Changing the motor constants (if setting motor constants in units of [Ω], [mH] or [A])
●
Set Pr. 71 as shown below.
●
Set a given value as the motor constant parameter.
For the FR-F820-02330(55K) or lower and FR-F840-01160(55K) or lower.
For the FR-F820-03160(75K) or higher and FR-F840-01800(75K) or higher.
Changing the motor constants (if setting motor constants in the internal data of the inverter)

NOTE Setting "9999" disables the tuning data. The MM-EFS/MM-THE4 constant is used for the IPM motor
MM-EFS/MM-THE4, and the inverter internal constant is used for a PM motor other than MM-EFS/
MM-THE4.
