I'm not familiar with the Rutex boards, but I've seen this sort of thing before. Make sure you have the command signal from the Rutex to the servo amp connected properly. That is, make sure the 0v on the Rutex is connected to the 0v on the drive. If you have them reversed you will essentially be grounding the analog signal from the Rutex. If swapping this around causes the axis to run away, you will need to also swap the A and NOT A encoder signals to get it back in phase. THEN, if the axis direction is backwards, this will have to be changed in the control software.
Hope this helps,
