Cause : Overload signal detection comes when the current limit function of the converter is activated. Check that the acceleration/deceleration time set in the inverter is not too short.

  1. Check that the load is not too heavy.
  2. Check for any failures in peripheral devices.
  3. Set the acceleration/deceleration time longer in the inverter.
  4. Reduce the load.
