Westamp 30059 is a servo drive controller board used in industrial motion‑control systems to amplify and regulate motor current. Common failure points on this class of boards include burnt or degraded MOSFETs/IGBTs, damaged gate drivers, shorted bridge rectifiers, and capacitor electrolyte leakage; overheating from inadequate cooling or power supply spikes often precipitates these faults. Begin diagnostics by verifying the input voltage rail with a multimeter, inspecting for visible burn marks or swollen electrolytics on the board, and checking I/O continuity to the motor driver outputs; if available, review any diagnostic logs or error codes generated by the host controller.[oss-gpt-20b]
