Mesa 7I77 and Milltronics mill wiring

 Hi, I've been collecting parts for when my old Dos controller for my Milltronics Mill decides to quit. I'm wiring up a new controller box with the 7i77 in it and I'm at a stand still with the analog drive wiring, the 7i77 has 4 outputs per drive and the glentec drives have only 2 inputs and how they are wired confuses me. here is a wiring diagram from the mill, can anyone tell me the correct way to connect the 7i77 to it?  

ena+, ena - is a floating switch, it means that the driver for a specific motor is enabled through it when you enable machine from linuxcnc.. if your driver is always enabled, you don't need to use ena i think..Gnd and Aout is the analog  output signal from 0-10v(please read the manual for 7i77), I'm not sure how it is on your driver to connect correctly, someone from here who understands schematics better ,will add, i hope. greeting

I had a similar question, so maybe something on this post will help

pay attention to the fact that the 7i77 is sensitive to a short circuit and like that, i broke one like that... I advise you to try it on the driver first, maybe with a 1.5v battery to see if the motors start..

Where does 22 and 1-1 go on the other pages?

1-1 is the servo drives and 22 is a multiple contact relay.

To me, this looks like the right side is the driver... and the left side, exactly 1-1 and 22 wires come from that old controller, or am I wrong? do you have a more complete schematic, photo of the driver?

Servo's on left, controller on right.

yes, sorry, that's how it should be.. the encoder goes to the controller.. are there physically on the driver, apart from the input for the tacho 1-3 1-4, some two wires for the analog input somewhere?.. also does that old controller work at all, maybe jogging? there should be a pair of analog input wires on the driver.it seems to me that 1-1 is a common gnd.. and that 22 are + analog output... it just bothers me why it goes through the relay.. if the machine is already working, i would try to measure the voltage between 1-1 and 22

or maybe is 1-1 +analog input on driver..have no idea:(

So 22 is the ground plain, and the drives do not use individual enables as there is a system master enable. What concerns me is that it looks like on e-stop the relay pulls all the analog signals to 0, won't that short out the analog output of the 7i77 ( if it was at a positive voltage move?
