Abstract: PURPOSE: To make initialization of a moving mechanism by detecting a plurality of the dividing points of the moving range of the mechanism, counting the encoder output pulses until the reference point of the encoder is detected, and determining the position of the moving mechanism through comparison of the result from counting with a set value for each dividing point. CONSTITUTION: The encoder output pulses pdef are counted until the reference pulse signal SP of an incremental type encoder is detected from the positions D1, D2 where dividing points on a light shutoff plate installed on the output shaft as a moving mechanism passes a photo-sensor. Because the reference points have different spacing from that of the dividing points, the number of pulses pdef increases by Δpdef every two turns of encoder. The setting is made so that the number of output pulses differs from time to time over the rotating range of the output shaft, and the number of pulses pdef corresponds on 1:1 basis to the absolute angle of the output shaft at all times.  In the return motion to the point of origin, the number of pulses pdef is reset to zero, and when the output shaft is rotated to detect the reference point of the encoder, the number of pulses pdef at that time is read, and the absolute angle of the output shaft is determined from the positional relationship between the dividing point and reference point.
