Applied Motor (Pr. 71, Pr. 450) - Mitsubishi Electric FR-E720-600 Instruction Manual

4.9.2

Applied motor (Pr. 71, Pr. 450)

Setting of the used motor selects the thermal characteristic appropriate for the motor.
Setting is required to use a constant-torque motor. Thermal characteristic of the electronic thermal relay function
suitable for the motor is set.
When general-purpose magnetic flux vector or advanced magnetic flux vector control is selected, the motor constants
(SF-JR, SF-HR, SF-JRCA, SF-HRCA, etc.) necessary for control are selected as well.

REMARKS
When performing offline auto tuning, set any of "3, 13, 23, 43, 53" in Pr. 71.
(Refer to page 113 for offline auto tuning.)
For the FR-E720-240 and 330, FR-E740-120 and 170, the Pr. 0 Torque boost and Pr. 12 DC injection brake operation voltage
settings are automatically changed according to the Pr. 71 setting as follows.
