摘要
A disclosed multiple rotating absolute encoder comprises an encoding plate with a first pattern and a second pattern formed thereon, a first detection unit for reading the first pattern and outputting an information in one rotation of the encoding plate, a second detection unit for reading the second pattern and outputting a first rotation information of the encoding plate, a calculation unit for calculating a second rotation data based on the information in one rotation and the first rotation data, a selection unit for monitoring a rotation speed of the encoding plate and selecting either the first rotation data or the second rotation data in accordance with the rotation speed, and a data calculation unit for calculating rotation information of the encoding plate on the basis of either the first rotation data or the second rotation data selected by the selection unit and the information in one rotation.
