Why EFIXLAB?
- ACS800 (EOL) — we repair when others refuse — discontinued ACS800 is still widely used. We have components and experience with this platform.
- DriveComposer / DWL backup — parameterization backup before repair and restoration after, without losing configured values.
- DTC (Direct Torque Control) — we understand the specifics of the ABB DTC algorithm, which is crucial when repairing ACS880/ACS800 control cards.
- Load test — every inverter after repair is tested under load, not just at no-load.
- Priority for stopped production — we react quickly to urgent requests.
- 12-month warranty — on all performed work.

Yes — ACS800 is a discontinued platform but still widely used. We repair RDCU, RINT, AINF cards and IGBT power sections.
Yes — if the control card is operational, backup is possible via DriveComposer Pro or Drive Windows. Parameters are restored after repair.
Most common: F7001 (DC link undervoltage — capacitors or rectifier), F7002 (DC overvoltage — IGBT), F2310 (overcurrent — IGBT), alarms 25xx (control card). Every case is diagnosed individually.
Diagnostics: 1–2 business days. Repair: 5–7 business days after approval and receiving necessary components. Express mode for stopped production. As a rule — repair time may be significantly extended depending on component availability and repair complexity. Deadlines are agreed individually with the client.
ABB Inverter Repair — ACS, ACH, and ACS800 Series Diagnostics
ABB frequency converters — including the ACS310, ACS355, ACS550, ACS580, ACS800, ACS880, and ACH550 series — are among the most widely installed industrial drives globally. From HVAC systems to heavy process industry applications, ABB drives control motors ranging from fractional horsepower to megawatt scale. The diverse application base means ABB drives face equally diverse failure modes depending on their operating environment and load profile.
Common ABB drive failures include IGBT module damage in the inverter bridge (particularly in ACS800 and ACS880 high-power units), electrolytic capacitor aging in the DC link causing ripple current faults, input rectifier failures from mains transients, cooling fan bearing wear leading to thermal trips, and control board issues. The ACS550 and ACS580 series sometimes experience SMPS (switch-mode power supply) failures that prevent the drive from powering up. Legacy ACS600 and ACS800 units are susceptible to fiber optic gate driver communication problems.
EFIXLAB repairs all ABB drive families from the legacy ACS600 through current ACS880 platforms. Our repair process includes complete power stage diagnostics with calibrated motor loads, DC link capacitor ESR and capacitance measurement, gate driver signal analysis using high-speed oscilloscopes, and control board functional testing. We rebuild power stages with genuine or equivalent-specification IGBT modules and replace capacitor banks with high-reliability long-life components.
ABB drive repair is particularly economical for the ACS800 and ACS880 series where power module replacement alone can cost thousands of euros from ABB. Our all-inclusive repair pricing typically saves 40–65% versus new drive cost. For legacy ACS600 and ACS400 series where ABB no longer provides full support, our repair service is essential for keeping these drives operational. All ABB drive repairs include full load testing and our 12-month warranty.
