Has your A06B-6058-H252 Servo unit begun to malfunction? Noticing erratic operation or blown fuses? You likely need your component repaired before it causes greater damage.

The Servo drive in your CNC machine regulates the voltage between the control board and motor. The drive takes the command signal sent from the control panel and amplifies it to a level able to control the servo motor. FANUC AC Servo drives have been known to blow main fuses, have OC and IOC alarm issues and even start smoking when they aren't functioning properly.

The FANUC parts repair experts at Tri Star CNC have over 90 years of collective experience performing component level repairs on Servo drives, power supplies, I/O controllers and spindle amplifiers. We know what it takes to get your CNC machines up and running as quickly as possible when they're down and production is stalled. CNC machine repair professionals at Tri Star CNC Services diagnose the malfunctioning part and take it back to our testing facility for testing on a closed loop. Once we've determined the best course of action, we do one of the following:

  • Repair your part and replace
  • Credit you fairly for the broken part and send a part from our exchange stock
  • Order a new OEM part or engineer our own—whatever costs less

When you need CNC repairs you can trust, choose Tri Star CNC. We offer a 1 year warranty on repairs to ensure you receive defect-free service. If something goes wrong within a year, we will do a complete assembly and repair of your non-working parts at no charge.
