In most cases accuracy is more important value than resolution. Accuracy is more difficult to measure because it largely depends on mechanical load characteristics and dynamics. In ideal conditions the accuracy is very close to resolution but in most of practical cases the accuracy is 5 to 10 times less than resolution. I.e. 1000 PPR encoder can be expected to provide 1/400 to 1/800 revolutions accuracy. | In most cases accuracy is more important value than resolution.
