| Repair Turnaround Time | Typical reference: 3–6 working days |
The Challenge
The driven motor could not run reliably, stopping a critical machine function and increasing production downtime.
Diagnosis
- The input stage, DC bus, pre-charge circuit, IGBT power section, gate drivers, current sensing, cooling system, and control board were inspected.
Our Solution
- Defective power or control components were replaced as required, cooling and connection issues were corrected, boards were cleaned, and the drive was functionally tested with a motor.
Testing Performed
- Input inspection; DC-bus test; power-stage test; motor rotation test; current monitoring; fault-reset test; thermal and burn-in test.
Final Result
The reference repair process restores normal functional operation after the unit passes the defined electrical, communication, motion, or load checks applicable to the equipment.
Common Fault Codes & Causes
- 2310 – Overcurrent: Motor overload, short circuit, rapid acceleration or power-stage/current-sensing issue.
- 3210 – DC-link overvoltage: High supply voltage, regeneration or insufficient deceleration/braking.
- 3220 – DC-link undervoltage: Low input voltage, phase loss, fuse or mains interruption.
- 2381 – IGBT overload: High output current, overload duty or thermal stress in power stage.
- 4110 – Control board temperature: High internal temperature, cooling/ventilation issue or contamination.
- 4210 – IGBT overtemperature: Cooling failure, overload, fan issue or high ambient temperature.
- 4290 – Cooling: Fan/airflow/cooling path problem.
- 4310 – Excess temperature: Excessive internal temperature or cooling imbalance.
- 4981 – External temperature 1: Motor/external sensor temperature limit exceeded or sensor circuit issue.
- 4982 – External temperature 2: Motor/external sensor temperature limit exceeded or sensor circuit issue.
Preventive Maintenance
- Maintain clean cooling paths, verify motor load and cabling, inspect fans, protect against voltage disturbances, and keep the cabinet temperature within limits.
