Tab. 5-193: Parameter setting ranges
For the FR-A820-03160(55K) or lower and FR-A840-01800(55K)or lower.
For the FR-A820-03800(75K) or higher and FR-A840-02160(75K)or higher.
NOTE Setting "9999" disables the tuning data. The MM-CF constant is used for the IPM motor MM-CF,
and the inverter internal constant is used for a PM motor other than MM-CF.
Changing the motor constant (if setting motor constants in the internal data of the inverter)
