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

to another location, care must be taken to ensure that the environmental conditions are complied with (see "System Description

DCS 600").

Rating plate For purposes of identification, each thyristor power converter is fitted with rating plates, stating the type code and the serial number,

which serve for each unit’s individual identification.

The type code contains information on the characteristics and the

configuration of the unit. The first three digits of the serial number

refer to the year and week of manufacture. The last digits complete

the serial number so as to preclude two units receiving the same

type code and the same serial number.

The group 4 provides information on the unit’s software configuration.

The technical data and specifications are valid as of going to press.

ABB reserves the right to make subsequent alterations.

If you have any questions concerning your drive system, please

contact your local ABB agent.

CAUTION: it is absolutely essential that the applicable accident prevention

regulations be observed by the user (in this context, please also

read the chapter entitled "Safety Instructions")!

How this chapter is structured

For better understanding the individual steps of start-up work are distinguished by

a) frames without any additional marking on the left side:

These steps of start-up work must always be performed (= mandatory start-up work)!

Example:

42.06 = Rated line voltage

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

b) frames with marking on the left side (“columns” shaded in grey):

These steps of start-up work have to be performed only when the condition stated

(as heading) applies to the selected drive configuration! After this work has been

completed, the mandatory start-up work has to be continued.

Example:

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

42.07 = Rated power converter current

Recommended motor voltages and field voltages

• Motor voltage UA when the following units are used

DCS 601: UAmax = Line voltage * 1.16 (2- quadrant unit)

DCS 602: UAmax = Line voltage * 1.05 (4- quadrant unit)

• Field voltage UF (= max. output voltage) when the following is being used

SDCS-FEX-1: UF = Line voltage * 0.9

If there is a divergence of more than 10 % between the field supply unit’s output

voltage and the rated field voltage UFrated stated on the motor’s rating plate, then the

connecting voltage UN should be reduced, using a matching transformer or a series

resistor Rv: Rv = (0.9 * UN - UF) / IF IF = Rated field current

(Note: also suitable for fine-balancing the maximum motor voltage)

• Field voltage UF when the following is being used

SDCS-FEX-2 /

DCF 503 / DCF 504: UF = Line voltage * 0.6 ... 0.8

• Field voltage UF when the following is being used

DCF 601: UF = Line voltage * 0.5 ... 1.1

Maximally possible output voltage UAmax using

DCF 601 / DCF 602: UAmax = Line voltage * 1.35

Phase sequence when connecting to the mains / Potential isolation

No special phase sequence required for the main connections U1, V1 and W1!

Phase coordination between electronics section and power section not necessary!

For potential isolation and for avoiding ground loops, an isolating transformer should be

installed upstream when an oscilloscope is being used.

Preventing unintended operating states / Shutting the drive down

CAUTION! As laid down in DIN 57100 Part 727 / VDE 0100 Part 727 (Preventing

unintended operating states), shutting the drive down by means of the

signals at the binary inputs DIx is not sufficient in itself as the sole

measure involved for avoiding unintended operating states or shutting

the drive down in the event of danger!

Range of application for the Start-Up Instructions

The Start-Up Instructions are referenced to the parameter settings in their as-delivered

condition (default values) and to the unit wiring as shown in the connection diagram

(see System description DCS 600).

These Operating Instructions only describe the start-up procedure via panel CDP 312

when in LOCAL mode or/and via PC program DRIVES WINDOW.

Method of functioning of the binary input DI5

• Binary input DI5; designation EM STOP

The binary input DI5, e.g. terminal X6:5 of control board SDCS-CON-2, must be

set to logical "1” in order to get no operation of the EMERGENCY STOP function.

This configuration takes into account the requirements of a fail-safe-circuit.

The incoming signal is inverted by means of the Parameter 13.12 thus setting the

internal signal EMERGENCY STOP to logical "0”. If the external signal is "0”,the

EMERGENCY STOP function will be active and the alarm signal A 102 will appear.

The drive will react in accordance with the setting of Parameter 21.04 EME_STOP_

MODE (presetting is: 1 = STOP WITH RAMP). The ramp time is set by Parameter 22.04. After resetting of the signal, i.e. external signal set back to

logical "1”, the ON command has to be repeated.

Software identification

The software identification of the SDCS-CON2 board is in parameter 4.11.

The software identification of the SDCS-AMC-DC board is in parameter 4.2.

The application identification from ABB Lampertheim is [DCS600xx] in parameter 4.3.
