What would cause the ATV930 process drive to get a precharge capacitor fault?

Issue:
What would cause the ATV930 process drive to get a precharge capacitor fault?

Product Line:
ATV930 process drives

Environment:
All

Cause:
DC bus tie with another drive

Resolution:
In a configuration where the drive is connected and supplied by another drive via the DC bus, set DCBS parameter (Generic Functions/DC-Bus Ref Link) to "Drive with REC" as shown in the attachment. This will avoid "Precharge Capacitor" faults due to power supplied direct to the DC bus.

Note that the ATV600 series is not designed for applications where the DC bus is powered from an external DC source.
