cut something out, sorry Laurentino <g>
> By the way, how can they drive a motor and receive feedback from it 50
times per rotation using only two wires ??? (have I seen this wrong?)
You have seen wrong, I disassembled my Unit because the motor´s were not
running, I noticed that there are two things "connected" to the build in
motors:
1) the power wire, connected by wire with a plug
2) directly on the pcb is photoelectric barrier around a perforated wheel
driven by the motor I think thats how the measure the revolutions (There are
two mounted, one for each motor)
If you want to take a closer look, be careful as the pcb is repressed by one
photoelectric barrier, don´t break it!
