#186392 - trick question? Responding to: ???'s previous message |
Many years ago I had an encoder (on a motor) that provided an index and quadrature for 512 discrete positions. The index was fixed, so it persisted through power cycles. Do you consider that one absolute or merely incremental
if all you get is "index and quadrature" (2 wires + Vcc/Gnd) the encoder is not absolute any more than a stopped watch is right twice a day. If, however the 512 pos encoder has 9 wires + Vcc/Gnd is it asbsolute and incremental if you only use 2 wires Erik |
