### How to calculate encoder resolutionLinear Motion Tips

For example if a 2500 PPR encoder has a maximum mechanical speed of 3000 rpm a frequency response of 100 kHz and is used with X1 encoding its maximum electrical speed will be 2400 rpm. In this case the maximum electrical speed (2400 rpm) is less than the maximum mechanical speed (3000 rpm) so electrical speed is the limiting factor.
