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 If "9999" is set, tuning data will be invalid and the constant values for Mitsubishi motors (SF-PR,
SF-JR, SF-HR, SF-JRCA, SF-HRCA and SF-V5RU (1500 r/min series) and so on) are used.
Changing the motor constant (if setting motor constants in the internal data of the inverter)
● Set Pr. 71 as follows.
Motor
Mitsubishi standard motor
Mitsubishi high-efficiency motor
Mitsubishi constant-torque motor
Mitsubishi high-performance energy-
saving motor
Vector control dedicated motor
Other manufacturer's standard motor
Other manufacturer's constant-torque
