For FR-A860-00027, it is set to 85% of the inverter rated current.
For the FR-A860-01080 or lower.
For the FR-A860-01440 or higher.
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. (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.
