Applied Motor (Pr. 71, Pr. 450) - Mitsubishi Electric FR-A700 Instruction Manual

Selection and protection of a motor
6.12.2

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..
