Common Failures
Mitsubishi Fault Codes We Diagnose & Fix
FR series and MR-J fault codes traced to root cause at component level — no unnecessary board replacements.
E.OC1 / E.OC2 / E.OC3 — Overcurrent
IGBT failure on FR-A800. E.OC1 at acceleration, E.OC2 at constant speed, E.OC3 at deceleration. Component-level IGBT replacement — not a full power unit swap — cuts repair cost significantly.
E.OV1 / E.OV2 / E.OV3 — Overvoltage
DC bus capacitor degradation or brake circuit fault. Capacitor bank replacement combined with brake chopper inspection resolves recurring OV faults — especially on FR-A/F series over 5 years old.
E.THM — Motor Overload / IGBT Desaturation
Gate driver board fault causing false thermal trips on FR-A800 and FR-D800. Board-level IC repair restores correct IGBT control and eliminates nuisance trips at mid-cycle.
MR-J4 Alarm 16 — Encoder Error
Encoder interface circuit failure on the servo amplifier board — not necessarily the encoder itself. We diagnose the MR-J4 amplifier at component level before any encoder replacement is recommended.
Why Flexa Systems
The Flexa Advantage for Mitsubishi Repair
Deep knowledge of FR series drive hardware, MELSEC PLC boards, and MR-J servo amplifier circuits — repaired at component level.
FR Series at Component Level
We repair FR-A700/A800 and FR-F700/F800 at IC level — individual IGBT replacement, gate driver repair, and DC bus capacitor replacement. No unnecessary board swaps.
2-Year Parts & Labor Warranty
Every Mitsubishi VFD, PLC, and servo amplifier repair is backed by a 2-year warranty. Full functional load test before shipping — all drive parameters preserved and verified.
Fast Turnaround
Most FR series VFD and MR-J servo repairs are completed in 3–5 business days. Rush 24–72-hour service is available for critical production downtime situations.
Significant Savings vs. OEM Replacement
New FR-A800 or FR-F800 drives cost $2,000–$15,000+. Our component-level repair typically runs 30–50% of replacement cost — with a longer warranty than Mitsubishi OEM new parts.

Can you repair Mitsubishi MELSEC PLCs?
Yes. We repair MELSEC FX3U, FX5U, and Q series CPU modules, I/O expansion modules, and communication cards. PLC program is always backed up before service and fully restored — no reprogramming required.
Do you repair Mitsubishi GOT HMI panels?
Yes. GOT1000 and GOT2000 series touchscreen panels — display panel replacement, touch layer repair, and control board service. Screen goes blank or touch becomes unresponsive? These are common GOT failures we handle regularly.
What are the most common Mitsubishi FR drive failures?
Most common Mitsubishi drive fault modes repaired at component level:
- E.OC1 / E.OC2 / E.OC3 — IGBT overcurrent, power module failure
- E.OHT — overtemperature, fan or heatsink fault
- E.UVT — DC bus undervoltage, capacitor degradation
- E.CPU — control board CPU fault
What warranty do you offer on Mitsubishi repairs?
All Mitsubishi repairs carry a 2-year parts and labor warranty. Full load test before return shipment. No fix, no fee.
