
For FR-A820-00077(0.75K) or lower and FR-A840-00038(0.75K) or lower, it is set to 85% of the inverter rated current.

For the FR-A820-03160(55K) or lower and FR-A840-01800(55K) or lower.

For the FR-A820-03800(75K) or higher and FR-A840-02160(75K) or higher.

Differs according to the voltage class. (200 V/400 V)

The setting range and unit change according to the Pr.71 (Pr.450) setting.
POINT POINT
• The settings are valid under the PM sensorless vector control.
• The offline auto tuning enables the operation with SPM motors and IPM motors other than MM-CF. (When a PM motor other
than the IPM motor MM-CF is used, always perform the offline auto tuning.)
• Tuning is enabled even when a load is connected to the motor.
• Reading/writing of the motor constants tuned by offline auto tuning are enabled. The offline auto tuning data (motor
constants) can be copied to another inverter with the operation panel.
• The offline auto tuning status can be monitored with the operation panel and the parameter unit.
