Abstract
PURPOSE: To obtain an instantaneous speed signal which is positive or negative depending on the direction of motion of a moving body, by generating a signal of frequency corresponding to the speed of the moving body and by detecting the change in the signal within a prescribed time and the direction of motion.
CONSTITUTION: When a motor is rotating, signals different in phase by 90° from each other are generated by an encoder PSG and amplified at AMP1, AMP2. The amplified signals are shaped to rectangular waves at VC1, VC2. The rectangular waves and the output of a direction detecting circuit WD are applied to a logical control circuit LCC, which regulates switches SW1WSW4, regulates another switch SW5 by the same signal as a position pulse signal and regulates still another switch SW6 by a signal delayed by a prescribed time in comparison with the signal for the switch SW5 to hold speed detecting signals at C1, C2. The difference between both the sampled and held signals is detected, thereby producing the speed signal.
