Simple mode parameter list
5.1.8 To exhibit the best performance of the motor performance
(offline auto tuning) (Pr. 9, Pr. 71, Pr. 80, Pr. 82 to Pr. 84, Pr. 90, Pr. 96)
The motor performance can be maximized with offline auto tuning.
What is offline auto tuning?
When performing general-purpose magnetic flux vector control, the motor can be run with the
optimum operating characteristics by automatically measuring the motor constants (offline auto
tuning) even when each motor constants differs, other manufacturer's motor is used, or the wir-
ing length is long.
