 Setting for the V/F control by selecting PM parameter initialization on the
operation panel ("PM")
• When the control method is changed from PM sensorless vector control to V/F control, all the parameter settings required to
drive an induction motor are automatically set. (Refer to
The following shows the procedure to change the control method from PM sensorless vector control to V/F control by selecting
PM parameter initialization on the operation panel.
Operating procedure
1.
Turning ON the power of the inverter
The operation panel is in the monitor mode.
2.
Changing the operation mode
Press the PU/EXT key to choose the PU operation mode.
