetic tissues. • The cards shall be located on conductive surfaces only • The cards must be packed in conductive sheets before the shipment.

A1 GENERAL A1.1 Introduction Silcopac D is a family of Graetz three phase bridge compact converters for driving DC motors up to 4000 A, with enhanced features of accuracy and dynamic response. These are fully digital converters, because all control and regulation functions, including the thyristors firing, are performed by a 16 bit microcontroller. The use of the digital technique gives new important features: - the converter can be set by software in several ways, so as to match the system requirements; - a powerful converter diagnostics is provided; - the user can interact with the SPDM by means of a communication interface which allows to exchange data, commands and other information; - the current, the speed and e.m.f. loop adjustment can be automatically performed (self-tuning procedure); - the converter can be included in a centralized digital control system, by means of a serial communication line which allows large amounts of data to be exchanged; - sophisticated control algorithms can be easily implemented. The AC line frequency and the phase cyclic rotation do not affect the SPDM’s; they can operate at both 2 and 4 quadrants. In the 2 quadrants operating mode the Graetz bridge has 6 thyristors; the motor torque has an unique fixed rotation direction. In the 4 quadrants operating mode the bridge has 12 anti-parallel connected thyristors, without recirculation current; the motor torque has 2 rotation direction. A single control circuit assembly is provided for all the sizes, from 30 to 4000 A, and it is isolated from the power circuits. The software is available in the following releases: enhanced dedicated

for standard and complex applications. Standard Version With Profibus DP protocol. code C1C27N00F27 For the availability of the Profibus field bus the user must install the SPPB2 Kit)

Release 2.7 F

for special applications ( "S" Accurate Speed Ratio, "M" Spindle Control, “L” Ward Leonard).

Version 2.7 requires that on the control board (”C”) the programmed components (PALs) are installed as indicated by the following table. It is not interchangeable with the previous version 2.6, the replacement needs the parameters programming. Control Card CONDBE L3C85N00600 L4C20N06L00

PPRCRC BOARD. Description of the PPRCRA board

The PPRCRC board is installed inside the master converter in the parallel bridges application. The board compares the IAM current delivered from the MASTER (SPDM) with the current delivered by the SLAVE (RTT). If the difference between the two currents exceeds the permitted tolerance, the relay RL drops out. The protection will be disabled until the current of a bridge reaches its rated value. The board is fitted onto the P board by means of the relevant connectors and spacers. The C board of the SPDM will no longer be connected to the P board, but to the PPRCRC board through the connectors which keep the same codes as before. On the board, the circuit of the Ia monitor of the RTT module is present with outlet at the Faston terminals XM 11-3,4. A milliammeter may be connected to these terminals in d.c. current with 5 mA limit or a d.c. voltmeter with 10 V limit. The output can be set with the T1 trimmer. Should a voltmeter be used, the CV4 jumper must be closed. The output from the Ia monitor can be at a relative value (CV2 jumper closed, instrument at central zero) or at absolute value (CV2 open, instrument at side zero).

A10 OPTIONS AND FUNCTIONS 10.1 Interface Silcopac D digital converter is equipped with a device which manages the exchange of information and data with the external world by means of a serial link. It is possible to carry out a point-to-point connection by means of a RS 232 electric standard device. Use the proper serial communication software to link a personal computer by a point-to point connection to set parameters and carry out diagnostic operations specifically concerning the converter start-up and troubleshooting. This type of connection does not require any additional hardware (Fig. A10.1).

A10.2 List of auxiliary functions 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

Helper: it used to pilot a Silcopac D starter under current keeping the speed regulator in its saturation status. Pope: it is used to adjust a tangent winder to a fixed and re-calibrable current reference obtained by the speed regulator. Mechanical friction compensation: it is used to compensate static and dynamic mechanical friction of the cinematic chain which connects the motor. Torque Proof: it is usually used in lifting system to check the actual application of the traction torque before opening the brake. Load weighting: it is usually used in lifting systems with de-fluxed motor to re-calibrate the lifting speed as function of the possibility to overload the motor. Gain re-calibration as function of the flux function: it is used in the applications with speed regulation with defluxed motor to keep the regulator bandwidth constant for the whole speed interval. Speed reaction commutation: it is used to guarantee the speed regulation of a motor also in case of speed reaction loss (encoder or tacho loss), switching to the armature voltage regulation (only with not defluxed motors). Motopotentiometer: it is used to generate an internal speed reference which can be changed by means of increase and decrease commands. Internal references: are used to set fixed internal speed references (slow runs, etc.). Changeable parameters: this function is used to double the sets of available parameters for the regulators calibration, for internal references and for the ramps. Field inversion: this function is used to manage the reversibility with a one-direction starter, controlling a reversible energizer. Fast re-start: this function is used to manage the system re-start after a power failure. Speed error: it informs that the system is not controlling the motor speed. Tacho loss: allows to set the threshold of armature voltage above which the intervention of the “tachometer loss” protection (TachF) is enabled. races: The DRIVE TRACE and the THYRISTOR TRACE can be blocked also by the external logic input COM2. Diagnostic variables: The auxiliary variables Aux1, Aux2 and Aux3 can be customized to display the power provided by the axis of the motor (in % compared to the rated power). Double set complete of parameters: The function allows to store in memory two complete set of parameters. (as in the typical case of a winder whose configuration must be changed according to the material wound up). Personal Password: The user can use a personal password. Toggling of the references and commands: allows to toggle either the speed reference from Motopotentiometer to terminal board (input Ref XM1-33, XM1-34) and the contrary; or from serial line to input ‘Rif’. through the logic input COM4 (terminal XM6-1, XM6-2, I/O expansion board “SPDIO”).

A10.3 List of enhanced functions 1 2 3 4 5 6

Angular positioning regulator: it is used to position the drive shaft. Inertia compensation: it used to compensate the load inertias: constant or variable inertias as in the case of winders/unwinders. Mechanical backlash compensation: it is used to reduce the opening effect of mechanical backlash of the cinematic chain connecting the motor (for ex. reducers, couplers, etc.). Angular speed as function of the diameter: it is used to re-calibrate the angular speed according to the value of the diameter to keep the linear speed constant. Tension regulator: it is a PID regulator which can adjust the speed reference or impose a current reference. It compares the set reference with the reaction coming from the transducer (load cell, dandy roll, etc.). Winder: open loop tension regulators for torque adjusted axial or tangent winders/unwinders

A10.4 List of dedicated functions 1) 2) 3)

Accurate speed ratio: for the speed regulation of a small line (up to 6 motors) with automatic management of sliding devices of each section. Spindle: for the control of spindle machines. Ward Leonard: for the control of Ward Leonard machines and digital exciters.

RESOURCES USE

With the resources term, we mean the set of logic inputs, analog inputs and available functions for the configuration of drivemotor machine system. The parameters management supervises the programming of the new values so to avoid that a resource is used for more than one function.

B1 PARAMETERS The final set-up of the converter is completed by assigning the proper value to every parameter through the user interface; however the parameters requiring adjustments by the user are often minimal, because many of them normally require the default value. Default value means a factory setting value (stored in the EPROM memory) that the system automatically acquire if the user doesn't insert a different value through the interface. Grey shaded areas point out the most important parameters to be set or verified in the simplest applications. The new parameters available with the new release EPROM 2.7 are pointed out in yellow.

