Abstract
PURPOSE:To perform highly accurate angular control by rotating a motor at the maximum speed during the period the deviation value from the objective value is larger than a specified value and by decreasing the rotation speed in proportion to the amount of decrease when the deviation value becomes lower than a specified value. CONSTITUTION:When an analog signal is given at an input point 1, the polarity is sensed by a polaritt sensor 2, and a start command for a pulse motor 6 is given to a driver 3. At the same time, the analog signal is rectified by a rectifier 4 which sends out the output in proportion to the absolute value up to a specified value of the input signals and is saturated when the input signal exceeds a specified value. The output is fed into the driver 3 through a V/F converter 5. A signal from a rotation-angle sensor 7 comprising a potentiometer and the like is negatively fed back to a comparating point 9. In this constitution, since the pulse motor 6 operates at the maximum speed when the deviation exceeds a specified value, and operates at a lower speed when deviation is small, the highly accurate angular control can be performed.
