Parameter
● This function is made valid only when a value other than "9999" is set in Pr. 80 and Pr. 81
and advanced magnetic flux vector control, real sensorless vector control or vector control
is selected.
● You can copy the offline auto tuning data (motor constants) to another inverter with the PU
(FR-DU07/FR-PU07).
● Even when motors (other manufacturer's motor, SF-JRC, SF-TH, etc.) other than Mitsubishi
standard motor, high efficiency motor (SF-JR SF-HR 0.4kW or more), Mitsubishi constant-
torque motor (SF-JRCA SF-HRCA four-pole 0.4kW to 55kW) and vector control dedicated
motor (SF-V5RU) are used or the wiring length is long, using the offline auto tuning function
runs the motor with the optimum operating characteristics.
● Tuning is enabled even when a load is connected to the motor. (As the load is lighter, tuning
accuracy is higher. Tuning accuracy does not change even if the inertia is large.)
● For the offline auto tuning, you can select either the motor non-rotation mode (Pr. 96 = "1")
or rotation mode. (Pr. 96 = "101"). The rotation mode has higher tuning accuracy than the
non-rotation mode.
● Reading/writing/copy of motor constants tuned by offline auto tuning are enabled.
● The offline auto tuning status can be monitored with the PU (FR-DU07/FR-PU07/FR-PU04).
