The Challenge
Loss of the servo axis stopped accurate machine movement and prevented normal production cycles.
Diagnosis
- The DC bus, IGBT stage, driver board, current feedback, encoder interface, control power, communication circuitry, and cooling system were evaluated.
Our Solution
- Failed electronic components were replaced where required, PCB defects and solder joints were restored, cooling was serviced, and the drive was tested with compatible feedback or motor simulation.
1. BEFORE
2. DISASSEMBLY
3. INSPECTION
4. FUNCTIONAL TESTING
Testing Performed
- Power-up test; DC-bus test; power-stage test; encoder/feedback test; communication test; axis enable test; thermal burn-in.
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
- Overload; encoder wiring fault; power surge; IGBT failure; cooling issue; contaminated board; component aging.
Preventive Maintenance
- Inspect motor and feedback cables, maintain cabinet cooling, prevent overloads, check grounding, and investigate repeated fault codes before continued operation.
