摘要：
An encoder system includes: a first single-rotation absolute encoder that outputs a first signal corresponding to an angular position of a first rotatable shaft; a power transmission device that transmits the power of the first shaft to a second rotatable shaft with a predetermined transmission ratio; a second single-rotation absolute encoder that outputs a second signal corresponding to an angular position of the second shaft; and a signal processing section that generates data related to the rotation count of the first shaft based on at least the first signal and the second signal.
