For the FR-A820-03160(55K) or lower, and the FR-A840-01800(55K) or lower.
For the FR-A820-03800(75K) or higher and the FR-A840-02160(75K) or higher.
The initial value differs according to the voltage class. (200V class/400V class)
When the IPM motor MM-CF is selected by Pr. 71 "Applied motor", the rated frequency of the MM-CF
is used. When a PM motor other than the MM-CF is selected by Pr. 71, 75 Hz (for the motor capacity
15 kW or lower) or 100 Hz (18.5 kW or higher) is used.
Setting the motor capacity and the number of motor poles (Pr. 80, Pr. 81)
●
Motor specifications (the motor capacity and the number of motor poles) must be set to select
Advanced magnetic flux vector control, Real sensorless vector control or vector control.
●
