Common Faults and Solutions 1. Overcurrent Fault Symptom: The driver displays an overcurrent alarm, and the motor may not start normally or stop suddenly during operation. Possible Causes: Short circuit of the motor cable; Short circuit inside the motor; Damage to the power module of the driver; Excessive load or jamming, resulting in an excessively large motor current. Solutions: Check whether the motor cable is damaged or short-circuited. If so, repair or replace the cable; Use an insulation resistance tester to check the insulation of the motor to determine whether the motor is short-circuited. If it is short-circuited, repair or replace the motor; Check the power module of the driver. If it is damaged, have it replaced by a professional; Check whether the load is jammed or overloaded, eliminate the load fault, and ensure that the motor can run normally. 2. Overvoltage Fault Symptom: The driver displays an overvoltage alarm, usually due to an excessively high power supply voltage or an excessive amount of energy generated during the motor's regenerative braking, resulting in an excessively high DC bus voltage. Possible Causes: The input power supply voltage is too high and exceeds the allowable range of the driver; The braking resistor is not connected or has an incorrect resistance value, resulting in the regenerative energy not being consumed in a timely manner; The braking unit is faulty. Solutions: Use a voltmeter to measure the input power supply voltage to confirm whether it is within the rated voltage range of the driver. If the voltage is too high, adjust the power supply or use a suitable voltage reduction device; Check whether the connection of the braking resistor is firm and whether the resistance value meets the requirements of the driver. If not, replace it with a suitable braking resistor; Check whether the braking unit is working properly. If it is faulty, repair or replace it. 3. Undervoltage Fault Symptom: The driver displays an undervoltage alarm, and the motor may not start normally or run unstably. Possible Causes: The input power supply voltage is too low; Poor contact or disconnection of the power supply line; Fault of the internal power module of the driver. Solutions: Measure the input power supply voltage to confirm whether it is within the allowable range of the driver. If the voltage is too low, check the power supply system, such as the transformer, lines, etc., to ensure the normal power supply voltage; Check whether the connection of the power supply line is firm, and whether there are any loose or disconnected phenomena. Repair or replace the faulty line; If the internal power module of the driver is faulty, have it repaired or replaced by a professional.

4. Encoder Fault Symptom: The driver displays an encoder alarm, and the motor may have a position deviation, be unable to be precisely controlled, or run abnormally. Possible Causes: Poor connection or damage to the encoder cable; Fault of the encoder itself; Loose installation or incorrect position of the encoder. Solutions: Check whether the connection of the encoder cable is firm, and whether there are any damaged or disconnected phenomena. Repair or replace the cable; Use professional testing equipment to check whether the encoder is working properly. If the encoder is damaged, replace it; Check whether the installation of the encoder is firm and whether the position is correct. If it is loose or the position is deviated, reinstall and adjust the encoder. 5. Overheating Fault Symptom: The driver displays an overheating alarm, possibly due to an excessively high internal temperature of the driver. Possible Causes: Poor ventilation of the driver, such as a damaged cooling fan or blocked ventilation openings; Excessively high ambient temperature; The driver operates under high load for a long time. Solutions: Check whether the cooling fan of the driver is operating normally. If the fan is damaged, replace it in a timely manner; Clean the ventilation openings of the driver to ensure good ventilation; Check whether the ambient temperature is too high. If it exceeds the allowable operating temperature range of the driver, take cooling measures, such as installing an air conditioner or strengthening ventilation; Reasonably adjust the working load of the driver to avoid long-term high-load operation. 6. Communication Fault Symptom: The driver cannot communicate normally with the host computer (such as PLC, motion controller), and may display a communication error alarm. Possible Causes: Poor connection or damage to the communication cable; Incorrect communication parameter settings; Fault of the communication interface of the driver or the host computer. Solutions: Check whether the connection of the communication cable is firm, and whether there are any damaged or disconnected phenomena. Repair or replace the cable; Confirm whether the communication parameter settings of the driver and the host computer are consistent, such as baud rate, data format, communication protocol, etc. If there are errors, adjust them; Check whether the communication interfaces of the driver and the host computer are working properly. You can try to replace the communication interface or use other devices for testing.
