Thank you Al, I appreciate the information a great deal!

TC429, I'm going to look into the suggestions you've made and try to learn more from that. I have everything working now, but I'm always interested in learning more.

With a little searching for deceleration and reference point return stuff I came up with G076.5 so I did a search in the ladder for that address.

When it came up, I found X003.5 which worked out to be wire 222 at the terminal block.

I wired up a length of cable and put on a pushbutton. Then I switched the machine into the homing mode and held the + jog button. When I pulse my makeshift pushbutton the servo stops and the axis is homed.

This project is a 100% success and I'm very happy about it. Looks like I'm in the market for an older, used rotary table. I guess I'll have to research Fanuc servo compatibility.
