Drive mfrs recommendations for MOTOR cables ?

Hello Dan, Dean, Mariss, Hans, Tim,?,?,

I'm wondering what our list member step drive mfrs recommend using
for cabling FROM their drives TO the motors?

Shielded?
Individually? Overall? Braided? Foil?

Twisted pairs?

RE: Gauge... Any modifications to the "standard" amps ratings as
supplied by the wire mfrs when the wire is used for PWM drives?

Effect of wire that is "too big", if there is any?

Now how about a few specific apps (I've tried to pick some "typical"
values here):

12VDC PS, 2A drive, 1A motor rating, 3 foot cable length?
Same with a 12 foot cable?

36VDC PS, 2A drive, 2A motor rating, 10 foot cable length?
Same with 5 foot cable? 20 foot cable? 4A motor?

60VDC PS, 5A drive, 4A motor rating, 18 foot cable length
Same with 5 foot cable? 6A motor?

Does drive type (unipolar, bipolar, bilevel) affect these answers?

Any other thoughts or considerations? (besides the need for oil proof
outer covering if used in a machining environment)

Thank you in advance,

Ballendo

P.S. Any special consids for servos, versus steppers? (Just the
motor. We'll assume everyone knows to keep the encoder signals away
from the drive current) Can I just use SJO to the servos?
