Teijin-Seiki ARS135-25 Servo Drive

The Teijin Seiki ARS135‑25 is a 2.5 kW AC servo drive designed for industrial motion control, operating on 200–230 V AC at 50/60 Hz. Common failure points in this class include power supply overloads or voltage spikes causing the internal power module to fail, overheating of the motor driver ICs, and degradation of the input/output signal conditioning circuits. For initial troubleshooting, verify that the incoming line voltage is within spec and that the drive’s protection relays are not tripped; check all I/O terminals for correct wiring and continuity; then review any diagnostic LEDs or error codes displayed on the unit’s front panel.[oss-gpt-20b]
