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 IPM parameter initialization setting. The changed settings differ according to the

IPM motor specification (capacity).

Performing parameter clear or all parameter clear sets back the parameter settings to the settings required to

drive a general-purpose motor.

*1

Initial values differ according to the inverter capacity. (55K or lower/75K or higher)

*2

Setting Pr. 71 Applied motor = one of "333, 334, 8093, 8094" does not change the Pr. 71 Applied motor setting.

*3

Setting Pr. 80 Motor capacity 

 "9999" does not change the Pr. 80 Motor capacity setting.

If IPM parameter initialization is performed in rotations per minute (Pr. 998 = "3003" or "8009"), the parameters not

listed in the table above are also set and displayed in rotations per minute.
