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!

42.07 = Rated power converter current

Enter numerical value from rating plate here

42.08 = Rated power converter supply voltage / coding of voltage

 measurement (see technical data 5-12)

Enter numerical value from rating plate here

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

set in the parameter with that obtaining at the power section.

If the unit outputs the "Phase sequence fault of power section” signal (F 38 PHAS

SEQU):

- switch off unit completely and disconnect from the mains, interchange two phases

at the input, and start again from the beginning of this chapter.

or

- enter: 42.01 = R-T-S and then acknowledge fault signal.

Unit will automatically adapt to phase sequence; this signal is to be interpreted as

information to the effect that the fans' direction of rotation may be wrong for size-C3

or size-C4 units (observe direction of arrow on the fan).

Only for uncontrolled field supply with SDCS-FEX-1!

15.05 = 1

Check field current and field voltage by measuring them.

Switch OFF power!

 Continue with Chapter 2.4

Only for controlled field supply with SDCS-FEX-2 or DCF 503/DCF 504!

15.05= 2

41.03 = Rated motor field current has already been set

44.17= Field current for "Under-excitation" signal

Check field current and field voltage by measuring them;

if necessary, correct field current with 41.03.

15.02 = 5

Activates the field current controller’s auto-tuning function.

Action has been completed when ”0” (zero) is shown on the

display.
