Hi everyone...So I'm fairly new to the world of encoders and I'm trying to understand why a lot of servo drives have options for different count/rev encoders. I come from the world of Mach3, and it would seem that the servo drive could be dumb to that so long as the steps/unit is set correctly in mach3 config.

So the real reason behind my questioning, is I want to add linear encoders to my mill, but I highly doubt the counts/distance will be an even number line on a rotary encoder. so how does that effect the drive? I would think that so long as I have a quadrature encoder and set my steps/distance correctly in mach3 that this would work fine. maybe?
