摘要：
In a method of detecting the absolute position of a servo control system which is controlled according to, for example, a numerical control program, the absolute position of an operating shaft is detected with a high accuracy from an output corresponding to a predetermined rotational ratio between a resolver (106) and an absolute encoder (110) which rotate together with a servo motor (105), making it possible to rapidly stabilize any change of the absolute position of the operating shaft occurring when the servo control system is in an abnormal state.
