Abstract

PURPOSE:To achieve a secure return to an origin by generating a control signal at prescribed distance from the rise of fall or the output signal of a limit switch which operates by the movement of a movable part. CONSTITUTION:When an origin return switch is operated, a mechanically movable part moves fast toward an origin. When a dot steps on a limit switch for deceleration near the origin, a deceleration signal XDL rises. In a register 111, a numeral which corresponds to a distance from the stepping point at the limit switch to the origin is stored. After the XDL rises, a counter CNT starts counting. Once the counted value of the counter CNT coincides with the numeral stored in the register 111, the movable part is stopped. Even when the origin is shifted in position, correction is made easily by rewriting the contents of the register 111.