NOTE

Below the name of every parameter there is is serial number and his image in memory (W=word, B=byte). For the boolean parameters (ON/OFF) is indicated the bit inside his byte (exemple: CBB, 288.1 means that the parameter CBB is associated to the bit 1 of the byte with address 288). The bit numeration begins from 0 (least significative bit, LSB) till to 7 (more significative bit, MSB). For the parameters expressed in % please note that the normalization factor is 13107 (3333 hex) so the value 100% meets to 13107 and –100% meets to 54429 (CCCD hex). The enumerative parameters, that is these that have a selector function (for example CA1),takes values from 0 to N-1 where N is the selector position number.

Number of max delay to be executed during the armature current reversing procedure, after the zero current signal; normally CA7 = 0. If Silcopac D is used as exciter, then CA7 = 20 (avg recommended value). Intervention threshold value of the armature current reversing procedure. If the current reference, on sign change, drops below this threshold, the reversing procedure will be enabled. Otherwise the current reference will be zeroed without the reversing procedure. Fixed current limits: Upper limit: positive limit fixed by the (+) CA9 parameter. Lower limit: negative limit fixed by the (-) CA9 parameter. Group B - SPEED REG. Speed regulator enabled. Filter enable on sign of the speed feedback from encoder. The filter rejects a sign reversing if the reversal isn't permanent during at least 3 consecutive readings. The filter isn't enabled if the system is in zero speed conditions, displayed by a 0 on the 7 segment LED. Zeroing of the integral term when the speed reference = 0. Enable this function to avoid the "turn back" at the motor stop and braking, setting the speed reference = 0. Don't enable this function in lifting applications.

Group C - PROTECTIONS

This group includes the parameters used to enable the Protections intervention. See also the next group D - ALARMS, that includes the enabling parameters of the alarms intervention; the parameters of groups C and D are related each one to other because each intervention can be defined as follows: Protection:if the intervention is reported and the converter is stopped (DCx parameter of group DC-PROTECTIONS); if the intervention is reported without the stop of the converter (DDy parameter of group DD-ALARMS); Alarm: x, y identify the active protection or alarm (i.e. DCA = line loss).

(3) Watchdog. (4) Max armature voltage. The intervention threshold can be set through the DC5 parameter. The intervention may be also caused by the voltage transducer failure; in this case the protection will be active if the motor speed rises beyond the basic speed (DB7 parameter), while the transducer reports a voltage value lower than 50% of the rated value. (5) Motor field loss. The intervention may be also caused by the exciter failure. The minimum intervention threshold can be adjusted by the DC3 parameter. (6) Tacho signal loss. The protection is active when the armature voltage rises beyond the threshold value set by the parameter DD2, at null speed feedback. (tacho generator or encoder broken) This protection is also active when the tacho voltage is applied with reversed polarity. See also par. DDA. (7) Ventilation loss. Converter heat sink thermostat intervention. See also par. DDB. (8) Motor over temperature. For proper operation of this protection, the DB6 parameter must be programmed as follow: DB6 = 100 * IaN / IaM IaN = rated armature current IaM = max armature current See DC8 and DDC parameters too. (9) Converter over temperature. For proper operation of this protection, the following parameters must be programmed: DA3 = Converter size DB3 = IaM See DDD parameter too. (10) Serial link loss. The intervention occurs if the serial communication is broken. The protection is active only if the serial link is enabled. See note %% par. C2.1

If the converter receives current or speed references from the serial line, serial link loss disabling must be carried out with utmost care. In this condition, when serial link loss occurs, the converter uses the last received reference: the user can therefore select the next action, using the signal coming from either digital outputs configured as ‘Alarm’ (see the description of parameters DDE, DEF and DO1...DO6.

(0) Line loss. The system forces the converter to the maximum delay, followed by pulses suppression. This hardware protection cannot disabled. (1) External protection. An external protection is active opening the terminal XM1-20, disabling the converter; the relay K2 (converter ready) is not de-energized. The intervention is not internally stored, so the converter will be enabled again if the protection loss causes the closing of terminal XM1-20. This hardware protection cannot be disabled. (2) Max instantaneous current. The intervention of this protection occurs when the voltage drop on the CT load resistor rises beyond 6.3 V; see par. 3.3 of manual C Section. This hardware protection cannot be disabled.

The intervention occurs if the stall time, with the motor in current limit conditions, rises beyond the value set by DC6. This protection is not active if the current limit is lower than 25%. of IaN. The IaN value is set by DB6. See DDF parameter too.

Com3

input is active:

the function is enabled; the speed regulator will be forced to saturate enabling the speed reference summing term defined through the CE1 parameter (invitation speed).

To allow the speed regulator saturation even at the maximum reference, program TC4 and TC5 parameters according to the following formula: TC4 = TC4P + CE1 where TC4P = TC4 parameter previous value; TC5 = TC5P - CE1 where TC5P = TC5 parameter previous value; The upper current limit is acquired at Ean1 analog input that is driven by the Master converter. Commands Com1 and Com2 act on the DJ3 parameter which recalibrates the Ean1 analog input (Com1 = increase; Com2 = decrease) allowing load share. The resulting torque is however a (variable) percentage of the Master converter torque. If the Helper (slave) converter slips, then the speed regulator goes out of its saturation status and avoids the motor exceeding the master speed plus the invitation speed. If the speed reference has a negative value, the function drives the lower current limit and the term related to the invitation speed will be subtracted. On the Com3 command falling edge the DJ3 parameter is written in the EEprom memory to store the last imposed load share. Note ##: Pwm2 analog output is normally reserved to the field current reference.

Com3 input active: the function is enabled; the speed regulator is forced to saturate enabling the summing term to the speed reference defined by CE1 parameter (invitation speed). Set TC4 and TC5 parameters according to the following formula: TC4 = TC4P + CE1; where TC4P = TC4 previous value; TC5 = TC5P - CE1; where TC5P = TC5 previous value; to allow the speed regulation saturation at the max reference value too. The current reference value that is active at the Com3 rising edge will be stored and substituted to the upper current limit. Commands Com1 and Com2 act on the stored current reference (Com1 = increase; Com2 = decrease) increasing or decreasing thus the applied tension (the slope can be programmed by the CB4 parameter). At the Com3 falling edge, the speed reference summing term will be immediately zeroed and the current upper limit will be acquired again by TA3; the Speed Regulator is immediately desaturated zeroing the integral term and the speed error. If the slope is enabled (TE1 and TE2 parameters), the bumpless disconnection of the Pope function is thus obtained: it allows the passage from current regulation to speed regulation without discontinuities in the current reference.

current reference summing term needed to compensate the mechanical friction losses. mechanical friction rate not depending on the speed. coefficient depending on the mechanical friction rate as linear function of the speed.

Practical procedure for the experimental evaluation of CE3 and CE4 parameters: 1) Through the Setup Reference function (section C, par. 1.2.7), set a speed reference equal to 1% of the nominal speed. 2) Read Ia(SR) value (section C, par. 1.2.7 point "A"): current needed to compensate the mechanical friction at this speed. Set CE3 parameter with Ia(SR) value (constant rate of the mechanical friction). 3) Through the Setup Reference function (section C, par. 1.2.7), set a speed reference equal to 100% of the nominal speed. 4) Read Ia(SR) value (section C, par. 1.2.7 point "A"): current needed to compensate the mechanical friction at this speed. Set CE4 parameter according to the following formula: CE4 = (Ia(SR) - CE3). The term evaluated for the frictions compensation will be summed to the current reference delivered by the speed regulator before the dual slope digital filter. In the case of negative speed feedback, the mechanical friction compensation gives a negative summing term (correction < 0). It is possible to display the term evaluated for the mechanical friction compensation by setting one of the parameters DG5, DG6 and DG7 with the M_Loss value.

