POINT
· 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).
· Do not connect a surge voltage suppression filter (FR-ASF-H) to the 01800 or less and sine wave filter (MT-BSL/BSC) to
the 02160 or more between the inverter and motor.
