This fourm is about our company products (cncdrive.com) and this controller is not ours, it is a Chinese one.
Due to the fact that the motion controller has +5V as common I think it is likely to have NPN transistor outputs.
Then you could connect the +5V to the Puls+ and Dir+ input of the drive and connect one axis step/dir signals to them, e.g. the CD- and CP-.
Ofcourse I'm assuming that your motion controller supports free configuration of signals to pins (our motion controllers work like that).
However if the pins are fixed to the functions in your motion controller then it will not work with your step/dir servo spindle, then you will have to get a different motion controller, e.g. our AXBB-E motion controller + breakout board can work like that:
