Initializing the parameters required to drive
an IPM motor (Pr.998) <IPM>
(2) IPM parameter initialization list
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.

(motor capacity)
*1 This parameter can be set when FR-A7NL is mounted.
When Pr.80 Motor capacity ≠ "9999," the Pr.80 Motor capacity setting is not changed by IPM parameter initialization. IPM parameter initialization is

performed by setting Pr.998 IPM parameter initialization or the parameter setting mode on the operation panel.
*3 Initial values differ according to the inverter capacity. (55K or lower/75K or higher)
REMARKS
If IPM parameter initialization is performed in rotations per minute (Pr. 998 = "1" or "12"), the parameters not listed in the table
above are also set and displayed in rotations per minute.
