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 FR-A720-02150 (FR-A740-01100) or less and sine
wave filter (MT-BSL/BSC) to the FR-A720-02880 (FR-A740-01440) or more between the inverter and motor.
