[Position Compare with non-digital encoders]

Thanks. I was reading the hardware manual for the sine interpolator board. I couldn't follow all the differences in hardware counts, software counts, etc. I take it there is some type of limitation when using a sine encoder, but I can't tell what it will be, and the PMAC manual talks about using 1/4096 of a count for the position compare with a sine encoder. What's all that mean (briefly)?

 

I'm worried that the only time I could fire a pulse is at a zero crossing of the analog encoder, which would limit me to every 5µm in this case. Is this true?

I'm curious if or how the position compare feature feature works with sine encoders and absolute (BiSS-C) encoders?