Torque proof

The function is used for the lifting applications. The function purpose is to reduce or to remove the speed transient that occurs at the brake opening time. Before brake opening the motor is controlled by a limited torque (torque preset) so not to damage the motor/brake system and to ensure a quick transient after the brake opening.

Function description The function is enabled by the parameter CFB = ON and digital input COM3 = OFF. When the system is in suppression status (STATUS = SUPPR), the current limits are preset to the range (+/-) set by parameter CF1. The motor at the start will be fed by that current value BRAKE OPENING The brake opening/closing command is given by a logic output OUT1-OUT6 (parameters DO1-DO6) set as ‘T_proof ’. When start command is given (transition the the regulation status, STATUS = REGUL), the brake is locked till the system reaches the current limit set by parameter CF1. The current limits set by parameters TA3 and TA4 do not care. The status “system in current limits” can be carried out to a digital output (see the parameters DO1…DO6) or displaied on the keypad (see NOTA 3 paragraph C1.3). The brake opening is commanded when the current reaches the set limits and at the same time a timer is set (time setting by the parameter CF2 in software cycles,) at the time end the current limits go back to the values set by the parameters TA3 and TA4. The delay required to go back to the previous limits balances the delay for opening the brake and then avoids that the motor generates the maximum torque with the brake still closed (brake opening transient). BRAKE CLOSING The brake will be closed when the motor reaches the zero speed after the stop. Parameters Parameters: value Function CFB ON Torque-Proof aux function enabled. See description.

Exemple: The picture shows the typical trend of the motor current and speed during a lifting operation At the start the current rises to the limit value CF1 in a time that is a function of the current regulator tuning. When the CF1 value is reached the digital output OUT1, set to ‘T_proof ‘, goes high and opens the brake. After the delay, set by CF2, the current limits go back to the values set by the parameters TA3 and TA4 and, if the brake is unlocked, the motor starts. At the Stop, the motor decelerates till zero speed, at this moment the digital output OUT1 goes back to low status and close the brake.

Commands Com3

(terminal XM1-19) not active: function enabled.

Function description The function, used in lifting applications (cranes, etc.) which operate with de-fluxed motors, allows to always obtain maximum motor speed, according to the required torque. This is done by recalibrating the speed reference value on coefficient K, so as to avoid the motor current exceeding the nominal value in steady state conditions. At the beginning, before weighing (motor speed is zero), the recalibration coefficient is:

K0 =

DB7 100%

with DB7 as base speed. Weighing and speed reference recalibration are only performed when the motor reaches base speed; considering K start value, base speed is only reached if speed reference is set to 100%. On reaching base speed, armature current Ia(Nbase) is measured and recalibration coefficient K is recalculated as follows:

DB6 Ia(Nbase)

with DB6 as nominal current and DB7 as base speed. Ia(Nbase) is the average current calculated within a time interval set by parameter CF6, expressed in software cycles (see parameter CD3), during which speed is kept equal to base speed. The whole speed recalibration procedure requires twice the time set by CF6. CF3 parameter is used to compensate the friction torque during the lowering; it is adjusted so that the lifting and lowering speed of the system, with the same load, are equal.

Function description This function acts when the condition for the tacho loss protection occurs, i.e. either when armature voltage exceeds by 50% its rated value, with no tacho (or encoder) feedback, or if tacho (or encoder) feedback sign is inverted. This function replaces the tacho/encoder speed feedback value with the value calculated depending on armature voltage [CB3 parameter will be automatically set to F(Ud)]. Flux reference is assumed equal to the value set by CC4 parameter. The speed regulator gains are replaced with those set by TH7 and TH8 parameters (proportional and integral only). The system signals tacho loss alarm status (DDA parameter is automatically set to ON). In this case, tacho loss alarm can not be reset; it can be sent to any logic outputs by setting one of DO1,..., DO6 to “Alarm”. When the system is restored, the original configuration is resumed by a reset sequence.

The software motopotentiometer can be used as speed reference source to generate the speed reference when CB1 parameter is set to ‘MPotFw’ or ‘MPotC3’.

It is possible to set the ramp time, in seconds, of the motopotentiometer by the CB4 parameter. CBE parameter set to ON enables the storage of the last reference set on CB9 parameter. In this way, the last set reference is held after a reset sequence and with the converter not powered also. To use this function, JP4 jumper must be in 1-2 position. If the quick restart function is enabled, in the event of power loss the motopotentiometer reference is automatically stored to CB9 parameter.

Field reversing

The function field inversion is used in the applications in which it is required a bidirectonal regenerative operation from a motor in c.c. supplied with an unidirectional converter SILCOPAC D (in short. SPDM). Differently from what occurs when using a reversible converter the torque inversion is managed by operating on the field current instead of on the armature current. The constant of time of the field circuit is much more greater than that of the armature current of the motor for which the whole phase of inversion may require a relatively long time, that limits the applications of this function to the only cases in which it is not necessary a high dynamics of the torque inversions. D10.1 Parameters The following list includes all parameters concerning the SPDM...U mentioned in the description of the function "field inversion". DA2 = Unid. DM2 = Ifo CCA = ON CCB = ON CA8 CC1

CC3 CC2

The function field inversion cannot be enabled if the converter is reversible. Therefore, before enabling the function it is necessary to configure the parameter DA2 as ‘Unid’. The function field inversion cannot be enabled if before the analog output PWM2 (terminal XM1-39) has not been configured to provide the reference of current of field. Therefore, before enabling the function you must configure the parameter DM2 as ‘Ifo’ (value of default). Enabling of the regulator of the electromotive force; Enabling of the function field inversion; Threshold of intervention of the function field inversion. The procedure of field inversion starts as soon as the current reference Ia0 coming from the speed regulator (or from another source which can be established with the parameter CA1) changes the sign and in absolute value exceeds the threshold which was set with the parameter CA8. Field saving. The field current of the motor is reduced at the value programmed in CC1. The reduction of the field current occurs only if the status of the converter is SUPPRESSION or PROTECTION. Furthermore the start of the reduction of current occurs after a programmable delay with the parameter CC3 from the instant of passage from the status of REGULATION to the status of SUPPRESSION/PROTECTION. Intervention time of of the "field saving" function expressed in software cycles. The corresponding delay, in seconds, is worth CC3·CD3. Delay time of the enabling of the impulses to the thyristors at the end of the field inversion expressed in software cycles. The corresponding delay, expressed in seconds, is worth CC2·CD3. SPDM...U

Figure D10.1 Configuration with single motor D10.2 Functions description In figure D10.2 it is represented the simplified diagram for the regulation of the motor speed. The procedure of field inversion starts as soon as the reference of current Ia0 -coming from the speed regulator or another source which can be established with the parameter CA1- change its sign and exceeds in absolute value the threshold which was set with the parameter CA8. During the whole inversion the firing pulses of the thyristors of the armature bridge are generated with limit delay (165°) and the regulator of current remains disabled. The procedure ends when there are at the same time the following three conditions: 1. the current of field If has the same sign of the reference If0; 2. there has been an end to the conditions of intervention of the protection lack of field and transducer of armature voltage malfunctioning (see description of the parameters DCF, DC3, and DCE); 3. The difference between the reference If0.of the current of field and the reaction If is lower than 50%. At the end of the procedure of inversion, the activation of the current regulator may be delayed if you wish to allow to the current of field to reach its new operating value.

