ABBDCS Thyristor Power Converters for DC Drive Systems 25 to 5150 A Operating Instructions DCS 600 MultiDrive

- electronics supply is not equal to 115 V/230 V

- single-phase-fan supply is not equal to 230 V

- three-phase-fan supply is not within the range of 400 V .... 690 V (star/delta

connection).

Check the rated value of the supply voltage for the armature-circuit converter’s

power section; the particulars given on the rating plate must be > than the rated

line voltage.

If this condition is not satisfied, then the following applies:

- use an isolating transformer, or

- use a suitable unit.

Check the rated value of the supply voltage for the field supply unit.

(Particulars on rating plate > rated line voltage?

Is an auxiliary transformer or perhaps a series resistor necessary?)

Check the wiring, fusing, the cross-sectional areas of the cables.

Check the system’s EMERGENCY STOP for proper functioning! Set the system-side

monitoring functions, and activate them. Check whether auxiliaries, such as motor fans

or unit fans, function properly; while doing this, also check for correct direction of rotation and voltage level as well!

2.2 Scaling intra-unit signals

Make sure that the existing electronics supply voltage has been set on the SDCSPOW-1 power supply board as well, using the SW1 switch.

If an encoder is being used as the speed feedback device, make sure that the correct

supply voltage has been set on the boards

SDCS-POW-1: ⇒ X3: / X4: / X5: SDCS-IOB-3: ⇒ S4

El Switch on the power supply to the electronics section.

The display of the Control Panel CDP 312 / DRIVES WINDOW may show a

fault or an alarm signal or the seven segment display may indicate an error code

as a sequence of characters and digits.

NOTE: For Software downloading observe the relevant instructions

given on the ”read_me” file of the corresponding Software disc!

Set this only for units with a rated current 25 ... 2000A in case of control board

exchange!

15.02 = 22

After successful saving of the altered data this Parameter 15.02 will be

reset to zero.

Set this only for units with a rated current ≥ 2050A in case of control board

exchange!

42.09 = 45 degrees Celsius

Temperature monitoring of power section

42.10 = C4 ⇒ Size C4 has been selected

Coding for unit type

42.11 = 1 : Single bridge (2-Q) converter ⇒ on rating plate: DCS 601 xxxx

4 : Double bridge (4-Q) converter⇒ on rating plate: DCS 602 xxxx

Coding for power section (bridge) type

CAUTION! Please don't forget!

Save the altered data of unit type, i.e. Parameters 42.07 ... 42.11:

15.02 = 22

After successful saving of the altered data this Parameter 15.02 will be

reset to zero.

Presetting of the EMERGENCY STOP function via binary input DI5:

Connection of this signal has to correspond with the configuration of a fail-safecircuit, i.e. if the signal applied to DI5 is "0” (parameter 12.16 EME STOP SEL is set to

DI5), the EMERGENCY STOP function will operate (will be activated).

13.12 = INVERTED

Inverting the incoming signals

21.04 = e.g. COAST STOP

The drive will coast to stop with this setting

22.04 = e.g. 1 ⇒ 1 sec

Setting of the ramp time with EMERGENCY STOP function provided that the

Parameter 21.04 = RAMP STOP has been selected

Input of data concerning the connected I/O boards:

98.08 = Make settings which correspond to the hardware configuration used.

Input of data is necessary as the software will check the availability of the I/O

bords as specified by settings.

Input of motor data and line voltage:

41.03 = Rated motor field current

Max. field current of the motor as indicated on rating plate. This is used to scale

those parameters referring to the motor field current, such as field current limitation

and field current monitoring.

42.06 = Rated line voltage

This is used to scale those parameters referring to the line voltage, such as line

undervoltage.

99.02 = Rated motor voltage

Scaling speed for speed control with EMF feedback.

99.03 = Rated motor current

This is used to scale those parameters referring to the rated motor current, such

as current limitation or torque limitation.

99.05 = Speed at field weakening point

Maximum speed of motor within armature control range and flux control.

Scaling speed for speed control with EMF feedback.

Note: Calculation of the nominal torque 4.22 is based on this parameter.

41.19 = Int EMF REF

Reference for voltage control in field weakening range.

50.01 = Speed scaling

Speed of the motor to be scaled to 20 000.

This scaling is used for overriding control and for internal dataprocessing, i.e.

scaling of the speed dependent parameters, such as min. and max. values.

Note 1: The Speed scaling must be set in the range of 87%…500% of the motor nominal speed (99.05).

Note 2: The Software DRIVES WINDOW and the Control Panel CDP 312 will

always display physical units!

2.3 Presetting the field supply unit

Make sure that existing supply voltages for power section, field supply unit (field

exciter) and field winding, fan, etc. match the rated data of the components used.

Switch ON power.

DANGER: System components now energized!

Please wait a few moments. During this time, the unit compares the phase sequence
