ABB VFD REPAIR & REFURBISHMENT

ABB ACS580 repair and refurbishment.

Component-level repair for the ABB ACS580. Bench diagnostics, engineer-led, tested under controlled conditions before return.

Overview

ACS580 repair and refurbishment

The ACS580 is ABB's current general-purpose drive, replacing the ACS550 in many OEM and retrofit applications. Despite being a newer platform, it shares many of the same power stage failure modes — and component-level repair is considerably more economical than outright replacement.

Expertise

Common ACS580 faults we fix

  • Power module failure in the IGBT inverter stage — presenting as overcurrent, output phase loss, or earth fault alarms

  • Cooling fan failure causing thermal shutdown, particularly in high-ambient or poorly ventilated panel installations

  • Brake chopper circuit faults causing DC overvoltage alarms during rapid deceleration cycles

  • Control unit faults affecting the drive's integrated safety and fieldbus functions

FAQ

ACS580 repair FAQs

My ACS580 is relatively new but has developed a fault — can you repair it?

Yes. Even relatively new drives can suffer component failures from voltage transients or installation issues. We carry out a bench diagnostic to identify the issue and advise on repair options.

Can you repair ACS580 drives with integrated brake choppers?

Yes. Brake chopper failure is a known fault mode on the ACS580, especially in applications with frequent regenerative braking. We diagnose and replace the chopper circuit where required.

Does the ACS580 repair include a full functional test?

Yes. All repaired drives are tested under controlled bench conditions to verify the power stage, control loop, and safety functions before despatch.
