Selection and protection of a motor
4.8.3
To exhibit the best performance of the motor performance (offline auto tuning)
(Pr. 71, Pr. 80, Pr. 82 to Pr. 84, Pr. 90, Pr. 96)
The above parameters can be set when
Pr. 160 Extended function display selection
= "0".
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 wiring length is long.
