Encoder error！

incremental encoder error is composed of three types: 1) quantization error, 2) instrument error, 3) cycle interpolation error (if the encoder is so equipped). 
Quantization error exists because the encoder cannot indicate motion occurring within one resolution quantum at transition points. This is the highest frequency error component and repeats every quantum of input motion. In a perfect encoder with no mechanical, optical encoder or electronic encoder deviation from the ideal, the correct angular position encoder of the input shaft for a given readout is defined as the angular position midwaybetween the transition from the next lower readout to the transition for the next higher readout,with the maximum erro+1/2 of angular rotation between two successive bits.for example,a rotary incremental encoder that generates 360 pulses per revolution has q quantization error of 1/2 angular degrees
