3.29.2.9 Motor model
P1750[3] Control word of motor model Min: 0
CStat: CUT Datatype: U16 Unit: - Def: 0
P-Group: CONTROL Active: first confirm QuickComm.: No Max: 3
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.
