Field-orientated vector control

P1400[3]

Configuration of speed control

CStat: CUT
P-Group: CONTROL
Configuration for speed control.
Bitfields:
Bit00 Automatic Kp adaption
Bit01 Integral freeze (SLVC)
Index:
P1400[0] : 1st. Drive data set (DDS)
P1400[1] : 2nd. Drive data set (DDS)
P1400[2] : 3rd. Drive data set (DDS)
Note:
P1400 Bit 00 = 1:
Automatic gain adaption of speed controller is enabled. In the area of field weakening the gain is reduced in
dependence on flux.
Kp
P1400 Bit01 = 1:
The integrator of the speed controller is frozen if Sensorless Vector Control (SLVC) is selected and the
control is switched from closed-loop to open-loop operation.
Advantage:
The correct amount of slip compensation is calculated and applied to the open-loop function for a motor
under load.
