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 necessa-
ry
- Check the wiring of the regenerative module (power grid
side and DC link)
- Replace the UEC if necessary
Error message
10028 CC%2: UEC dc-link voltage too low (U-min: %4, U-act:
%5)
Cause of error
- DC-link voltage of the UEC is too low
Error correction
- Check the wiring of the UEC
- Check the 3-phase voltage supply of the UEC
- Check the line fuses
- Monitor for sporadic power failures
Error message
10029 CC%2: UEC dc-link voltage too high with RM (U-max:
%4, U-act: %5)
Cause of error
The DC-link voltage is too high despite the use of an RM
regenerative module.
Error correction
- For operation with an optional RM regenerative module:
- Check the regenerative module and exchange it if necessa-
ry
- Check the wiring of the regenerative module (power grid
side and DC link)
- Check the line fuse
- For operation without an RM regenerative module:
- Deactivate the machine parameter uecRecoveryModule
