(2) IPM 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 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.
*4 This parameter can be set when FR-A7NL is mounted.
*5 200r/min when Pr. 788 Low-speed range torque characteristics = "0".
*6 13.33Hz when Pr. 788 Low-speed range torque characteristics = "0".
