Adjusting the current controller | DCS 500 specification

Chapter 2 - Start-Up 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; nmin - 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-1field 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!
