I have a buddy that has a VF1. The machine is wired for the forth axis. We are looking at wiring a seperate servo in the forth axis terminal but do not know the description of each pin in the plug, for say power (voltage), step and direction output, encoder feedback, grounds, things like that Does anyone know this pin description???

This seperate servo will be running a automatic feeder.
Haas says buy a forth axis $7000 and take the servo off and run your feeder with it. LOL

Also I had this question asked to me today and I didn't have a answer for ,is the VF1 a TTL language out put or a step and direction standard?? Anyone know?
I would appreciate any and all information that I can get!!

Thanks,
Dave
