CNC machine electrical repair: what we cover
Our CNC machine electrical repair work covers CNC controller repair, CNC drive repair (servo drive repair and VFD repair), CNC PCB repair, power supplies and control cabinet wiring. Fanuc controller repair is among the controller brands we handle, alongside the DSP and PC-based controllers used on routers. As a CNC machine repair service in India, we diagnose with the machine's alarm codes, so note them before sending a board. CNC electronics repair is quoted after testing.

Signs your control panel needs repair
- An alarm code that comes back after every reset
- Servo drive or VFD tripping on overcurrent or overvoltage
- An axis drifting, losing position or not enabling
- Controller or HMI not booting, or a blank screen
- MCB trips, contactor chatter or a burnt smell in the cabinet
- Faults that only appear once the machine is warm
Seeing one of these? Stop and inspect early: a small repair now avoids damage to the shaft, housing or machine.

CNC Control Panel Repair: frequently asked questions
How do I troubleshoot a CNC controller error?
Note the exact alarm code and message, then check the basics: supply voltage, emergency-stop chain, limit switches, cable connectors and fuses. Look up the code in the controller manual; many alarms point to a specific axis, drive or sensor. Power-cycle once only, and if the alarm returns, stop and call a technician rather than forcing the machine.
