Trio have helped to set up the JXCE1 before. It is not a standard axis as far as the controller is concerned so if you look at the attached EC_EXTEND you will see that all the objects are mapped to VRs and so you must look at the manual and see what the data needs to be set to and also what the data coming back from the drive means.
FOr example these will be VRs:
From VR(200) to VR(214). VR(205) is the Target Position.
You can't control this with WDOG or MOVE.
