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.

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.
