To re-use the servo gear, I'd like to know what signals get sent
down that ribbon. Can anyone suggest a way of finding out (that
doesn't involve hours with a meter and CRO)?
Clifford.
Hi Clifford.
You might be able to find a manual for the thing online somewhere, especially
if the drive is a rebadged Fujitsu, Cypher, or other common brand. I have
manuals for several 9-track drives, and they all have schematics.
I am using Fujitsu 9-track reel motors for the main drive on my robot. The
servo board was about 8x14", and contained two bipolar H-bridges built onto a
massive heatsink. I scrapped that thing, and instead use a dual MOSFET
H-bridge on a 2.5x4" card to drive them.
Jeff.
