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.

Note: use online mode in DriveWindow

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

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

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.

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.

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 autotuning routine. If necessary, perform manual balancing.

DCF converter 15.21 = ? DCS converter 15.05 = ?

15.22 = ? 41.03 = ? (for display purpose)

46.07 = ?

Note: The field current control parameters of the armature converter (44.02, 44.08, ...)

are not used.

Make sure that static current limitation Bridge 1 (20.12) and Bridge 2 (20.13; with

4Q-unit) have been set to the same value; values of all parameters for current

reference limitation must be bigger than 20 %; conditions have been satisfied if

default setting has been taken as starting point; setting to maximally required motor

current is recommended.

Drive must not turn! Do not preset an external reference!

15.02 = 3

Activate the current controller’s auto-tuning function.

Start the next two steps within the next 20 seconds!

Switch ON power.

DANGER: System components now energized!

Start drive.

When the display shows ”0” (zero) stop drive; it may happen that the unit runs

armature-circuit current since EMF control is active.

Note: use online mode in DriveWindow

Switch OFF power!

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, missing field contactor

etc.).

Afterwards repeat the auto-tuning routine.

If necessary, perform manual balancing.
