*1 For the 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.
*2 For the FR-A820-03160(55K) or lower, and FR-A840-01800(55K) or lower.
*3 For the FR-A820-03800(75K) or higher, and FR-A840-02160(75K) or higher.
*4 The initial value differs according to the voltage class (200 V / 400 V).
*5 The setting range and unit change according to the Pr.71 (Pr.450) setting.
• The settings are valid under 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 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 using the operation panel.
• The offline auto tuning status can be monitored on the operation panel or the parameter unit.
 Before performing offline auto tuning
Check the following points before performing offline auto tuning:
• Check that PM sensorless vector control is selected.
• Check that a motor is connected. (Check that the motor is not rotated by an external force during tuning.)

9999: The MM-CF constant is used when the IPM motor MM-
CF is selected, and the inverter internal data is used when a PM
motor other than MM-CF is selected.
Set the maximum current (OCT) level of the second motor.
The MM-CF constant is used when the IPM motor MM-CF is
selected, and 200% when a PM motor other than MM-CF is
selected.
