Re: How much PPR do you use on your encoders?

Yeap then the OP is confused.

Counts per revolution might be 4x higher because of the decoder, but cycles per revolution as you say is the same as PPR.

The only way this might not be the case would be having part of the quadrature decoder in the encoder and this is clearly not the case with most U.S. Digital encoders. At best the U.S. Digital encoders have some buffer functions in general.

This was why I posted in another topic the PPR not the CPR or anything else. Too confusing.
