  • Patent number: 4528491
    Abstract: Displacement table data, which consist of pulse number data for N individual displacement divisions which altogether constitute a given rotational displacement of a pulse motor, are stored in a memory so that the sum of pulse numbers stored in the individual divisions may be equal to a given pulse number corresponding to the displacement of the pulse motor. Pulse period table data, which consist of pulse period data for determining the speed of the pulse motor for divisions corresponding in number to the number of divisions of the displacement table data, are stored in another memory. The pulse motor control is effected by causing generation of pulses corresponding in number to the pulse number data for the individual displacement divisions of the displacement table and having pulse periods for the individual divisions of pulse period table, and by executing the generation of pulses for the successive divisions.
