KEB COMBIVERT S6 repair and refurbishment.
Component-level repair for the KEB COMBIVERT S6 servo drive. Bench diagnostics, engineer-led, encoder function verified before return.
COMBIVERT S6 repair and refurbishment
The KEB COMBIVERT S6 is a servo inverter supporting closed-loop vector and synchronous motor control with encoder feedback. It is used in precision positioning and motion control applications on German-built machinery, where a drive failure can stop a production cell entirely.
Common COMBIVERT S6 faults we fix
-
Control board failure affecting encoder feedback processing, causing closed-loop instability, loss of position reference, or drive inhibit
-
IGBT power stage failure in applications with high dynamic loading — rapid acceleration and deceleration cycles impose greater stress on the inverter stage than steady-speed operation
-
EEPROM or parameter memory failure causing loss of servo tuning data and motor configuration parameters
-
Resolver or encoder interface faults causing incorrect speed or position feedback, typically presenting as erratic motion or following error alarms

COMBIVERT S6 repair FAQs
Can you repair a COMBIVERT S6 that has lost its servo tuning parameters?
We assess whether the EEPROM has failed permanently or suffered a transient corruption. If recovery is not possible, we advise on re-parameterisation using the original commissioning data.
My COMBIVERT S6 shows a following error on a motion profile — is this the drive?
Following errors can be caused by a drive fault, encoder feedback board failure, or a mechanical issue. We carry out a bench diagnostic to confirm whether the fault lies in the drive before quoting a repair.
Do you verify servo function after repairing a COMBIVERT S6?
Yes. We test encoder feedback response and basic drive operation as part of the post-repair bench check. Full servo tuning validation in the installed machine is the responsibility of the machine owner or appointed engineer.
