Applied Motor (Pr. 71) - Mitsubishi Electric FR-E520 Instruction Manual

4.2.26 Applied motor (Pr. 71)

Pr. 71 "applied motor"
Set the motor used.
• When using the Mitsubishi constant-
torque motor, set "1" in Pr. 71 for either
V/F control or general-purpose
magnetic flux vector control.
The electronic thermal relay function is
set to the thermal characteristic of the constant-torque motor.
• When you selected the Mitsubishi constant-torque motor, the values of the following
parameters are automatically changed. (only for the factory setting value)
Pr. 0 "torque boost", Pr. 12 "DC injection brake voltage"

By setting any of "100 to 123", thermal characteristic of electronic thermal relay function
(applied motor) can be changed as indicated below according to the ON/OFF status of
the RT signal:
