5.10.3 Offline auto tuning for a PM motor (motor constants
tuning)
The offline auto tuning for a PM motor enables the optimal operation of a PM motor.
• Automatic measurement of motor constants (offline auto tuning) enables optimal operation of motors for PM motor control
even when motor constants vary or when the wiring distance is long.
For the offline auto tuning under Advanced magnetic flux vector control, refer to page 353.
