Offline auto tuning for a PM motor (motor
constants tuning)
The offline auto tuning for an PM motor enables the optimal operation of a PM motor.
• What is offline auto tuning?
Automatic setting of motor constants necessary for operation under PM sensorless vector control (offline auto tuning)
enables optimal operation of PM motors.
For the offline auto tuning under Advanced magnetic flux vector control, Real sensorless vector control, and vector
control, refer to
page 426 .
