Selection and protection of a motor

PARAMETERS
4.13.2 Applied motor (Pr. 71, Pr. 450)
(1) Set the motor to be used
Refer to the following list and set this parameter according to the motor used.
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 advanced magnetic flux vector, real sensorless vector control or vector control is selected, the motor
constants (SF-JR, SF-HR, SF-JRCA, SF-HRCA, SF-V5RU) necessary for control are selected as well.
