Why my Oriental motor Controller motor does not rotate?

  Katherine PhillipsAug 2, 2025
  If your Oriental motor Controller's motor isn't rotating, there are several potential causes. First, ensure that either the FWD or REV input is turned ON, as both being OFF will prevent rotation. Next, confirm that the operation data includes a set rotation speed. The motor will not rotate if this is not set. If using an external speed setter, verify that the 'external speed command input' parameter is set to 'ON (Enable).' Also, check the connections of the AC power supply, motor, and capacitor. Finally, ensure that the FREE input is turned OFF.

  If the speed of your Oriental motor Controller cannot be changed or the motor isn't rotating at the set speed, check if the operation data selection input is switched correctly using the M0 and M1 inputs. If using an external speed setter, ensure both M0 and M1 inputs are turned OFF, and that the 'external speed command input' parameter is set to 'ON (Enable).' Also, verify the settings for the 'speed upper limit' and 'speed lower limit' parameters, as the rotation speed range might be limited.

Why Oriental motor DSC motor doesn't start instantaneously?

  If your Oriental motor Controller's motor doesn't start instantaneously, the acceleration time might be too long; try adjusting it. Also, the load inertia or the load itself might be excessive, so reduce them accordingly.

How to fix reversed rotation direction on Oriental motor Controller?
- H

  If your Oriental motor Controller's motor rotates in the opposite direction, first check the connections of the FWD and REV inputs to ensure they are correct. If you're using a gearhead that rotates in the opposite direction to the motor, reverse the FWD and REV input operations. Also, verify the setting for the 'motor rotation direction' parameter and change it if necessary.

Why Oriental motor DSC Controller motor rotates without speed command?
- S
  Stephanie MirandaAug 22, 2025
  If your Oriental motor Controller's motor rotates even without a speed command, the 'speed lower limit' parameter might have a value set. Set the value in the 'speed lower limit' parameter to '0'.
