Common Faults and Solutions
Overcurrent Faults:
Possible Causes: Motor overload, motor or cable short circuit, inverter hardware failure, etc.
Solution: Check the motor load, measure the insulation resistance of the motor windings, check the motor cables for damage or short circuits, and replace any damaged components.
Overvoltage Fault:
Possible Causes: Overhigh power supply voltage, untimely dissipation of regenerative energy during motor deceleration, or a fault in the inverter’s internal voltage detection circuit.
Solution: Check the input power supply voltage, adjust the deceleration time setting, check whether the brake resistor and brake unit are functioning properly, and replace any damaged components.
Overheat Fault:
Possible Causes: Cooling fan failure, excessive dust accumulation on the radiator, excessively high ambient temperature, or prolonged high-load operation.
Solution: Replace the faulty cooling fan, clean dust from the radiator surface, improve workshop ventilation, and lower the ambient temperature.
Undervoltage Fault:
Possible Causes: Power phase loss, blown fuse, internal rectifier bridge fault, or aging of the DC bus capacitor.
Solution: Check the power supply line connections, replace the fuse or rectifier bridge module, and check whether the DC bus capacitor is aging or damaged.
Communication Failure:
Possible Causes: Poor communication line connection, incorrect communication protocol settings, or communication module hardware failure.
Solution: Check the communication line connection, confirm the correct communication protocol settings, and replace any damaged communication modules.
