Although this article is in a hydraulic magazine this info still applies to motors. See the link below about servo motor tuning.

This example is extreme but it makes a point. Get the highest resolution feedback that you can. I have found that poor resolution is a major contributor to making PID tuning difficult. Systems with fine resolution allow one to use higher gains and that will provide much better response and save $$$$. Systems with coarse resolution have very coarse changes in the output which can hurt performance and wear out equipment.
