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
