PARAMETERS
When you use the advanced magnetic flux vector control, you can perform the offline auto tuning operation
to calculate motor constants automatically.
z Offline auto tuning is made valid only when values other than "9999" are set in Pr. 80 and Pr. 81 to select
the advanced magnetic flux vector control.
z The online tuning data (motor constants) can be copied to another inverter with the PU (FR-DU04/FR-
PU04).
z If the motor used is not the Mitsubishi standard motor (SF-JR 0.4kW or more) or Mitsubishi constant-
torque motor (SF-JRCA 200V class 4 poles, 0.4kW to 55kW) (e.g. other manufacturer’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.
z 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).
* The inverter of 400V voltage class is factory-set to 400V.
