But, I have gotten it down to 2 power wires, 2 MPG wires and for a 3-axis pendant, you need a button ground and 2 wires for rate selection and 3 wires for axis selection. I have an enable button in series with the axis selector, so when that button is not pushed, the MPG does nothing. This prevents accidental movement when I'm not expecting it, and also allows me to preset the jog dial to a major division before pushing the button, so I can have a specific amount of movement by counting numbered marks on the dial. So, that is 10 wires. I also add another two for the estop chain, real handy to have an estop right on the pendant. See http://pico-systems.com/pendant.html I actually have a smaller one on my minimill that is even handier, I don't have a picture of it, yet.
