Motor model

P1750[3]

Control word of motor model

CStat: CUT
P-Group: CONTROL
Control word of motor model. This parameter controls the operation of the sensorless vector control (SLVC)
at very low frequencies. This therefore includes the following conditions:
- Operation directly after an ON command
- zero crossing.
