6.5.11 Controller structure
6.5.12 Current Control
(Torque Control)
The current control consists of two standard PI-controller.
• Active current controller (torque controller) dS.0, dS.1 with
speed-dependent precontrol dS.9
• Magnetizing current controller dS.5, dS.6
The basic setting of the controller is done automatically through the motor adaption
Fr.10 (see Chapter 6.5.3).
If in the individual case a fine adjustment should be necessary the proportional gain
factor can be adjusted with dS.0 and dS.5. The integral factor is adjusted with dS.1
and dS.6. The precontrol of the active current controller can be changed by means of
dS.9.
With ds.5 and dS.6 = „0“ the values for the active current controller become effective
for the magnetizing controller too (standard setting).
