*1 For the FR-F860-00680 or lower.
*2 For the FR-F860-01080 or higher.
*3 The setting range and unit change according to the Pr.71 (Pr.450) setting.
• The settings are valid under the PM motor control.
• The offline auto tuning enables the operation with SPM motors and IPM motors. (When a PM motor 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.
