What to do if LiteOn EVO 6800 shows motor overload?
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?
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?
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?
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?
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.
What does it mean if my LiteOn EVO 6800 DC Drives show PID Feedback Low?
If your LiteOn DC Drives shows a 'PID Feedback Low' error, it could be due to: * Inappropriate settings in b5-12 and b5-13. * Incorrect PID feedback wiring. * Feedback sensor malfunction. * Incorrect feedback input circuit. To fix this: 1. Correct b5-12 and b5-13 settings. 2. Correct the wiring. 3. Replace the sensor if it is damaged. 4. Contact the local distributor to replace the board or the drive.
What to do if LiteOn DC Drives PID Feedback is Low?
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?
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?
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?
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).