The parameter CC2 allows to obtain such delay in terms of software cycles. The corresponding time may be calculated with the formula: time of delay = CC2·CD3 [s] where CD3 is a parameter which may be 10, 5 or 3.3 ms. For example, if CD3=10 ms and CC2 = 20 then the delay time is worth CD3·CC2 = 200ms. During the field inversion the current regulator of the SPDM remains disabled; this involves that, at the moment of unlock of the regulator, the speed of the motor and the reference of speed can be very different and as a consequence you may have a high request of current made by the speed regulator, with possible negative consequences on the mechanics. The function field inversion, if used with the ramp enabled (terminal XM1-14), allows to obtain a soft transaction (“bumpless”) at the moment of the unlock of the current regulator. In the moment of the unlock, the function equalizes the operating reference of speed ( N0 ) to the feedback of speed ( N ) and sets to zero the integrator internal to the speed regulator. Subsequently, the operating reference of speed N0 is changed linearly, through the ramp function, from the value N up to a speed reference value existing upstream the ramp. In this way the request of current Ia0Nrg made by the speed regulator does not undergo a sudden increase, but gets a gradual evolution determined by the slope of the ramp.

Figure D10.2 Adjustment diagram for the configuration with single motor Upon startup, the motor starts immediately to turn in the direction required if the field has the correct direction; however, if the field has not a correct direction, the speed regulator control the inversion and maintains the system in a status of wait. until the procedure of inversion is achieved. The waiting time of the completion of the inversion may represent a problem, especially in the repeated startup and stop maneuvers in the two directions of run (maneuvers of jog, for example). This waiting time is shortened if, after the stop of the motor, the field is lowered to a minimum value through he function field saving, which reduces the intensity of the field to the value pre-established with the parameter CC1. After the stop of the motor, furthermore, the reduction of the field might be delayed for a time which can be set from 1 to 9999 software cycles through the parameter CC3. The corresponding delay expressed in seconds is: time of delay = CC3·CD3

[s].

If during the procedure of inversion of the field, the speed regulator requires a further inversion, it is immediately operated with no need to await that the first inversion is achieved. The field current feedback is acquired on the dedicated analog input If (terminal XM1-28, mass on XM1-41; +10V; JP25 closed on pin 1 and 2). The inversed tachometer protection is not activated when it is enabled the function of field inversion. D10.3

Signalings and diagnostic

For the signalling purposes, two of the six logic outputs available in the SPDM can be configured to indicate the direction of the field and the status of the converter concerning the phase of the field inversion. The two logic outputs chosen, OUTx -& OUTy , must be respectively configured as ‘FLdIn+‘ and ‘FldIn-‘ through the parameters DOx and DOy. The table D10.1 shows the status of the two logic outputs according to the status of the converter. OUT x DOx = FldIn+ 0 0 1 1

OUT y DOy = FldIn0 1 0 1

Status of the converter The converter is in status of protection and/or suppression. Direction of the field is undefined. Converter not in phase of field inversion. The field has positive direction. Converter not in phase of field inversion. The field has negative direction. Converter in phase of inversion.

Table D10.1: Status of the two logic outputs according to the status of the converter. In the table the indexes x and y refer to one of the six logic outputs of which the output OUT1 and the output OUT2 are available on the terminal board XM1 of the SPDM and the remaining outputs OUT3, OUT4, OUT5 and OUT6 are available on the expansion SPDIO1. The reference of current on the output of the speed regulator IaoNrg, indicated in the diagram of figure 6.2, can be displayed on the display of the keypad, or converted in analog form, by suitably configuring the parameters DG5, DG6 or DG7 and the parameters DM1, DM2 and DM3 Example: DG5 = IaoNrg DM1 = Aux1

Quick restart

The quick restart function handles the intervention conditions of the "Line Loss" and "Line beyond tolerance" protections, avoiding the storage of the lock status. In this way the system restart is allowed at the return of the normal operating conditions, without the intervention of the user and avoiding the machine stop. If the speed reference is obtained by means of the motor potentiometer, if there is no supply mains, it is automatically stored in the CB9 parameter so as to be reused during the restarting. The function is enabled by setting the parameter CDB QuickS = ON. More precisely the function is referred to the following definitions:

• Line loss:

it is a supply voltage (terminal block XM2) drop under a fixed threshold equal to 50% of the main voltage, of at least 5ms duration.

• Line Drop:

it is a falling of the supply voltage (terminal block XM2) under a programmable threshold (Uv0Min), with duration greater then 20ms. The threshold value equals the 60% of the nominal line voltage, if the armature voltage is in the range 0 to 50% of the nominal voltage; if the armature voltage is higher than 50%, the threshold value can be determined by to the following formula: Line drop threshold

UVo (%)

UVoMin = 60%+

(Ud −50%) ⋅ (DC1−60%) 50%

DC1 60

Ud (%)

where: Uv0Min = DC1 = Ud=

is the threshold operating value for the line drop intervention (percentage value of the nominal supply voltage, DB1 parameter). is the minimum threshold parameter for the line beyond tolerance protection intervention. is the armature voltage as percentage of the nominal voltage (DB4 parameter).

When the function is enabled, if a line loss or a line drop occur, the system will begin the following sequence: −

It goes into protection status displaying this condition on the user interface and doesn't execute the storage procedure of the first occurred protection (items 1.1 and 1.2, Section C of this Manual).

−

When the supply voltage returns to normal value, the system executes a bumpless restart of the machine.

−

If the line loss or the line drop have a duration less than 100ms, the control circuits of the converter remain properly powered and synchronized with the supply line, allowing an instant restart; if the line loss or the line drop have a duration greater than 100ms, during the restart phase (true system power-on) some tests on the circuits and the line re-synchronization is executed, adding about a 500ms delay.

Speed error

This function is used in hoisting applications, where is necessary to keep under control the speed regulator. A logic output (OUT1, OUT2, OUT3, OUT4, OU5 and OUT6) is activated when the absolute value of speed error (Speed ref. - Speed feedback) is higher than a programmable value and this condition lasts for a programmable interval.

The function is normally used in applications where two motors are used (ex. cranes); the first motor speed feedback comes from a tachometer or from an encoder; the second motor speed feedback is calculated from the armature voltage. The switch from one speed feedback source to the other one must be carried out only when motors are still. The armature voltage feedback motor must always work in the constant torque range (full flux). In addition, the armature voltage feedback motor flux can be set through CC4 parameter.

The logic outputs can be customized to signal if the field current is lower than the parameter CC4 (new parameter ‘IfThr’). The signalling of current for a field lower than CC4 is obtained by programming the parameters DO1,...,DO6 (corresponding to outputs OUT1,...,OUT6) as IfCE6. The extension of the hysteresis is established by parameter CB6.

Traces

The DRIVE TRACE and the THYRISTOR TRACE can be blocked, besides by the intervention of a protection, also by the external logic input COM2. The possibility to block the two traces from the outside allows to display the status of the drive in a special moment with no need for a protection to operate. The traces, after the stop, can be printed in any moment, provided that power supply to the control is not switched off, nor a reset is made. The function which allows the stop of the traces from COM2 is enabled with the parameter DGD ‘C2Stop’ (new parameter). The traces are frosted in correspondence of the transition low→high of COM2. the restart of the traces is obtained • by disabling the function (DGD = OFF), or • resetting the converter, or • passing from the status of protection/suppression to the status of regulation, independently from the status of COM2. To know the status of the traces (activated or blocked) we must access to the menu STATUS in which a blinking dot indicates if the traces is operating; if, on the contrary, the dot is fixed, then the trace is blocked.

