Mariss, can we continue?

Ok, upon close inspection, it appears that the factor wiring on the
motors is series.

7 jump 8
5 jump 6
1-2-3-4 individually go to the original drive enclosure.

But, (and this was a cause of initial confusion)...

7 and 5 also are tapped and go to the original drive enclosure for
a total of 6 wires. Initially I was thinking this was a 6 wire drive
and there are some implications to that which I don't fully
understand. Basically, I counted wires in the loom and based my
reseach on that.

So... do I just ignore these 2 additional wires (remember, this is a
pre-made machine and even pulling them out of the loom is a PITA).
According to your last instructions, I guess I just ignore them (ie
cap them off) but I want to make double sure.

In addition,

You specify to set the voltage from the transformer at less than 80v.
Since my transformer outputs 60-70-80vac at the transformer itself
(actually 65-75-85vac via VOM), then this shouldn't be a problem
since I suppose the the downline elements will drop the voltage.
That will more than likely leave me with 2 or 3 options depending on
if the highest tap reads less than 80vdc at the drive.
Lets just pretend that I end up with 55-65-75vdc as my options at
the drives. Do I pick the highest one or the lowest one? What
indicators will I have if I started in the middle as to whether I
should step up a tap, or step down a tap (assuming all are 75vdc or
less)?
The next issue is the current set. You put it at 4 amps. What
indications will I have which would lead me to up that to 5, or 7
amps, or lower it.....as opposed to say changing the voltage on the
transformer or deciding to rewire for parallel at the motor?

To put it another way....
Lets say I just got the machine's table moving. It feels to me that
the motors are too slow and lag under load. Do I change the
transformer voltage, current set amperage, or wiring of the motor,
or which combination in this case?

Next, similar scenerio...
Speed is good, but motor lags under load... which change combination

Next again...
Speed is slow, but enough power or torque to break a
cutter....again...same question (except now is this a X10 issue with
the multiplier, or controller setup?).

There seems to be quite a few options for the novice who is unable
to do this by "feel"

Maybe down the line some expert could write a tuning flow app chart
or something?

Within a month or so, I'll know a lot of these answers, but now
might be a good opportunity to address these with the "ignorant" as
the model end user.

Thanks Again
Sean (who hates being ignorant)
