Mitsubishi Electric FR-A720-0.4K Instruction Manual page 509

1.4 Applied motor (Pr. 71)
Setting of the used motor selects the thermal characteristic appropriate for the motor.
Setting is necessary when using a constant-torque motor. Thermal characteristic of the electronic
thermal relay function suitable for the motor is set.
When PM sensorless vector control is selected, the motor constants (MM-CF etc.) necessary for control
are selected as well.
