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

If the unit aborts the auto-tuning routine with the signal 15.02 = -1, the probable

cause of this can be read out of Parameter 6.02 and has to be eliminated as far

as possible (supply, switching sequence, field contactor wiring etc.).

Afterwards repeat the auto-tuning routine.

If necessary, perform manual balancing.

Switch OFF power!

 Continue with Chapter 2.4

Only for DCS 600 converters connected to DCF 601 or DCF 602 field supply unit

15.05= 2

41.03 = Rated motor field current (first field exciter) has already been set.

44.17= Field current (first field exciter) for "Under-excitation" signal

Switch OFF power!

Before adjustment of the armature-circuit power converter is continued

(Chapters 2.4 etc.), first perform the start-up routine for the DCF 601 or

DCF 602 field supply unit.

Make sure the correct wiring between 3-phase Field exciter DCF 601, DCF 602 and the

overvoltage protection unit DCF 505, DCF 506

• powercircuit

• Digital feedback signal of DCF 506

El Switch ON DCF 601, DCF 602.

DANGER: System components now energized!

15.16 = 5 (Field Exc)

99.02 = 02 Rated motor field voltage

99.03 = 03 Rated motor field current

(same as in 41.03 of DCS armature converter)

50.03 = 4

43.13 = 4 or higher (Bridge reversal time)

43.06 = 0

28.22 = 500% (disable overvoltage monitoring)

Switch ON DCF 601, DCF 602.

check field current and field voltage by measuring them

Disable reference

15.02= 5 (start autotuning current controller)

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

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

display.
