I pulled to the old servo drives out of my Matsurra bed mill and got
all the wire run cables separated as much as possible. Most of the I/O
cables have less than ten conductors and you can deduce what they are
for by where the cable run goes.

I have two fifty conductor cables that go to the operator panel. I'm
guessing fifty inputs on the operator panel so there are a great many
more wires than used. I have no manual for this machine and these
wires aren't numbered. Looks like a REAL MESS to figure out the
function of each wire.

Each input is pretty simple, if it is made it conducts voltage. But
doing this many at once becomes a snow storm. Any suggestions on best
approach?

That's a very tough job. I would first invest a lot of effort into
finding a manual and schematic.
