4.2.26 Applied motor (Pr. 71)
Pr. 71 "applied motor"
Set the motor used.
y 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 overcurrent protection is set to the thermal characteristic of the
constant-torque motor.
