ミツタ機構。 In a slide table limiter mechanism that detects the position of the slide table and limits the movement range of the slide table by intermittent control signals supplied to the slide table drive unit from a servo circuit, etc., these are placed at both ends of the slide table's movement range. a limit switch that detects the position of the slide table; a switch that is inserted in the front stage of the drive section that connects and disconnects the control signal; a comparator that determines the polarity of the control signal; an output state of this comparator and an output state of the limit switch. A limiter mechanism for a slide table, comprising: a logic circuit for controlling on/off of the switch according to the switching on/off of the switch.
