  Ms. Tonya Mann DDSAug 18, 2025
  The Oriental motor Controller might rotate in the opposite direction because the rotation direction switch is set to the wrong side. Another reason could be the usage of a gearhead that rotates in the opposite direction. Finally, if using external signals, the FWD and REV inputs might be connected incorrectly or improperly. Check these connections to resolve the issue.
