Error message

10027 CC%2: UEC dc-link voltage too high (U-min: %4, U-act: %5)

Cause of error

- DC-link voltage of the UEC is too high

Error correction

- Check the braking resistor of the UEC and exchange it if necessary
- Check the wiring of the braking resistor
- Check the line fuses
- For operation with an optional RM regenerative module:
- Check the regenerative module and exchange it if necessary
