What is a PRA fault on ATV61/71 drives?

FA170744

18/06/2014

PRA is power removal fault.  This means that the drive does not detect +24VDC on +24V terminal.  Need to make sure that there is a jumper between PWR and +24V.  SW1 and SW2 switch needs to be on source.  Check power and control supply.  Power could be draining for external reasons.
