7218: DC bus: Nominal voltage detection: Voltage too low

Info: Minimum required DC bus voltage
Data type: REAL

Runtime error using the 'switch on controller' command.
The main relay is open.
The filtered DC bus voltage UDC_FILTER is smaller than the tolerated by 10% lower limit voltage for the automatic nominal voltage detection 0.9*UDC_DETECTION.
A valid nominal DC bus voltage UDC_NOMINAL could not be detected.

See error number 7210.

See Power transmission

Invalid mains: Supply voltage or DC bus voltage is too low. -> Check the DC bus voltage.
Incorrect configuration of the nominal voltage detection: UDC_DETECTION too high.
