Matching The Thyristor Power Converter Unit To The System Conditions Concerned; Manual Balancing Of The Controllers - ABB DCS 600 MultiDrive Operating Instructions Manual

For this purpose, the following parameters at the speed controller must be adapted:
24.03 (KPS) = desired response (behaviour) of controller
24.09 (TIS) = desired response (behaviour) of controller
Only when fine-balancing of the EMF controller is wanted!
(Necessary when work as per section 2.6.3. has been performed)
For assessing control quality, the Fig. entitled "Transient response of controller"

- Link up APC or Fieldbus

2.9 Manual balancing of the controllers

Balancing of the controllers for the armature-circuit current and the field current can be
performed by auto-tuning. If this is not possible for some reason, balancing of these con-
trollers as well as balancing of the controllers for speed and EMF has to be performed
by the skilled technical start-up personnel.

- If fine-balancing of the EMF controller is wanted,
potentiometers' settings must be adapted:
17.01 (POT1) approx. 10 % bigger than speed at
field weakening point
17.02 (POT2) approx. 10% smaller than speed at
field weakening point
The following parameters at the EMF controller
must be adapted:
46.03 (EMF_KP) = desired response (behaviour) of controller
46.04 (EMF_KI) = desired response (behaviour) of controller.
