Abstract

PURPOSE: To enable the positioning control with best time efficiency, by adding a simple circuit not requiring adjustment and selection.
CONSTITUTION: The system is constituted by adding the 1/2 operation unit 13, setter 14, coincidence detection circuit 7'. The setter 14 with this constitution is set so that the deceleration start position Ld is a half the moving distance Lxo at start plus low speed moving distance Ll. Thus, the positioning start instruction operates the distance between the present position of the moving unit and the direction objective position, the absolute value Lxo for the value is preset at the preset subtraction counter 5, and the direction of movement is discriminated for the sign +, - with the direction discrimination circuit 11. The moving unit moves toward the objective with the end of setting. When the moving distance L at high speed moving is not smaller than 0, the detector 7 is operated and the coincidence detector 7' is operative after that. When L is not greater than 0, the detector 7 is operated and the detector 7' is operative. Accordingly, in either case, the deceleration instruction is made with the AND signal between the detectors 7 and 7', then the deceleration instruction having efficient positioning can be delivered.
