When you use the advanced magnetic flux vector control, you can perform the offline auto tuning operation to
calculate motor constants automatically.
! Offline auto tuning is made valid only when other values than "9999" are set in Pr. 80 and Pr. 81 to select
the advanced magnetic flux vector control.
! The offline tuning data (motor constants) can be copied to another inverter with the PU (FR-DU04/
FR-PU04).
! If the motor used is not Mitsubishi's standard motor (SF-JR 0.4kW or more) or Mitsubishi's constant-
torque motor (SF-JRCA 200V class 4 poles, 0.4kW to 55kW) (e.g. third party's motor, SF-JRC) or if the
wiring distance is long, you can use the offline auto tuning to run the motor with the optimum operation
characteristics.
! Offline auto tuning
Automatically measures the motor constants used for advanced magnetic flux vector control.
• Offline auto tuning can be performed with the load connected. (As the load is smaller, tuning accuracy is
higher. Tuning accuracy does not change if inertia is large.)
• For the offline auto tuning, you can select either the motor non-rotation mode or rotation mode.
Note that when making selection for the online auto tuning, the motor-only rotation mode should be
selected.
• You can read, write and copy the motor constants tuned by the offline auto tuning.
• The offline auto tuning status can be monitored with the PU (FR-DU04/FR-PU04).
