Resolution and accuracy of absolute encoder

Encoder resolution and accuracy is not necessarily equivalent. Accuracy by the engraved lines, encoder mechanical concentricity, reading response speed, temperature characteristics and other factors determined. If an encoder is sinusoidal groove segments high resolution, then it does not improve the accuracy of, subdivision only improves resolution. Accuracy before and after subdivision does not change, so some high-resolution encoder accuracy depends on the previous line counts.

 In the subdivision precision pre-scribing how much, or how much precision after the breakdown, so some high-resolution encoder accuracy depends on the previous line is how much further subdivided. Absolute encoder digits represent the code disk yardage, because it is in binary code disc (Gray code is the same), So it became two of the accuracy of several parties, such as 12, that is, two of the 12 th 4096.
