The bigger Delta AC Servo motors use other connectors than the smaller 400-750Watt models. The connector is also integrated in the motor. Its a military style connector. What we offer here is a set for power (UVW) and encoder cables. These are assembled and tested on our testbench. Cabling is a delicate issue with AC servo systems. We prefer to sell the tested cables, since often errors occur when clients make their own cables. It is however possible to buy the separate connectors and make your own cables.
