01 / Scope

Our FANUC Servo Drive Repair

Fault diagnosis across the FANUC Servo Drive range — alpha-i servo amplifiers (SVM), beta-i servo amplifiers and alpha-i spindle amplifiers (SPM)

Component-level repair with genuine FANUC and OEM-grade parts

Parameter and program backup taken before any work using FANUC Ladder III

Root-cause diagnosis of SV overcurrent alarm, PSM DC-link / charge fault and pulse-coder (encoder) alarm and related fault codes

Load testing and performance verification before reinstallation

Migration path to current FANUC models where alpha-i servo amplifiers (SVM) is end-of-life

06 / Overview

About FANUC Servo Drive Repair

FANUC drive faults are diagnosed as a system: the Power Supply Module (PSM), Servo Amplifier Module (SVM) and Spindle Module (SPM) share a DC link, so a fault on one can present on another. We read the amplifier LED codes and the CNC alarm together to find the real source — a failed IPM in an SVM, a PSM charge fault, or a pulse-coder feedback problem.

We repair alpha-i and beta-i amplifiers at component level and can recover absolute pulse-coder data, so axis home positions and referencing survive the repair.

Frequently asked questions

Do you repair FANUC servo drive repair or only replace units?+
We repair at component level wherever it is economical — alpha-i servo amplifiers (SVM), beta-i servo amplifiers and alpha-i spindle amplifiers (SPM) and related models. Replacement is recommended only when the unit is genuinely beyond economic repair or spares are unobtainable, and we will tell you which rather than defaulting to a costly swap.
Which FANUC models do you cover for servo drive repair?+
We service alpha-i servo amplifiers (SVM), beta-i servo amplifiers, alpha-i spindle amplifiers (SPM), alpha-iS / beta-iS servo motors and alpha-i Power Supply Modules (PSM), including current and end-of-life generations. Tell us the exact model when you raise a request and we match a technician experienced on that FANUC platform.
Will my FANUC settings survive the repair?+
Yes. We back up parameters and programs with FANUC Ladder III before any hardware work and restore or verify them after repair, so your commissioning, FANUC application settings and referencing are preserved.
How quickly can you provide FANUC servo drive repair?+
We're a verified-technician network serving factories across India from our Hyderabad base. For registered factories we dispatch a technician in under 4 hours across Hyderabad's industrial clusters, and within hours through local technicians in other regions — including emergency FANUC breakdowns, 24/7. Where workshop repair is needed we collect, repair and reinstall with full load testing.
