Panasonic AMKB200820LAK is a 100 V, 200 W AC servo motor designed for high‑precision motion control in industrial automation and semiconductor tooling. Common failure modes on this series include insulation breakdown of the stator windings, bearing wear leading to increased vibration, and loss of encoder or resolver signal due to cable damage or connector corrosion. For initial troubleshooting, verify that the supply voltage is within spec and that the motor’s current rating matches the drive output; check all I/O connections for continuity and proper polarity; inspect the motor housing and bearings for signs of wear or overheating; and review any error codes logged by the servo controller (e.g., over‑current, phase loss, encoder fault).[oss-gpt-20b]
