Offline auto tuning for a frequency search

V/F V/F V/F
During V/F control or when driving the IPM motor MM-EFS/MM-THE4, the accuracy of the "frequency search", which is
used to detect the motor speed for the automatic restart after instantaneous power failure and flying start, can be
improved.

The offline auto tuning automatically sets the gain
required for the frequency search.
Uses the constant value of Mitsubishi motor (SF-PR,
SF-JR, SF-HR, SF-JRCA, SF-HRCA, MM-EFS, MM-
THE4 and so on).
The offline auto tuning automatically sets the gain
required for the frequency search of the second
motor.
Uses the constant value of Mitsubishi motor (SF-PR,
SF-JR, SF-HR, SF-JRCA, SF-HRCA, MM-EFS, MM-
THE4 and so on).
No offline auto tuning.
Perform offline auto tuning for the Advanced
magnetic flux vector control. (Refer to
Performs offline auto tuning without rotating the motor
(V/F control, PM motor control (IPM motor MM-EFS/
MM-THE4)).
