5.10.2 Offline auto tuning

Magnetic flux
Magnetic flux
Magnetic flux
The offline auto tuning enables the optimal operation of a motor.
• Under Advanced magnetic flux 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

Internal data converted value
The value is indicated in A, Ω, mH, or %.
By selecting a motor, the thermal characteristic and motor
constant of each motor are set.
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-JR,
SF-HR, SF-JRCA, or 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 (V/F
control, IPM motor MM-EFS/MM-THE4). (Refer to
