    • An analog error signal is received from a machine tool position sensor. Its magnitude is sensed by a comparator circuit including an operational amplifier and a digital output level is generated when a particular analog voltage level is sensed. The digital output level resets the position sensor to restore the analog output signal and the comparator circuit to their initial state. A reset circuit, including two monostable circuits, generate a delayed reset pulse to the input of the comparator to reset its output if the analog input signal fails to do so. Forward and reverse directional circuits including NAND logic gates are connected together in parallel to the comparator output and conditioned by forward and reverse reference signals to convey the digital output from the comparator when the machine is moving in the direction to which the comparator has been preconditioned.

    • A controller receives a voltage signal as an input signal. A first resistor (21) is provided in a positive electrode side path (51) and a second resistor (22) is provided to connect on the path (53) between the positive electrode side path (51) and a negative electrode side path (52). The first resistor (21) and the second resistor (22) act as voltage dividing resistors, the voltage of the voltage signal is reduced in half and the reduced voltage signal is input to a microcomputer (10). Reading maps for voltage signal corresponding to ratio between the assumed input maximum voltage and the reduced input voltage for each input voltage pattern are preliminarily stored in the microcomputer (10). The maps are selected by a first changeover switch (13) and a second changeover switch (14) of the microcomputer (10).

    • A numerical positioning control system using a single feedback transducer which is coupled to the controlled machine axis. The transducer has a relatively small scale factor, substantially less than the total amount of travel of the controlled machine tool axis, and is monitored by a cycle control unit which generates output signals so as to control the phase of a phase varying means such as a variable phase digital counter. The output of the variable phase digital counter then represents a second phase varying signal which has a scale factor larger than the scale factor of the feedback transducer. Input data is fed into the system and is used to vary the phase of digital counters which are then phase compared with the phases of the feedback transducer and the phase varying means. The results of these comparisons are used to control the driving means which ultimately operate to move the controlled machine axis in a direction and at a speed related to the difference between the actual position of the controlled machine axis and the desired position as indicated by the input data.
