Initialization can be performed by setting Pr.998 IPM parameter initialization or by choosing the mode on the operation panel.
By selecting IPM motor control from the parameter setting mode or with
Pr.998 IPM parameter initialization
, the parameter
settings in the following table change to the settings required to drive an IPM motor. The changed settings differ according to
the IPM motor specification (capacity). Refer to the IPM motor specification list shown below.
Performing parameter clear or all parameter clear sets back the parameter settings to the settings required to drive a general-
purpose motor.
