Bridgeport VMC1000 refit

my last post might make it look like i've not really been trying... but trust me I've been looking... 

now the original wiring is still in place... and here is a picture...

and in this picture you can see the various ports, and connections.. and i've been trying to understand what i'm looking at, just as much as finding the pinouts for making the connection for a mesa card... 

so maybe if you know the missing info., please feel free to enlighten me.. 

thanks

Those are the drives, for sure, not sure what the big box on the left is, but i would say you are looking at the wrong part.
Follow the encoders, those shoukl go to the controller, usually where the pc and monitor are, that is where the work sbould be done.
Almost always the drives remain untouched, everything connected to drives remains as is.

Off the top of my head, page 110, 263, 380 or thereabouts should have info on analog stuff and encoders.

Looking around a bit with no prior knowledge, 6SN1145 is an "infeed module" (that produces the DC bus for the power modules?). 6SN1123 are the "power modules" (motor drives?). The type of control input is decided by the control card in each power module, in this case 6SN1118-0AA11-0AA1.

Searching for this on Siemens' web page finds a bunch of manuals, but they all seem to cover a newer and only partially compatible control board: link .

It's difficult to see in the pictures, but is there a X321 connector? If so, "56" and "14" is Speed setpoint 1, differential +/-10V input with "14" as the reference point.
