I don't know if I am doing it right...
I go into motionlink and scan for drives, click exit instead of breaking the link.

I go into BDS5 other settings
Faults and status
Show error history
Err 14 power bus
Err 63 Not at this level
(Those are the only two errors it shows and it shows them multiple times.)

I also had a look in the Drive settings tab and it says the Bus voltage is 230VDC. Isn't the bus voltage 320VDC?
