Re: Servo heating

Jon,
Your probably right. The servos are big, rated 160 volt, 5" diameter,
10" long, 1K line encoders, no tach and 2.5:1 reduction. There are no
name/data plates. I'm running G320's at 78 volts, 10 amps. Originaly
machine could do 120 ipm, now I get about 60 which is OK for what I do.
Original AMPs were blown. The machine is much bigger than a Bridgeport
series 1.

I will go back and try re-adjusting the gecko. The machine runs fine,
other axis are stone cold. The Y axis just gets pretty warm but its not
too hot to hold on to for a couple of minutes. Much cooler than
McDonald's coffeee :~)
