PARAMETERS
PM 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.