Double set complete of parameters

It is possible, with this function, to store in memory two complete set of parameters, the function it enabled by setting the parameter CDG=ON. The double set of parameters can be useful, for example, to have two different configurations of the adjusters, as in the typical case of a winder whose configuration must be changed according to the material wound up: - Tension regulation with control of the current limit (configuration 3 of the manual SPDM); - Tension regulation with control of the speed reference and calculation of angular speed (configuration 1 of the manual SPDM) The passage from the first to the second set is made during the reset of the converter and the set of parameters is established by input COM1. During the reset if COM1 = OFF ⇒ first set if COM1 = ON ⇒ second set The eventual function assigned to COM1 (e.g. the motopotentiometer) is suspended during the procedure of change. The sequence of commands to obtain the change of the set, graphically illustrated in figure 5.1, is as follows: 1) disable the converter opening the terminal XM1 - 20 (External protection) (instant T1); 2) put COM1 according to the desired set (instant T2); 3) reset the converter (supply XM1-21 Reset for at least 0.2 sec) (instant T3); 4) upon the release of the reset (instant T4), COM1 it must remain in the position which was set in (2) for at least 1 sec, i.e. the time necessary for the check to end the procedure of reset. At the end of the procedure of reset, the converter SPDM assumes the set of parameters corresponding to the position of COM1 (OFF⇒1° set, ON⇒2° set); 5) bring back COM1 to the original status (instant T5); 6) enable the converter by power supplying the terminal XM1 - 20 (External protection) (instant T6); XM 1-20 KP

“BUMPLESS” function.

The “Bumpless” function is used when the drive must start with a spinning motor. The drive first detects the actual motor speed then it resumes control of the motor and accelerates it from the restart speed to the set value of speed reference. The previous release the control started from zero speed reference conseguently sharp braking occurred. The function is always enabled, it does not need any setting but it needs the ramp function.

Regenaritive braking disable.

The function, effective with four quadrant converters, allows to avoid the fuses breaking in some applications in which for different causes (excessive reduction of the power supply voltage... ) it has no been possible to keep the proper margin between the power supply voltage and the armature voltage. The function disable the regenerative braking if the armature voltage is greater than a programmable threshold value. It is possible to enable the function by the parameter CEC (CEC= Dis Reg = ON/OFF) and to set the threshold by the parameter CE2 ( Output voltage threshold: if the armature voltage value is greater than the threshold value the regenerative braking is disabled). If the armature voltage decreases below the value equivalent to the threshold value the regenerative braking is enabled.

Toggling of the references and commands

The selection of the origin of reference of speed (parameter CB1) foresees two new possibilities: ‘MPoRif’ and ‘SerRif’. The first one allows to toggle the speed reference from Motopotentiometer to terminal board (input Ref XM1-33, XM1-34) and the contrary; the second one commutes the reference from serial line to input ‘Rif’. In both cases, the commutation is performed through the logic input COM4 (terminal XM6-1, XM6-2, expansion card I/O SPDIO). CB1 = MPoRif CB1 = SerRif CFG = ON

194

(New) The speed reference comes from the motopotentiometer when the input COM4 is OFF. If COM4 is brought to ON the speed reference is read by the analog input ‘Rif’. (New) The speed reference comes from the serial line when the input COM4 is OFF. If COM4 is brought to ON the speed reference is read by the analog input ‘Rif’; in this case the protection of serial loss is automatically masked. (New) This parameter enables the function of exchange of the commands (Start, Ramp, IntRef1, IntRef2, Com1, Com2, Com3) from serial to terminal board through the logic input COM4. This function is activated only if CB1 is programmed as SerRif, in this way the commands and the references can be simultaneously toggled from serial to terminal board through the only command COM4. COM4 = OFF commands from serial line (if DEB = ON). COM4 = ON commands from terminal board

The enhanced functions must be enabled and configured by appropriate parameters, grouped by their function in Configuration and Tuning Parameters. Some of these functions are incompatible each one to other because they use the same system resources. For the same reason the enhanced functions may be incompatible with some of the auxiliary functions. Any attempts to contemporary enable the auxiliary and/or enhanced functions, incompatible each one to other, fail and result in the CONSISTENCY ERROR message on the display (parameters consistency error). The using of some enhanced functions implies a proper configuration of the converter hardware (applications of some options and/or specific machine equipment) that will be discussed in the setting up procedure description of the function itself.

ANGULAR POSITION REGULATOR

The function is used to perform the angular positioning of the motor shaft in respect to a position reference set by a parameter (two distinct references as function of the motor rotation direction). E1.1

Required hardware

The motor must be equipped with an Encoder. The zero pulse can be generated by the encoder itself (three channels Encoder) or it can be independently generated. E1.2

Parameters setting

CB3 = Encod

Speed feedback from the Encoder.

CBD = ON

Ramp command bypass enable.

CGA = ON

Function enable.

CGB

Set to ON if the converter suppression status is required after the positioning. Set to OFF if the continuous converter regulation is required even after the positioning.

CG2

Set to the absolute value of the approaching speed (percent value of the speed full scale: DB5 parameter).

CG3

Set to forward angular position reference value (indicated as Encoder pulses number).

CG4

Set to reverse angular position reference value (indicated as Encoder pulses number).

CG1

It is a multiplying coefficient of parameters CG3 and CG4. If the set value is not zero, then the position reference is recalibrated according to the following formula:

RifP = RifP • CG1

where RifP =

position reference CG3 for positive rotation direction; CG4 for negative rotation direction.

CG5

Set to the maximum allowable position error value (Encoder pulses number). If the position error is lower than the value set by this parameter, the system will go in State = "Positioning completed" (see CGB parameter).

TJ1

Set to the proportional gain value of the position regulator.

TJ2

Set to the value which the speed regulator proportional gain must assume after the positioning (only if CGB = OFF).

TJ3

Set to the value which the speed regulator integral gain must assume after the positioning (only if CGB = OFF).

TJ4

Set to the value which the speed regulator derivative gain must assume after the positioning (only if CGB = OFF).

DO1 - DO6

IMSPD027I

It is possible to program each one of parameters DO1 to DO6 with the value "ErrP = 0": the relevant logic output (OUT1 OUT6) will be active when the position error will be lower than the value set by CG5 parameter (after the positioning).

Logic commands

COM2

Terminal XM1-18. If enabled, the positioning will be reached. If disabled, the motor is speed regulated. Function description

E1.4

When COM2 command is disabled, the angular position regulator is excluded and the motor will be speed regulated. When COM2 command become enabled, the converter will reach the approaching speed, which sign depends on the rotation direction that the motor had when COM2 was enabled. When the approaching speed will be reached and kept for 200msec min time, the zero pulse acquisition phase will begin. The position reference is chosen among the two parameters CG3 and CG4 depending on the motor rotation direction (CG3 if forward speed; CG4 if reverse speed). If the gear ratio of the motor is 1:1 and the same position is required both in forward and reverse speed conditions, set CG4 parameter according to the following formula: CG4 = DB8 - CG3

where: DB8 = Encoder pulses number / turn ratio.

