Re: [CAD_CAM_EDM_DRO] Clifton Precision Servo Specs

Sounds like some motors I have at home. Did you buy them from Gateway
Electronics, years ago? I've also found them in old line printers, for
moving the print head back and forth. The outputs are Open Collector,
meaning they need a pullup resistor to +5V for TTL output. There are two
sets of lines on the glass disk on the shaft encoder. Different
resolutions. Each one has A and B outputs, 90 deg. apart. I was just
planning on useing one for Halloween, to keep track of a rotating mirror
position, while I strobe a laser pointer. Should look cool in the fog from
the fog machine.

What other info do you need? What is your application? What do you want
to drive them with?
