Issue:
What can cause CrF1 (Precharge Fault) on ATV930 when Bonitron unit (or other power supply) is used to power the DC Bus?

Product Line:
ATV930

Environment:
All

Cause:
NA

Resolution:
A parameter needs to be set in ATV930 to tell it that it is not using the internal precharge circuit.
First set the Access Level to Expert in Menu 8: My Preferences.
Then go to Menu 5: Complete Settings > Generic Functions > Bus Ref Link > DC Bus Source Type.
Then select the option for Drive with REC(MCPE).
