Offline auto tuning

The offline auto tuning enables the optimal operation of an motor.
What is offline auto tuning?
Under Advanced magnetic flux vector control, real sensor vector control or vector control operation,
measuring motor constants automatically (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 dis-
tance is long.
For the offline auto tuning for a PM motor, refer to page 5-454.

Description
Internal data converted value
The value is indicated with "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).
Use the value set in Pr. 3 "Base frequency".
Set the motor inertia.
9999: Uses the constant value of Mitsubishi
motor (SF-PR, SF-JR, SF-HR, SF-JRCA,
SF-HRCA, SF-V5RU (1500 r/min series) and
so on).
No offline auto tuning
Performs offline auto tuning without
rotating the motor
Performs offline auto tuning without
rotating the motor (V/f control, IPM motor
