Fanuc LTD. A06B-6077-H111 A drive

A06B‑6077‑H111 is a Fanuc Alpha series power supply module (PSM‑11) rated at 49 A, 13.2 kW, designed to feed the A06B servo amplifiers in CNC machines. Common failure modes include overheating of the internal fan or heatsink, degradation of the output capacitors leading to voltage ripple, and failure of the power MOSFET array due to over‑current events. First‑check diagnostics: verify input 200–325 VAC supply levels and polarity; inspect the module for visible signs of burn marks, swollen electrolytics, or fan obstruction; and review any error codes from the host controller that reference “PSM” or “power supply fault.”[oss-gpt-20b] Post Comment
