I'd run them at 70V and use a DC Toroidal supply not AC. The motors "Safe" running is 55V but we know from experience they will handle 70V without any trouble so thats where I'd be running them.
Reason I'd run DC is because the capacitors handle back EMF better and deliver smoother power. Don't know these drives or the Supply your using so hard to say how they will handle any Back Emf but it's something you need to consider esp if the Gantrys heavy and you plan to run the machine fast.?
