KEB COMBIVERT drive repair and refurbishment.
Component-level repair and refurbishment for KEB COMBIVERT drives. Engineer-led bench diagnostics, no fix no fee, 2-year warranty.
KEB Automation drives
KEB Automation is a German manufacturer producing the COMBIVERT range of frequency inverters for general purpose, servo, and specialist applications. KEB drives are commonly found in German-built machinery imported into UK manufacturing, and when they fail — often without a local support infrastructure — a component-level repair is typically the fastest path back to production.
Common faults we fix on KEB drives
-
Power stage IGBT failure — the primary failure mode across the COMBIVERT range, commonly triggered by supply transients or sustained overload on the driven machine
-
Control board faults including EEPROM failure, parameter corruption, and loss of encoder feedback function on servo-configured drives
-
Rectifier bridge faults causing undervoltage or unbalanced DC bus conditions, presenting as F-series fault codes at startup
-
Cooling fan and thermal management failure in larger frame sizes, causing thermal derating in warm or poorly ventilated panel enclosures

KEB drive repair FAQs
Do you repair KEB COMBIVERT drives imported on German-built machinery?
Yes. KEB drives are commonly found on imported German machinery. We carry out component-level repairs regardless of the machine's country of origin.
Can you repair a COMBIVERT F5 that shows a fault code on startup?
Yes. F-series fault codes on startup typically indicate a power stage or rectifier fault. We carry out a bench diagnostic to identify the root cause before quoting a repair.
Do you repair KEB COMBIVERT S6 servo drives?
Yes. The COMBIVERT S6 is a servo drive with encoder feedback capability. Servo drive repairs require careful handling of the feedback circuits — we factor this into the diagnostic and repair process.
Are KEB drive components available for older COMBIVERT models?
Compatible components for the COMBIVERT F5 and S6 are generally available. We check parts availability before confirming the repair scope and will advise clearly if a fault cannot be addressed.
