The Vigoservo ARS15 is an AC servo drive designed for industrial motion control, typically rated around 0.6 kW with a 200‑230 V input. Common failure modes in this class include power supply over‑voltage or ripple, overheating of the motor winding or driver coils, and degradation of the internal capacitors or MOSFETs due to thermal cycling. Initial checks should verify that the line voltage is within spec and stable, inspect for any visible signs of component burn or corrosion on the PCB, and review the drive’s diagnostic LEDs or error codes (e.g., E‑14) for clues about overcurrent or temperature limits. If the unit still fails after these steps, proceed to test the input/output signals and perform a short‑circuit check on the motor terminals.[oss-gpt-20b]