When the position error absolute value is lower than the value set by CG5 parameter, the motor is stopped and the positioning ends. If CGB parameter is set to ON, after the positioning the converter will go in suppression status; on the seven segments display the following symbols will appear: H-3

alternatively blinking

and using the Status function, the display shows the message: STATUS SUPPR. Disable Opt. Fun. If CGB parameter is set to OFF, at the end of the positioning the converter continues to hold the motor position and the proportional, integral and derivative gains set by parameters TJ2, TJ3 and TJ4 respectively will be imposed to the speed regulator. When different gains than those set for the normal operating conditions are not requested to be imposed to the speed regulator, set parameters TJ2, TJ3 and TJ4 to the same values programmed on parameters TC1, TC2 and TC3 respectively (TJ2 = TC1, TJ3 = TC2 and TJ4 = TC5).

INERTIA COMPENSATION

The function is normally used in speed regulated systems where the motor drives a very inertial load. When a speed variation has to be impressed to these systems, the machine inertia must be compensated introducing a summing term to the current reference which depends on the speed variation itself. E2.1

Parameters setting

CMA = ON CM1 = Const. CM6 E2.2

Function enable. Calculation of the term for the inertia compensation as function of the speed variations. Set to the machine acceleration time value (as seconds).

Measure of the machine acceleration time

It is defined as machine acceleration time the period which the motor takes to reach the basic speed starting from zero speed, when it operates at the nominal armature current. It can be measured according to the following sequence: − set DM3 parameter to N value to configure the Pwm3 logic output as signal proportional to the speed (default value) (par. 8.3.2). − connect a scope to Pwm3 logic output (terminals XM1-40, 41) − set scope to 2V/div − set a scope timebase adequate to display the complete phenomena (e.g. 2-5 s/div) − set DC4 parameter to the value programmed on DB7 parameter − by SETUP REFERENCE function set an armature current reference (FIXED) equal to the value set for the DB6 parameter (nominal motor current) − enabling the converter (Start command), the motor accelerates until the max speed protection occurs (P - B) − store the waveform on the scope and measure the time between zero speed and basic speed (remember that 10V voltage value at the analog output means maximum speed (100%) − restore the normal conditions and reset the converter. Example: Max speed basic speed max current nominal current

BACK-LASH COMPENSATION

The function is used to null the opening effect of the back-lash that occurs during the reverse phase of the armature current. The compensation is obtained reducing the current value (torque on the motor shaft), at the end of the bridge reversing sequence, during a sufficiently long time and at a sufficiently low value to allow the back-lash recovery avoiding the rebounds. At the end of this phase, the current limits are restored to their original values through a ramp which duration can be programmed. E3.1

Note:

The values of CO1, CO2 and CO3 must be chosen in an experimental way for the back-lash recovery, at the end of the current reversing phase, so that no rebounds or temporary instability effects on the current and/or on the speed take place. CO3 % Upper limit Reversing +CO1 -CO1

ANGULAR SPEED AS FUNCTION OF THE DIAMETER (ADP)

The function is used in those applications where, given a linear speed and acquired the diameter as analog signal, the motor has to be speed regulated changing the linear speed reference to angular speed reference evaluated as function of the diameter, so that the peripheral speed will have a constant value which do not depend on diameter variations. A typical application, e.g., is a speed regulated winder with dancer control: 100% Diameter Linear speed Minimum diameter Dancer control

E4.1

Angular speed

Required hardware

The diameter transducer device must generate a 0-10V analog signal to be connected to Ean1 or Ean2 analog input (terminals XM1-29, 31 and XM1-30, 31); a signal equal to 0V means minimum diameter (set by CN1 parameter); a signal equal to 10V means maximum diameter (100%). E4.2

Function calibration

The function calibration has to be performed according to the following sequence: a) set CBH parameter to OFF. b) connect to the coiler-uncoiler spindle the minimum diameter coil. c) check that in these conditions the diameter transducer have null output. d) connect to the spindle the maximum diameter coil. e) check that in these conditions the diameter transducer have 10V output. f)

remove the maximum diameter coil.

g) set, through the Setup Reference - Continuous Speed Ref. function, a 100% angular speed reference. h) check that in these conditions (minimum diameter and maximum angular speed) the linear speed, measured on the minimum diameter spindle, equal the maximum line speed (equivalent to 100% of the value shown by the Instrument Mode function at the No item). i)

if the a.m. conditions is not true, perform the calibration acting on CB8 parameter (if CB3 = Encod) or acting on DJ1 parameter (if CB3 = Tach) until the proper linear speed value will be reached.

Set to minimum diameter value (as percent of the maximum diameter).

CN2

Set to P_CN3 value if the initial diameter is acquired from CN3 parameter. Set to Ean1 value if the initial diameter is acquired from an analog signal (0-10V) connected to terminals XM1-29, 31. Set to Ean2 value if the initial diameter is acquired from an analog signal (0-10V) connected to terminals XM1-30, 31.

CL3

Set to Wind value if the diameter assumes increasing value (winder reel). Set to Unwind value if the diameter assumes decreasing value (un-winder reel).

CBH

Set to ON to enable the function.

E4.4

Diameter acquisition logic

The signal provided by the diameter transducer is acquired reading the voltage value at the proper analog input (CN6 parameter). At 0V value the diameter has the minimum value (CN1 parameter). At 10V value the diameter has the maximum value (100%). Remember that it is possible to perform the proper recalibrations of the voltage value at the analog input, setting the parameters DH3, DH4, DJ3, DJ4, DK3, DK4, DLC, DLD. The diameter variations are limited by a ramp which duration can be set by CN5 parameter. If CL3 parameter is set to Wind, the diameter can take only increasing values; diameter values lower than the last acquired one will be ignored. If CL3 parameter is set to Unwind, the diameter can take only decreasing values; diameter values greater than the last acquired one will be ignored. Setting one of the logic output (DO1 to DO6 parameters) to DiamErr value, if the error between the new diameter value and the last acquired one is greater than 20%, a diameter error warning will occur (the logic output changes to its active status). E4.4.1

Logic commands

Com1

Terminal XM1-17. The rising edge of this input (transition from inactive to active command) starts a sequence that acquires through a 10s ramp, at angular speed lower than 20%, the measured diameter value bypassing the filter set by CL3 parameter and the ramp set by CN5 parameter.

Com2

Terminal XM1-18. The rising edge of this input (transition from inactive to active command) starts the instantaneous acquisition of the initial diameter which provenience depends on CN2 setting. If CN2 is set to Ean1 or Ean2, the analog signal indicating the initial diameter (e.g. potentiometer) must have 0 to 10V swing, where 0V corresponds to the value set by CN1 parameter (minimum diameter) and 10V corresponds to 100% (maximum diameter).

E4.5

Function description

The linear speed reference is changed, as function of the diameter value, to an angular speed reference that will be sent to the speed regulator. The evaluated angular speed reference value can be displayed through the Instrument Mode function at the No item. The acquired line speed value can be displayed by an auxiliary variable setting one of DG5, DG6, and DG7 parameters to Line_N value (set the displaying of the selected aux variable through the Instrument Mode function). The acquired diameter value can be displayed by an auxiliary variable setting one of DG5, DG6 and DG7 parameters to Diam value.

