Abstract

PURPOSE: To match the rotation of a driving motor with the start position of a controlled object when electric power is applied, by connecting the driving motor to a correcting motor through a differential gear.
CONSTITUTION: When the electric power is applied, an initial condition set signal is supplied from a command unit 1 to an initial condition set circuit 20. Then, the circuit 20 produces a pulse signal corresoponding to the phase difference between a position detector 12 and a rectilinear position detector 18. The pulse signal is applied to OR gates 2,5 or OR gares 3, 4. The phases of output signals of digital phase modulation circuits 6, 7 are led or delayed depending on the number of pulses applied to the OR gates 2W5. The quantities of the variations in the phases of the output singals are detected by phase difference detection circuits 8, 9. DC signals dependent on the quantities are applied to speed control servo-units 10, 11 to rotate the driving motor and the correcting motor. The output shafts of these motors areconnected to each other through an input gear of a differential gearing unit 14. Thereby, the rotation of the driving motor is matched with the start position of the controlled object 17
