2.4 Adjusting the current controller
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.
Only if the unit aborts the auto-tuning routine with a fault signal FIELD REMOVAL?!
Read out values of:
41.11 = ......... 41.12 = ......... 43.02 = ......... 43.03 = ............ 43.06 = .........
15.05 = 0
El
Switch OFF power supply to the electronics section!
Make sure that no field current is flowing, e.g. by removing the supply fuses!
El
Switch the electronics section’s power supply on again!