The tension can be regulated by closed loop (presence of the tension feedback signal) or by open loop (calculation of the current needed to generate the torque resulting in the desired tension). E5.1

Closed loop regulation

The tension reference is compared to the tension feedback; the resulting error is processed by a proportional-integral module generating a term that corrects the speed reference or that can be used as current limit (saturating the speed regulator by a term to be summed to the reference). To

Tension feedback

Open loop regulation

In this case no comparison is performed between the reference value and its feedback, and then it is needed to calculate all terms establishing the total torque supplied to the system, e.g. the mechanical losses and the inertia effects.

Zero speed tension

Parameter CJ3 allows to enable the acquisition of a tension reference set by parameter CJ4 that replaces the selected tension reference through parameter CJ1 according to the following principles: CJ3 = ToN0Of

The acquisition of the zero speed tension reference is disabled; the tension reference selected by CJ1 parameter is always active.

CJ3 = ToN0On

When the system reaches the zero speed (see CB5 and CB6 parameters), the tension reference selected by CJ1 parameter is replaced by the value set by CJ5 parameter. The acquisition of the new value (CJ5) is filtered by a ramp programmable by the par. CJ9. When the system leaves the zero speed status, the operating tension reference is restored to the value set by CJ1 parameter. The acquisition of the new value (selected by CJ1) is filtered by a ramp programmable by the par. CJ9.

Acquisition / Calculation of the diameter

The diameter information (acquired by an external transducer or measured as line speed / angular speed ratio) is used in many of the applications listed in this chapter; it is particularly used by the Taper function and by all settings described for the calculation of the inertia compensation and for the calculation of the term related to the tension reference. These are, however, all applications requiring winding or unwinding of a given material. It is always possible to acquire the signal proportional to the diameter (0-10V) through an analog input (Ean1 or Ean2; terminals XM1- 29, 31 and XM1-30, 31). Only in applications where an axial winder is used (settings 3 and 5) it is possible to obtain the diameter information evaluating the line speed to angular speed ratio. The diameter value is always in the range defined by a minimum (CN1 parameter) and a maximum value (100%). The maximum diameter value (100%) must be related to the maximum allowed diameter of the machine. The minimum value is related to the core diameter as percent of the maximum value. Example:

Max diameter = 4m = 100% Min diameter = 0.5m = 12.5%

Note. The calculated diameter value is not stored if the SPDM converter is switched off. Function calibration External diameter transducer. Check that the transducer gives a 0V output voltage at the minimum diameter (minimum spindle without material). Check that the transducer gives a 10V output voltage at the maximum diameter allowed by the machine. Diameter calculated as line speed to angular speed ratio In minimum diameter conditions (minimum spindle without material) and reel function disabled (COM3 = OFF), check that the linear speed measured on the minimum spindle be equal to the maximum line speed, when a 100% reference is applied (Setup Reference - Cont. Speed Ref.). If this is not, adjust CB8 parameter (if CB3 = Encod) or DJ1 parameter (if CB3 = Tach) until the proper linear speed value will be reached. Diameter ramp Parameter CN5 must be set to the time value, as seconds, needed by the system to go from the minimum to the maximum diameter (winder) or vice versa (un-winder) when the line speed has its maximum value (100%). All the diameter variations greater than those allowed by the set value are filtered. Increasing sequence When the machine wind the material, the diameter must take increasing values until its maximum value (100%) will be reached at the end of the working cycle. In this case CL3 parameter will be set to Wind value; each new diameter value will be compared to the last previously acquired/calculated value and, if lower, it will be ignored. Decreasing sequence When the machine unwind the material, the diameter must take decreasing values until its minimum value (CN1) will be reached at the end of the working cycle. In this case CL3 parameter will be set to Unwind value; each new diameter value will be compared to the last previously acquired/calculated value and, if greater, it will be ignored.

Inertia compensation

Every time a speed variations is needed, the regulator must win the inertia of the load coupled to the motor. In all applications with winder or unwinder reel, the mass and as consequence the inertia of a winded/unwinded coil varies as function of the width of the coil itself, the material density and the diameter. E5.9.1

Axial winder

For proper calibration of the coil inertia compensation it is needed to set two machine acceleration times (the acceleration time can be measured according to the sequence described at par. 5.2): 1 - empty reel acceleration time (only the core cylinder without material). 2 - max reel acceleration time (max diameter, max coil width, max material density). When, because of practical reasons, the machine acceleration time measurement at max reel cannot be made, the acceleration time with a convenient coil as near as possible to the max coil can be measured. Applying the formula described at par. 8.10.3 section E, the acceleration time that would be measured in max reel conditions can be calculated. Parameters: CMA CM1 CM2

Ground Connections For personnel safety, proper operation and to reduce electromagnetic emission/pickup, the drive and the motor must be grounded at the installation site. A star ground system is acceptable although it is not the preferred method. • Conductors must be adequately sized as required by safety regulations. • Power cable shields must be connected to the drive PE terminal in order to meet safety regulations. • Power cable shields are suitable for use as equipment grounding conductors only when the shield conductors are adequately sized as required by safety regulations. • In multiple drive installations, do not connect drive terminals in series. • The panel must have a properly sized ground bus to which all system grounds are connected. The bus bar shall be connected to plant ground. • Ground connections must be as short as possible. • The drive ground connection should not be shared with other devices. • High frequency RFI requires large areas of ground bus (due to skin effect).

Floating Networks IT (ungrounded) systems: For floating networks (also known as IT, ungrounded, or impedance/resistance (greater than 30Ω ) grounded networks), if the drive is equipped with EMC filter: • Disconnect the filter before connecting the drive to an ungrounded system. • Where EMC requirements exist, check for excessive emission propagated to neighboring low voltage networks. In some cases, the natural suppression in transformers and cables is sufficient. If in doubt, use a supply transformer with static screening between the primary and secondary windings.

CAUTION!

The filter shall be grounded before applying power. The filter can only be used with balanced supply mains. Do not attempt to install or remove RFI filter connections while power is applied to the drive’s input terminals If a drive with EMC filter is installed on an IT system the system will be connected to earth potential through the EMC filter capacitors of the drive. This may cause danger or damage the unit. The filter shall not be connected to the drive output (motor side).

Unsymmetrically Grounded Networks Unsymmetrically grounded networks are defined in the following table. In such networks, the RFI filter internal connection must be disconnected.

SPDM complies with noise immunity requirements defined in EN 61 800-3 for the second enviroment and thus also with the lower noise immunity requirements in the first enviroment. The warning and installation information of this manual must be observed. Note:

a) The drive must not be equipped with the EMC filter when installed to IT (unearthed) systems. The mains becomes connected to earth potential through the EMC filter capacitors. In IT systems this may cause danger or damage the unit. b) Refer to Figure E1.3/4 for filter connection to the drive. c) RFI filter codes are in Table E1.1 and E1.2

WARNING!

The drive may cause radio interference if used in a residential or domestic environment. The user is required to take measures to prevent interference, in addition to the requirements for CE compliance listed above, if necessary.

Note: If the above listed provisions cannot be met, e.g., the drive cannot be equipped with EMC filter when installed to an IT (unearthed) network, the requirements of the EMC Directive can be met as follows for restricted distribution: 1. It is ensured that no excessive emission is propagated to neighbouring low-voltage networks. In some cases, the natural suppression in transformers and cables is sufficient. If in doubt, a supply transformer with static screening between the primary and secondary windings can be used. Medium voltage Network Supply transformer Neighbouring Network

The choke should be connected between filter and drive. Wiring the filter in the wrong sequence can damage the converter. In case a separation transformer is applied, its screen and iron core must be grounded in order utilise the filtering effect. If no static screen is present, an appropriate filter must be used.

