IPM parameter initialization list
●
The parameter settings in the following table are changed to the settings required to perform PM
sensorless vector control by selecting PM sensorless vector control with the IPM parameter
initialization mode on the operation panel or with Pr. 998 "PM parameter initialization".
●
Performing parameter clear or all parameter clear sets back the parameter settings to the settings
required to drive an induction motor.
