Common Failures
Fanuc Alarms We Diagnose & Fix
Component-level diagnosis on Fanuc servo amplifiers and CNC boards — fault codes traced to root cause, not swapped out.
Servo Alarm 9 — Abnormal Current in Servo Axis
IGBT failure in αi SVM amplifier. Most common alarm in high-cycle machining centers. We replace individual IGBTs — not the full servo module — significantly reducing repair cost.
Servo Alarm SV-025 — Motor Power Cable Disconnected
PSM (Power Supply Module) failure or pre-charge circuit fault. Capacitor and IGBT repair in the PSM. Drive must be fully isolated before diagnosis — we follow full discharge procedures.
Spindle Alarm SP0001 — Spindle Overcurrent
SPM IGBT failure or gate driver fault. Most common on high-cycle spindle applications. Component-level repair on the SPM restores full spindle performance and cycle rates.
CNC CPU / I/O Board Failure
0i/16i/18i control board stops: blank screen, boot loop, or E-Stop active. IC-level board repair. We back up all CNC parameters and PMC ladder before any work begins — no data loss.
Why Flexa Systems
The Flexa Advantage for Fanuc Repair
Component-level expertise, full data backup, and a 2-year warranty — on every Fanuc servo and CNC repair.
Fanuc Servo at Component Level
We repair αi and βi servo amplifiers at IC and module level — IGBTs, gate drivers, PSM capacitors. Not just module swaps. Root cause is diagnosed and documented before repair begins.
CNC Program & Parameter Backup
Before any CNC board repair, we back up all programs, tool offsets, work coordinates, and PMC parameters. Everything is restored after repair. No data loss — guaranteed.
2-Year Warranty on Every Repair
Every Fanuc servo amplifier and CNC board repair is covered by a 2-year parts and labor warranty. Full functional test under load before return to the customer.
Saves vs. New Fanuc Parts
New Fanuc αi SVM modules cost $3,000–$12,000+. Our component-level repair typically runs 30–50% of that cost — and comes with a longer warranty than Fanuc OEM replacement parts.

Can you repair Fanuc CNC systems?
Yes. We repair Fanuc CNC main boards, axis control boards, servo control boards, and I/O modules for Series 0/16/18/21/30/31/32i CNC systems. Parameters and custom macros are backed up before service and restored on return.
What are the most common Fanuc servo failure modes?
Most common Fanuc faults repaired at component level:
- AL-09 (Axis servo alarm) — IGBT module or gate driver failure
- AL-24 (Serial encoder error) — encoder interface board fault
- SP-9001/9002 (Spindle alarm) — spindle drive power stage failure
- DC bus undervoltage — capacitor degradation in PSM
