The motor performance can be maximized with offline auto tuning.
What is offline auto tuning?
●
When performing advanced magnetic flux vector control, real sensorless vector control or
vector control, the motor can be run with the optimum operating characteristics by automa-
ticaly measuring the motor constants (offline auto tuning) even when each motor constants
differs, other manufacturer's motor is used, or the wiring length is long.
