5.10.2 Offline auto tuning
The offline auto tuning enables the optimal operation of an motor.
• Under Advanced magnetic flux vector control, automatic measurement of motor constants (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 363.
