Common failures & inspection points

Cooling fan, filter, or heat-sink fouling causes overtemperature alarms, derating, or protective trips
Input supply, fuse, breaker, rectifier, or DC-link faults cause undervoltage, overvoltage, or failure to start
Output cable, motor, insulation, or power-semiconductor faults cause overcurrent, earth-fault, or drive trips
Control, encoder, feedback, or communication faults result in unstable speed, incorrect command response, or network alarms
Parameter corruption or incorrect settings after service can cause poor acceleration, nuisance trips, or operation inconsistent with the driven machine

Service & Maintenance

Check cabinet cleanliness, cooling airflow, fan condition, terminals, earth connections, input and output alarms, event history, motor current, feedback signals, and communication status. Parameter changes and electrical measurements must follow the manufacturer procedure and vessel electrical safety rules.
