07 Overload fault: Excessive motor load, motor stalling, improper overload parameter settings. Reduce load, investigate the cause of stalling, and reset the overload current
08 Overheating fault: Cooling fan failure, high ambient temperature, blocked air duct. Replace the fan, improve ventilation, and clean the air duct
13. Grounding fault output terminal short circuit to ground, motor insulation damage. Check the output circuit and test the motor insulation resistance
2. Preventive maintenance
Regular inspection: Check the operation status of the cooling fan and the cleanliness of the air duct every week; Check the tightness of wiring terminals and the insulation layer of cables every month; Quarterly testing of bus voltage and output current balance.
Maintenance records: Use HIM to view parameters such as "Elapsed Run Time" and "Motor OL Count" to predict component lifespan (such as fan lifespan of approximately 20000 hours).
