Chapter 2 - Start-Up Instructions
IV A 2 - 10 DCS 500B / DCP 500B Operating Instructions
2.4 Adjusting the current controller
Make sure that static current limitation Bridge 1 (2307) and Bridge 2 (2308; with
4Q-unit) have been set to the same value; values of all parameters for current
reference limitation must be greater 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!
1201 = 3 Panel display: ARM. AUTOTUNING
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 NOT ACTIVATED (action correctly completed), stop drive;
it may happen that the unit runs armature-circuit current since e.m.f. control is active;
n
min
- signal (2201) ⇒ value too small.
Switch OFF power!
If the unit aborts the auto-tuning routine with a fault signal, then eliminate
cause of this as far as possible (supply, switching sequence, etc.; see also
description for 11201), then repeat the above points, or continue with next point.
Read out values of:
407 = ............ 408 = ............ 409 = ............ 410 = ............ 411 = ............
Only if the unit aborts the auto-tuning routine with a fault signal FIELD REMOVAL?!
505 = 0 Panel display: NO FIELD EXCITER
11202 = SAVE MOT1 SET
Save the altered values in the non-volatile memory!
Switch OFF power supply to the electronics section!
If the SDCS-FEX-1 field supply is being used:
make sure that no field current is flowing, e.g.
by removing the supply fuses!
Switch the electronics section's power supply on again!
