Description:
Runtime error using the 'switch on controller' command.
The main relay is open.
A valid nominal DC bus voltage UDC_NOMINAL could not be detected.
The rate of change of the filtered DC bus voltage UDC_FILTER is greater than 62.5 VDC / s.
The rate of change of the filtered DC bus voltage UDC_FILTER is less than -6.25 VDC / s.
The filtered DC bus voltage UDC_FILTER sporadically sinks below the minimum cut-off voltage 0.9*MAX(UDC_NOMINAL, UDC_DETECTION).
The filtered DC bus voltage UDC_FILTER sporadically exceeds the limit voltage:
|--------------------|----------------------------------| | 8Vxxxx.00-x | 746 VDC (1.1*sqrt(2)*480VAC) | | 8Vxxxx.50-x | 357 VDC (1.1*sqrt(2)*230VAC) | | 8BxP | 746 VDC (1.1*sqrt(2)*480VAC) | | 8C | 880 VDC | | 8D | 880 VDC | | 8EIxxxHxxxx.xxxx-x | 825 VDC | | 8EIxxxMxxxx.xxxx-x | 358 VDC | | 80 | 88 VDC | |--------------------|----------------------------------|
Reaction:
See error number 4005.
Cause/Remedy:
See Power unit
-> Request the status 'controller ready' before the command 'switch on controller'.
Mains disturbance: Large DC bus voltage fluctuation. -> Check the filtered DC bus voltage UDC_FILTER.
