What to do if my LiteOn EVO600021SD75E20F shows overvoltage?
- D

  If your LiteOn Controller is showing an overvoltage error, it could be due to several reasons. There might be a surge voltage entering the drive input power, possibly from a thyristor convertor or phase advancing capacitor. A short circuit in the machinery output or a ground fault in the output circuit could also cause the DC bus capacitor to overcharge. Additionally, electrical signal interference might be causing the drive to malfunction. To address this, consider installing a DC link choke, inspect the motor power cable, relay terminals, and motor terminal box. Correct any grounding shorts and reapply power. You may also need to check the solutions for interference suppression, focusing on the control circuit lines.

Why does my LiteOn EVO600021SD75E20F Controller show undervoltage and how can I fix it?
- S
  Shelly SmithAug 22, 2025
  An undervoltage error on your LiteOn Controller may be due to several reasons: a loss of input power phase, loose wiring terminals on the drive input power, a problem with the voltage from the drive input power, weakened drive main circuit capacitors, or damage to the contactor or relay on the soft-charge bypass circuit. To troubleshoot, first, correct the drive input power wiring and tighten the terminals. Check the voltage and adjust it according to the drive input power specifications, and inspect the main circuit magnetic contactor. If the problem persists, try turning the power on and off to see if any issues occur. If the problem continues, consider replacing the entire drive or the control board.

What causes a LiteOn Controller to display a motor overheat error?
- D
  Dalton ShafferAug 25, 2025
  A motor overheat error on your LiteOn Controller can be caused by a fault on the machinery, such as the machinery being locked up, or simply the motor overheating. To resolve this, first check the machinery status. Then, check the load, acceleration/deceleration time, and cycle time. You can reduce the load, increase the C1-00 to C1-07 (Acc./Dec. Time) settings, and adjust d1-02 to d1-11 (V/F Characteristics).
