Vacon NXS repair and refurbishment
The Vacon NXS is the standard version of Vacon's NX platform, covering 0.75 kW to 2.2 MW across multiple frame sizes. It is widely deployed in pump, fan, conveyor, and general industrial applications across the UK — and now part of the Danfoss Group, it continues to be sold and supported under the Vacon brand.
Common Vacon NXS faults we fix
-
IGBT power unit failure in the inverter stage — the primary NXS failure mode, typically presenting as overcurrent, earth fault, or output phase loss alarms
-
APBU or APFIFF control board failure causing parameter errors, communication loss, or drive inhibit conditions without a power stage fault
-
Cooling fan failure in larger NXS frames causing thermal derating or emergency shutdown in continuous-duty plant room installations
-
Option board (OPTC, OPTE, fieldbus cards) failure affecting network communication or encoder feedback in automated systems

Vacon NXS repair FAQs
Do you service different Vacon NXS frame sizes?
Yes. We service a range of NXS frame sizes — contact us with your specific frame and we will confirm.
My Vacon NXS has a control board fault — can this be repaired without replacing the power unit?
Yes. The NXS modular architecture allows us to address control board faults independently of the power unit in many cases. We carry out a full bench diagnostic to confirm the fault location before quoting.
Does a Vacon NXS repair include functional testing?
Yes. All repaired drives are tested under controlled bench conditions to verify the power stage and control loop before despatch.
