Re: [CAD_CAM_EDM_DRO] Re: Encoder question

ok, I knew there were s&d to linear -+10 volts and so on, every once in a
while i heare about them, but up until now i had done little with servo's in
the last 20 years.
basically i want to use some pittman motors with 500 encoders for a small 3
axis project. also have another servo project that is more like measuring
and using s&d softwear for control and read-out. small is good. motors run
1.5 amps 3 loaded 21 volts so a nice small s&d servo board would do fine.
thanks, brian f.
