Fanuc LTD. A06B-6055-H208 Servo Drive

The A06B‑6055‑H208 is a Fanuc AC spindle drive (digital FINOUT) rated for 8 kW spindle motors and typically used on large CNC machines. Common failure points in this class of drives include degraded power supply capacitors, overheating of the amplifier board, faulty digital communication modules, and worn motor windings or brushes. Initial checks should verify proper input voltage and ground integrity, inspect the drive’s internal cooling fans and thermal paste for obstructions or degradation, and review any logged error codes or fault flags from the CNC controller to isolate electrical versus mechanical causes.[oss-gpt-20b] Post Comment
