Embodiment Construction
[0018] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing and specific embodiment:
[0019] like figure 1 As shown, C0, C1, C2...Cn-1 are respectively the lowest bit, the "1" bit, the "2" bit... to the highest bit corresponding to the complete output of the Gray code data of the absolute encoder. When the absolute encoder rotates once, the total number of high and low level changes of each low bit is twice the total number of high and low level changes of its adjacent high bits, and the upper part of the square wave is 0-(2 n -1) The number is the decimal number corresponding to each group of n-bit Gray codes. A set of data is output every t time, and the step size of the n-bit absolute encoder is 2 n , it rotates once and outputs 2 n group data, its angular resolution is 360 / 2 n , each time the highest bit Cn-1 has a pulse falling edge, it indicates that the absolute encoder completes one revolution, o...
