i spent a few minutes reading thier page and it looks like a closed system to me, in other words you would have to disconnect the controller and take mach directly to the drives, there is a fellow named cnchelper here on the forum who may know more about this, other wise it liiks like a decent industrial controller, call the manufacturer and get the manual if you do not have one.
also you stated your machine is servo,
