The Teijin‑Seiki AR60‑BAU is a compact servo drive designed for industrial motor control with high‑speed processing and closed‑loop position/speed regulation, typically interfaced via standard fieldbus or analog I/O.

Common failure points in this class of drives include power supply degradation (brownouts, ripple), over‑current protection trips, firmware corruption, and communication link loss. Inspect the 24 V/48 V input rails for correct voltage and low ESR capacitors; verify that the drive’s status LEDs or diagnostic outputs indicate normal operation. Check all I/O connections for continuity and proper termination, then review any error codes displayed on the panel or logged in the host controller before proceeding to component‑level testing.[oss-gpt-20b]
