ABB VFD REPAIR & REFURBISHMENT

ABB ACS355 repair and refurbishment.

Component-level repair for the ABB ACS355. Bench diagnostics, engineer-led, tested before return.

Overview

ACS355 repair and refurbishment

The ACS355 is a popular industrial drive covering 0.37 kW to 22 kW, widely used in pumps, fans, conveyors, and compressors across UK industry. Its straightforward design and wide installation base mean reliable component sourcing and proven repair procedures.

Expertise

Common ACS355 faults we fix

  • IGBT module failure in the inverter bridge — the most common ACS355 failure, particularly following a supply transient or sustained overload event

  • Brake chopper fault causing DC overvoltage trips (fault F0005) during rapid deceleration in high-inertia applications

  • Control card faults causing parameter loss, I/O failures, or fieldbus communication errors

  • Electrolytic capacitor aging on the DC bus — prevalent in drives after extended service

FAQ

ACS355 repair FAQs

My ACS355 shows fault F0001 (overcurrent) — is the drive repairable?

F0001 is commonly caused by IGBT failure, but can also indicate a motor winding fault. We carry out a bench diagnostic to confirm whether the fault is in the drive before quoting a repair.

Can you replace the DC bus capacitors on an ACS355 as a preventative measure?

Yes. Preventative capacitor replacement is worthwhile on ACS355 drives after extended service, particularly in applications with high switching duty.

Do you repair ACS355 drives used in pump and fan applications?

Yes. Pump and fan drives often run long duty cycles which accelerate fan and capacitor wear. We inspect all wear-prone components as part of the refurbishment.
