Code designation cause remarks
E33-01 Unsymmetrical bus voltage The di󰀨erence between the bus voltages
of the power modules 1 and 2 is >60V.
- check power modules
- check the at ribbon cable between
MAPRO and DRV
- check connector X17 on DRV
for details see page 48
E33-02 Unsymmetrical bus voltage Startup The di󰀨erence between the bus voltages
of the power modules 1 and 2 is >60V at
startup.
E34-00 Fan current The current consumption of the fans is
too high.
- check fans and their wiring
for details see page 58
E41-01 Mains loss The primary DSP couldn’t detect a mains
supply.
- check mains supply
- check wiring between NEFI and DRV
