Offline auto tuning
The offline auto tuning enables the optimal operation of an motor.
• What is offline auto tuning?
Under Advanced magnetic flux vector control, real sensor vector control or vector control operation, measuring motor
constants automatically (offline auto tuning) enables optimal operation of motors even when motor constants vary,
when a motor of another company is used or when the wiring distance is long.
For the offline auto tuning for a PM motor, refer to page 436 .
