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?

50 conductor sounds like telephone cable. Are the wires stranded or
solid? Are they pairs of wires twisted together? If twisted together,
then you have pairs already and only have 25 pairs to deal with.


There is also 50 conductor (and larger) control cable. Telephone
wire is typically solid 24 or 26 AWG that doesn't hold up well with
vibration.
