Selection and protection of a motor
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).
If any other manufacturer's motor is 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).