INSTALLATION SUGGESTIONS MOUNTING PLATE AND PLACEMENT DEVICES The mounting plate must be made from steel with zinc surfaces and without any painting. It shall be connected with PE copper bar by several bolts distributed in equal distances along the bar. The RFI filter, the inputs reactors the fuses, the contactors and the drive must be placed on the mounting plate so that the connections can be made as short as possible, especially those from the drive via the input reactor to the RFI filter. The surface of the components to be mounted to the mounting plate has to be free of coating material. Components in the control cabinet (noise sources and receivers) must be physically separated, if necessary through the use of metal partitions or metal enclosures for individual components. Contactors, relays, electromechanical hours counter, solenoid valves etc in the cabinet must be provided with quenching elements (RC, diodes, varistors etc). This devices must be connected directly at the coil. CABLING The cables for digital signals which are longer than 3m and all cables for analogue signals must be screened. Each screen must be connected at both ends by metals clamps or comparable means directly on clean metal surfaces, if both earthing points belong to the same earth line. Otherwise a capacitor (10 nF-2 KV) must be connected to earth on one end. In the converter cabinet this kind of connection must be made directly on the sheet metal as close as possible to the terminals and if the cable comes from outside also on the PE bar. At the other end of the cable the screen must be well connected with the housing of the signal emitter or receiver. While grounding the shields of the cables, it is necessary to use a 360° connection and it is compulsory to avoid a pigtail connection. By pigtail is meant the connection to earth ground of the cable shield by means of an additional wire. Use a double-shielded twisted pair cable for analogue signals. This type of cable is recommended for the pulse encoder signals also. Employ one individually shielded pair for each signal. Do not use common return for different analogue signals. A double-shielded cable is the best alternative for low-voltage digital signals but single-shielded twisted multipair cable is also usable.

A double shielded twisted pair cable

A single shielded twisted multipair cable

Run analogue and digital signals in separate, shielded cables. Relay-controlled signals, providing their voltage does not exceed 48 V, can be run in the same cables as digital input signals. It is recommended that the relay-controlled signals be run as twisted pairs. Never mix 24 VDC and 115 / 230 VAC signals in the same cable. Maximum section of the control cables: 1,5mm2 (AWG16) •

Control signal cables must be kept at a distance greater than 0.3m (1 foot) from power cables. Keep both power cables and signal cables in separate raceways. If it is necessary to cross power and signal cables, cross at a 90° (right) angle.

APPENDIX E - EMC Standards and applicable Standards

POWER CABLES WITH SCREENS Power cables with screens are necessary , if they run over long distances (greater than 20 m), where they are susceptible to EMC environmental conditions. The transfer impedence ZT of the power cable must be less 0,1 Ω/m in the frequency range up to 100MHz, in order to ensure an effective reduction of emission and a significant increase of immunity. The screen must be pressed by a well conducting metal clamp directly against the mounting plate of the PE bar of converter cubicle. If it is not possible to use the shielded cables, use a pipeline/metallic raceway with a minimum covering of 80% and without interruptions, by connecting the side adjacent to the starting device to the earth bar of the panel.

LINE REACTORS Converters cause short-duration short circuits at their AC inputs, called commutation notches. The depth of this notches must be reduced if the same transformer shall supply more than one converter. In such case line reactors are necessary. They must cause about 2% relative voltage drop at rated current and are also necessary if the power of the converter is very low compared with the available power of the transformer or supply line. According to the European product standard EN 61800-3, the commutation notches must be kept below 20% of the line voltage in the first environment, whereas an upper limit of 40 % is specified for the second environment. This target can be achieved with the aid of line reactors. The inductance of these reactors to be applied in the first environment must have 4 times the value of the network inductance at the converter's connection point (point of common coupling, PCC). Due to the maximum power of public 400 V transformers (PMAX = 1.2 MVA -IMAX = 1732 A) and due to their relative short circuit voltage VSC of 4% or 6% the maximum AC current which is available for a converter is 520A or 346A (IDC ≤ 633A or 422A). With reference to EN 61800-3 the rated power of transformer must be at least 4 times the rated power of the PDS. MEDIUM-VOLTAGE LINE

Required minimum line reactor impedance for installation of converter in first environment Often the maximum current is not limited by the transformer but by the power cable to the industry region.

Additionally to the PE connections good HF connections to the ground must be realized with the aid of a mounting plate which has a well conducting surface (sheet metal from zincplated steel for example). The RFI filter, the inputs reactors and the drive must be pressed directly to the mounting plate by at least four fixing bolts, and the seating surfaces of the housings must be free from non conducting coating. The PE bar must be connected with the mounting plate by many bolts which are distributed along whole length with equal distances. All devices are connected with the PE bar by the mounting plate (and also by the PE conductors), and the PE bar is earthed via the PE conductor of the 3-phase power cable. External earth connections.

The drive shall be earthed only by the earth conductor of the line cable; an additional local earthing, especially at the motor, raises the level of the RF noise on the line cable.

PROFIBUS DP

Introduction

The exchange of useful data between a Master and several slave drives is divided into two fields that can be transmitted in each telegram: 1. process data field: command words, drive status, reference values, reading of particular process variables (speed feedbacks, armature current, armature voltage,...).In any case this type of data is read and refreshed continuously at any refresh cycle of the drive main. 2. parameter field: these are drive variables which will be stored in EEPROM, therefore, they are written as a result of a change and after being tested for consistency. As far as the reading is concerned, the system supplies the value associated to the number of decimal digits, if any, and,if necessary, with the sign. To optimise the time of Profibus bus cycle and compatibly with the task assigned to the various slaves, the user can choose a particular protocol among the five allowed ones, since each of these protocols is different according to the number of words exchanged.

F2.

General description of the protocol

In the Profibus standard, the various types of messages which can be exchanged between a Master and the various slaves are called PPO (Parameter-Process data Object) and they make up the various protocols which can be chosen by the user. Each PPO in its general form is divided into two parts: PKW and PZD. The ‘PKW’ field is used to transmit and receive the configuration parameters of the Slaves (parameter field), while ‘PZD’ contains the process operation data (process data field). Five types of PPO have been defined: PKE

F2.1

Writing and reading modes of a field parameter

For this type of parameters, the commands sent by the Master to the slave are coded in the word ‘PKE’ in the part of message related to ‘PKW’ in the following way: bit 15

bit 14 No operation Parameter reading operation Parameter writing operation Special Commands

---------> ---------> ---------> --------->

bit 1

bit 0

0 0 1 1

0 1 1 0

The second word ‘IND’ of the ‘PKW’ message contains the address of the parameter of the SPDM drive to be changed. If the user chooses a writing command parameter, the third and the fourth word in the ‘PKW’ message contain the parameter value chosen, since the SPDM drive values are all 16 bit values, the fourth word will never be used (most significant word). The parameter reading operation is a procedure similar to parameter writing. After a reading or writing command, the ‘PKW’ part of the message concerning the PPO at Master input will contain the information related to the successful, or not, execution of the sent message.

The information will be grouped as follows: The first word ‘PKE’ will contain the code of the requested operation with bit 2, if any, set to one if the previously requested operation is not allowed because a not existing parameter has been requested or because the user tried to set a value out of range: bit 15

If the parameter reading was successful, the ‘PKW’ part of the message concerning the PPO at master input, that is the second word ‘IND’ will contains the address of the parameter and the third word(‘PWE’ part) will contains the value of the parameter.
