What to do if LiteOn EVO 6800 shows motor overload?
- K
  Karen WillisSep 10, 2025
  If your LiteOn DC drive is showing a motor overload, check the loading capacity and reduce the load if necessary. Also, confirm the acceleration and deceleration times and increase C1-00 to C1-07 if they are too short.

What to do if my LiteOn DC Drives motor overheats?
- S
  Steven HernandezAug 25, 2025
  If your LiteOn DC Drives motor is overheating, it could be due to: * Incorrect wiring for the motor temperature input (terminal MT). * A fault in the machinery (e.g., machinery is locked up). * Motor overheat. To address this: 1. Correct the wiring for terminal MT. 2. Check the machinery status. 3. Check the load, acceleration/deceleration time, and cycle time: * Reduce the load. * Increase the C1-00 to C1-07 (Acc./Dec. Time) settings. * Adjust d1-02 to d1-11 (V/F Characteristics).

What causes External Fault ( Input Terminal S1 to S7 ) in LiteOn EVO 6800 and how to fix it?
- C
  Chad AllenAug 27, 2025
  An external fault in LiteOn DC Drives, indicated by Input Terminal S1 to S7, can be caused by: * An external device tripping an alarm. * Incorrect wiring. * Incorrect multi-function input wiring. To resolve this: 1. Remove the cause of the external fault, then reset the multi-function input. 2. Confirm the signal lines are properly connected to the terminals assigned for external fault detection (E1-??= 23 to 38). 3. Confirm if E1-??=23 to 38 is set to the unused terminals.

What causes Undervoltage in LiteOn DC Drives?
- D
  David GuerreroAug 27, 2025
  Undervoltage in LiteOn DC Drives can stem from: * Input power phase loss. * Loose wiring terminals of drive input power. * A problem with the voltage from the drive input power. * Weakened drive main circuit capacitors. * Damage to the contactor or relay on the soft-charge bypass circuit. To troubleshoot: 1. Correct the drive input power wiring. 2. Tighten the terminals. 3. Check the voltage: * Adjust the voltage according to the drive input power specifications. * Check the main circuit magnetic contactor if there is no problem with the power supply. 4&5. If problems persist after power cycling, consider replacing the drive or control board. Contact your local distributor for more assistance.

What to do if LiteOn EVO 6800 show PID Feedback High?
- C
  carlos41Aug 29, 2025
  If your LiteOn DC Drives displays a 'PID Feedback High' error, the possible causes are: * Inappropriate settings in b5-22 and b5-23. * Incorrect PID feedback wiring. * Feedback sensor malfunction. * Feedback input circuit malfunction. To resolve this: 1. Confirm b5-22 and b5-23 settings. 2. Correct the wiring. 3. Replace the sensor if it is damaged. 4. Replace the PCB or drive. Contact the local distributor.

Why does my LiteOn DC Drives show Overvoltage?
- B
  brenda72Nov 21, 2025
  Overvoltage in LiteOn DC Drives can occur due to several reasons: * Surge voltage entering the drive input power. * Short circuit in machinery output. * Ground fault in the output circuit causing the DC bus capacitor to overcharge. * Electrical signal interference causing drive malfunction. * Disconnected PG cable. * Incorrect PG cable wiring. * Electrical signal interference with PG encoder wiring. To resolve this: * Install a DC link choke, especially if using a thyristor convertor and phase advancing capacitor on the same input power supply. * Check the motor power cable, relay terminals, and motor terminal box. * Correct grounding shorts and reapply power. * Address interference by checking control circuit lines, main circuit lines, and grounding wiring.

What to do if LiteOn DC Drives PID Feedback is Low?
- M
  Mathew BenjaminSep 18, 2025
  If your LiteOn DC drive is showing PID Feedback Low, check and correct the settings in b5-12 and b5-13. Also, ensure that the PID feedback wiring is correct. Replace the sensor if it is damaged.

Why LiteOn DC Drives PID Control Selection Fault occurs?
- E
  Erik JonesSep 22, 2025
  If you encounter a PID Control Selection Fault on your LiteOn DC Drive when b5-00 (PID Control Setting) is set to 1 to 4, correct the parameter settings. This includes ensuring that b5-14 (PID Sleep Start Level) is set to 0.0, b1-02 (Stopping Method Selection) is not set to 2 (DC Braking to Stop) or 3 (Coast to Stop with Timer), L2-01 (Frequency Command Lower Limit) is not 0 when b5-00 = 1 or 2, and b5-10 (PID Output Reverse Selection) is not 1 (Reverse Enabled) when b5-00 = 1 or 2, and L2-01 is not 0 when b5-00 = 3 or 4.

What to do if LiteOn DC Drives shows undervoltage?
- R
  rileytammySep 8, 2025
  If your LiteOn DC drive displays an undervoltage error, check the drive input power wiring and tighten the terminals. Ensure the voltage matches the drive input power specifications. If problems persist, cycle the power to see if the issue resolves. If not, consider replacing the entire drive or the control board.

What to do if LiteOn EVO 6800 motor overheat?
- A
  alex95Sep 5, 2025
  If a LiteOn DC drive shows a motor overheat, first, ensure the motor temperature input (terminal MT) wiring is correctly connected. Then, check for any machinery faults. Finally, check the load, acceleration/deceleration time, and cycle time. You can reduce the load, increase C1-00 to C1-07 (Acc./Dec. Time) settings, or adjust d1-02 to d1-11 (V/F Characteristics).
