Why EFIXLAB?
- Full αi chain — Fanuc CNC + PSM + αi-SVS/SVM + αi-SP in one service. We service comprehensively, not just individual modules.
- FSSB diagnostics — verification of the FSSB (Fanuc Serial Servo Bus) bus and communication integrity after repair.
- Older series (A06B, A06B-6) — we repair older models A06B-6078, A06B-6088, A06B-6117 and others. We have spare parts.
- Fanuc alarm codes — we know alarm types 360/361/362 (overcurrent), 400/401 (power circuit failure), 431 (IGBT) and others. Fast diagnostics.
- Test on a test motor — every drive is verified on a Fanuc test motor before return.
- 12-month warranty — on all performed work.

Dziękujemy! We have received your request — our Fanuc specialist will contact you shortly.Frequently asked questions
SV alarm 360 (overcurrent) indicates a damaged IGBT or motor short circuit. Diagnostics will determine whether the problem is in the drive or motor. Alarm 361 is L-phase fault, 362 is overcurrent digital detect.
Yes — we repair old PSM A06B-6093 modules and other older Fanuc power supplies. Replacement of rectifier, capacitors and control cards.
Diagnostics: 1–2 business days. Repair: 5–7 business days after approval and receiving necessary components. Express mode for stopped machines. As a rule — repair time may be significantly extended depending on component availability and repair complexity. Deadlines are agreed individually with the client.
Fanuc Servo Amplifier Repair — Alpha, Beta, and PSM Power Supplies
Fanuc servo amplifiers — Alpha series (A06B-6114, A06B-6117, A06B-6240), Beta series (A06B-6130, A06B-6132), and Power Supply Modules (PSM, A06B-6087, A06B-6110) — are the drive backbone of every Fanuc CNC system and many Fanuc robots. These amplifiers convert DC bus power into precisely controlled motor currents for axis and spindle motion. With the largest CNC market share globally, Fanuc amplifier repair demand is substantial and ongoing.
Common Fanuc amplifier failures include IGBT power transistor degradation in both servo and spindle amplifiers, DC bus capacitor aging in Power Supply Modules, input fuse and rectifier failures from mains transients, current sensor drift causing axis alarms, control circuit processor faults, and connector damage. Alpha i-series (SVM, SPM, PSM) amplifiers are well-designed but still susceptible to power stage failures under heavy machining loads, while older Alpha and Beta series face increasing component aging.
EFIXLAB provides comprehensive Fanuc amplifier repair for all generations. Our service covers SVM (Servo Module) and SPM (Spindle Module) power stage diagnostics and IGBT replacement, PSM power supply module capacitor bank renewal and rectifier repair, control circuit board component-level repair, and current sensor calibration. We test all repaired amplifiers with motor loads, verify proper servo and spindle operation, and check alarm history to ensure clean fault-free operation.
Fanuc amplifier repair saves 40–65% versus Fanuc OEM replacement pricing — significant savings given the premium cost of Fanuc parts. For machine shops running multiple Fanuc-equipped machines, systematic amplifier repair provides meaningful annual maintenance cost reduction. For legacy Fanuc drives no longer available, repair is essential. All Fanuc amplifier repairs include load testing and our 12-month warranty.
