Vigoservo ARN60-A Servo Drive

The ARN60‑A is a Nabtesco Vigoservo servo drive rated for 200–230 V AC, 3‑phase operation up to 50/60 Hz and a maximum current of about 9 A per phase. Common failure points in this class include power supply over‑voltage or ripple, overheating of the driver’s MOSFETs, degraded input filter capacitors, and loss of communication with the host controller due to bad I/O connections or firmware mismatches. Begin by verifying that the AC mains voltage is within spec and that the drive’s internal fuse and protection diodes are intact; then check the status LEDs/diagnostic outputs for fault codes, followed by a visual inspection of the power supply board for burnt components or loose solder joints.[oss-gpt-20b]
