How to calculate the incremental encoder resolution?

The resolution of the optical introduces how to calculate the incremental encoder? The resolution of the photoelectric encoder is produced by the encoder shaft rotation week number fundamental period of the output signals, the pulse number/roll ( PPR) 。 The pervious to light on the encoder gap is equal to the resolution of the encoder, the number of cracks on the encoder, the more the higher the resolution of the encoder. In industrial electrical transmission, according to the different application object, the choice of resolution is usually in the 500-6000 PPR incremental photoelectric encoder, up to tens of thousands of PPR. Ac servo motor control system usually choose a resolution of 2500 PPR encoder. In addition to logical processing of photoelectric conversion signal, can get 2 times or 4 times the frequency of pulse signal, so as to further improve the resolution. Shanghai optical co. , LTD. Is a collection of industrial encoder and high precision coupling of research and development, manufacture and sales for the integration of high-tech enterprises, the main products are encoder and coupling, anchor displacement sensor. A: and the relationship between accuracy of a rotary encoder resolution: the number of pulses encoder is what?
