Offline auto tuning

Magnetic flux Magnetic flux Sensorless Magnetic flux
Sensorless Sensorless
The offline auto tuning enables the optimal operation of a motor.
• Under Advanced magnetic flux vector control or Real sensorless vector control, automatic measurement of motor
constants (offline auto tuning) enables optimal operation of motors even when motor constants vary, when a motor of
another company is used, or when the wiring distance is long.
For the offline auto tuning for a PM motor, refer to

By selecting a motor, the thermal characteristic and motor
constant of each motor are set.
*1
Set the applied motor capacity.
V/F control
Set the number of motor poles.
V/F control
Set the rated motor current.
Set the rated motor voltage (V).
Set the rated motor frequency (Hz).
The setting value of Pr.3 Base frequency is used.
Set the motor inertia.
9999: The constant value of Mitsubishi Electric motor (SF-PR,
SF-JR, SF-HR, SF-JRCA, SF-HRCA and so on) is used.
No offline auto tuning
Offline auto tuning is performed without the motor rotating.
Offline auto tuning is performed without the motor rotating
(under V/F control). (Refer to

Tuning data (The value measured by offline auto tuning is
automatically set.)
9999: The constant value of Mitsubishi Electric motor (SF-PR,
SF-JR, SF-HR, SF-JRCA, SF-HRCA and so on) is used.
The offline auto tuning automatically sets the gain required for
the frequency search.
The constant value of Mitsubishi Electric motor (SF-PR, SF-JR,
SF-HR, SF-JRCA, SF-HRCA and so on) is used.
