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

Different coded applications are handled and supported from local ABB organizations.

The software of the units series DCS 600 is divided into two parts which are handled

by processors integrated in the respective boards SDCS-CON-2 (Software 15.2xx) and

SDCS-AMC-DC (Software 15.6xx).

The upload of signals from SDCS-CON-2 to SDCS-AMC-DC board are operated by:

• 6 automatic channels

• 11 programmable channels, selectable in group 94 (see Software description - chapter

31)

The 6 automatic channels are used by the functions:

• Display signals at control panel CDP 312

• Monitor signals at DriveWindow Tool

• Data Logger at DriveWindow Tool

If

• more than 6 signals of the SDCS-CON-2 board are selected, or

• the function Signals and Parameter of DriveWindow, or

• the overriding control (AC 80, AC 70…)

is used for monitoring, the signals should be selected in group 94.xx

Note: In the below mentioned tables AMC / CON-2 will be used as type designations

instead of SDCS-AMC-DC / SDCS-CON-2.

• Fixed (defined) values

Cyclic transmission is used for fixed values. Fixed values are:

other values every 8 ms:

Symbols for switching the electronics or the power section ON and OFF

Check the unit for damage in transit or other damage.

Install and wire unit; connect all inputs and outputs required.

Proceed in the same way for the field supply unit as well.

Check whether protective measures, earthing, screening, etc. have been taken in

accordance with the system conditions involved.

Check the rated value of the supply voltage for the electronics and the fan:

• matching transformer necessary when:

- 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
