14.3 Offline auto tuning for a PM motor (motor constant tuning)
14.3
Offline auto tuning for a PM motor (motor constant
tuning)
The offline auto tuning enables the optimal operation of a PM motor.
• Automatic measurement of motor constants (offline auto tuning) enables optimal operation of motors for PM sensorless
vector control even when motor constants vary or when the wiring distance is long.
For the offline auto tuning under Advanced magnetic flux vector control, Real sensorless vector control, and Vector control,
