About the concept of "absolute" encoder ！
Changchun Rongde Optics Co.,Ltd. Release time：2016/7/20 Browse：589About the concept of "absolute" encoder of "deliberately confusing" and misunderstanding
About absolute encoder, a lot of people's understanding or remain in the "blackout" position to save this concept, this is one-sided and there are limitations, "Absolute" encoder is not just the problem of power failure, the receiving device for real "absolute" refresh significance in terms of internal or external encoder, the independence of each position, uniqueness, does not depend on the previous reading of "absolute encoder", the definition of "absolute" and its data reading the market is still ambiguous, for some businesses this will be the concept of "deliberately confusing":
A confusion: the "absolute mode" and the absolute encoder receiving device of "absolute" confusion. Receiving device "absolute" refers to the receiving unit does not require continuous accumulation counts all locations for a device origin "absolute" mode, this mode is in fact by its incremental encoder counts accumulating means + + memory cells, when the same device can provide "absolute" location information, and it is an absolute encoder "absolute encoder" is not a concept, and the possibility of error count accumulated error of its existence, the counting device power failure probability, high-speed the possibility of failing to respond count.
Confuse the two: the absolute single-turn encoder + internal and external counting device and accumulating the absolute value of the true meaning of true multi-turn encoder confusion. Absolute value meter lap + lap counting means, it is an absolute value of less than 360 degrees, but after more than 360 degrees, its location is not "independent", "unique", and it is relying on an internal or external count to determine how much circle lap absolute position information, such internal or external "counting device", and incremental encoder counting means + nature + battery memory is the same, any error count or counting device work when the power supply instant failure will cause errors and can not determine the cumulative, resulting in absolute deceptive false information. The real absolute multi-turn encoder, in addition to the location of 360 degrees are absolutely unique and, in the more than 360 degrees and continue to drive the mechanical gear absolute value encoder and still provide "independent", "unique", not dependent in previous data read refresh accumulated absolute encoder. In fact, from "absolute" is, by definition, in front of the kind of single-turn absolute count + accumulation means "false multi-turn absolute encoder", it can not then told "absolute multi-turn encoder", although in within 360 it is absolute, but the operating range of more than 360 degrees, it is no longer "absolute encoder" the.
