What to do if my LiteOn EVO600021S0D2E20F Controller shows overvoltage?
- I
  isheppardAug 16, 2025
  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 Controller show undervoltage and how can I fix it?
- K
  kaylajacksonAug 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?
- Z
  zjohnsonAug 26, 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).

What causes an output phase loss in a LiteOn Controller and how do I resolve it?
- M
  Monica MedinaAug 27, 2025
  An output phase loss in your LiteOn Controller can occur if the output cable is not connected, the motor winding is impaired, the output terminal is loose, the rated current of the motor being used is 5% less than the drive rated current, an output transistor is impaired, or a single phase motor is activating. Check the wiring and properly connect the output cable. Inspect the resistance between motor lines and replace the motor if the winding is impaired. Fasten the terminal using the tightening torque specified in the manual. Check motor capacities and the drive. Note that the drive cannot run a single phase motor.

What to do if LiteOn EVO600021S0D2E20F shows PID Feedback High?
- L
  Lucas RichardsonAug 30, 2025
  If your LiteOn Controller displays a 'PID Feedback High' error, it could be due to inappropriate settings in b5-22 and b5-23, incorrect PID feedback wiring, a malfunctioning feedback sensor, or a feedback input circuit malfunction. To resolve this, confirm the b5-22 and b5-23 settings, correct the wiring, and replace the sensor if it is damaged. If the issue persists, consider replacing the PCB or drive and contact your local distributor.

What does it mean when my LiteOn EVO600021S0D2E20F Controller displays 'PID Feedback Low'?
- J
  Justin HarveySep 2, 2025
  When your LiteOn Controller displays 'PID Feedback Low', it could be due to inappropriate settings in b5-12 and b5-13, incorrect PID feedback wiring, a malfunctioning feedback sensor, or an incorrect feedback input circuit. To address this, correct the b5-12 and b5-13 settings, correct the wiring, and replace the sensor if it is damaged. If the issue continues, contact your local distributor to replace the board or the drive.

What causes overtorque detection 1 on a LiteOn EVO600021S0D2E20F?
- C
  Carrie Perez DVMSep 6, 2025
  Overtorque Detection 1 on a LiteOn Controller may be caused by incorrect parameter settings or a malfunction on the machinery. To resolve this, reset P6-01 and P6-02. Also, check the machinery and load status.

What should I do if my LiteOn EVO600021S0D2E20F Controller's heatsink temperature is over 95°C?
- L
  Laura OrtegaSep 9, 2025
  If your LiteOn Controller's heatsink temperature is over 95°C, it could be due to several reasons. The internal cooling fan might have stopped operating, or there may be bad airflow due to insufficient room. It could also be caused by high output current. To resolve this: a. Improve the airflow inside the enclosure panel. b. Install an air conditioner or fan to cool the environment. c. Remove any possible source of heat. Measure the output current and reduce the load. Lower the setting in C6-00 (Carrier Frequency Option). Replace the cooling fan if necessary.

What to do if my LiteOn EVO600021S0D2E20F Controller shows an external fault on input terminals S1 to S6?
- J
  Jesse RussellSep 12, 2025
  If your LiteOn Controller is showing an external fault on input terminals S1 to S6, it could be due to an external device tripping an alarm, incorrect wiring, or incorrect multi-function input wiring. Remove the cause of the external fault and then reset the multi-function input. Confirm if the signal lines are properly connected to the terminals assigned for external fault detection (E1-??= 23 to 38). Also, confirm if E1-??=23 to 38 is set to the unused terminals.

What causes motor overload on a LiteOn Controller and how to fix it?
- K
  Kimberly MannNov 17, 2025
  Motor overload on a LiteOn Controller can stem from several factors. The load might be too heavy, or the acceleration and deceleration times could be too short. Operating the motor below its rated speed with a high load, incorrect settings in the motor protection function, a voltage that's too high based on the V/F settings, an incorrect motor rated current setting, a base frequency set too low, running multiple motors on one drive, or mismatched electrical thermal protection characteristics could also be causes. To resolve this, check the loading capacity and reduce the load if necessary. Confirm and increase the acceleration and deceleration times using the C1-00 to C1-03 parameter settings. If operating at low speeds, reduce the load, increase the speed, or consider a higher capacity or...
