Vacon 100 repair and refurbishment.
Component-level repair for the Vacon 100 series. Bench diagnostics, engineer-led, tested before return.
Vacon 100 repair and refurbishment
The Vacon 100 series — including the Vacon 100, Vacon 100 Flow, and Vacon 100 Industrial — is Vacon's current mid-range platform, introduced to replace parts of the NX range in simpler applications. Despite being a newer platform, the same failure modes apply to the power stage and cooling systems.
Common Vacon 100 faults we fix
-
Power module failure in the IGBT inverter stage presenting as overcurrent or earth fault alarms, particularly following supply voltage transients
-
Cooling fan failure causing thermal derating in panel-mounted installations — the Vacon 100 platform uses integrated fan assemblies that wear over time
-
Control card faults affecting integrated fieldbus functions or the drive's built-in PLC capability
-
DC bus capacitor degradation on units that have been in service for several years in high-cycle applications

Vacon 100 repair FAQs
Can you repair a Vacon 100 Flow drive used in a pump application?
Yes. The Vacon 100 Flow is a pump-optimised variant of the Vacon 100. We service it in the same way as the standard Vacon 100, with awareness of the pump application context.
My Vacon 100 trips on thermal fault even in a cool enclosure — what is the cause?
A thermal trip in a cool enclosure is typically caused by a faulty cooling fan or a blocked heatsink rather than genuine overheating. We check both during the bench diagnostic.
Do you offer a no fix no fee repair for Vacon 100 drives?
Yes. Our no fix no fee policy applies to all Vacon repairs — you only pay if we successfully repair the drive.
