Yes, I'd guess pulses per rev will be 1024 as that seems to be standard for these motors!As to resolution, you have the natural quadrature count consisting of A pulses per revolution, or using 2 edges for x2 or all four (A+B) edges for x4 quadrature count.
Direction is detected by referng to the status of A pulse compared to B, IOW A would be the amount of pulses and the 1 or 0 level of B detects direction.
Max.
If that is a 1024 line encoder disc, it will take more than a simple slot-opto to read the distinction, it will need the addition of the Moiré grating between head and disc.True, but even without he'll get 1/3deg resolution,. By the time that's geared down, say from 3000rpm to 180deg traverse in 0.5sec, ie 25:1, that's ~25000 counts resolution, far more than needed!
