This lag can be up to 5 ms, then the velocity overshoots badly so that the position can catch up. Take a look at :
http://pico-systems.com/images/compare_encoders.png and http://pico-systems.com/images/compare_encoder2.png In these traces, the red line is the CUI encoder, and the white line is a HEDS optical encoder, set to appropriate gains so the traces match. One picture seems to show the lag better, the other seems to show the different peak velocities better. Anyway, it makes servo tuning a bit difficult with this behavior.
