Weko 5586813 is a high‑power control board used in industrial motor drives and servo systems, typically mounted within the drive enclosure and interfacing with power modules, analog I/O, and communication buses. Common failure modes on this board include shorted or open traces around the MOSFET driver area, burnt capacitors on the DC link filtering section, and degradation of the isolated galvanic isolation transformers due to thermal cycling. Initial checks should verify proper 48 VDC bus voltage and continuity of the power supply rails; inspect for visible burn marks, cracked solder joints, or swollen electrolytics on the board; and review any diagnostic logs or fault codes generated by the drive’s controller software.[oss-gpt-20b]
