 PM parameter initialization list
• The parameter settings in the following table are changed to the settings required to perform PM motor control by selecting
PM motor 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.
