Cause : Over current comes when the output current exceeds the overcurrent detection level. Inspect the machine to see if it's stuck or bound in some way, preventing the motor from turning.

  1. Check motor insulation and connection.
  2. Increase acceleration and deceleration rates.
  3. Check feedback devices.
  4. Check motor cable length.
