Exhibiting The Best Performance For The Motor (Offline Auto Tuning) (Pr. 71, Pr. 80 To Pr. 84, Pr. 90 To Pr. 94, Pr. 96, Pr. 859) - Mitsubishi Electric FR-E720-0.1KNC Instruction Manual

5.11.3 Exhibiting the best performance for the motor (offline auto tuning)
(Pr. 71, Pr. 80 to Pr. 84, Pr. 90 to Pr. 94, Pr. 96, Pr. 859)
The motor performance can be maximized with offline auto tuning.
What is offline auto tuning?
When performing Advanced magnetic flux vector control or 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 wiring length is long (30m
or more as a reference).
