Abstract

PURPOSE:To detect an absolute angle, and also to easily change and increase a set detection angle, by detecting an angle as a BCD code signal, when detecting the angle. CONSTITUTION:A detector 1 detects a working angle by a BCD code signal divided into 360 per its 1 rotation, and also whenever it is divided, a timing pulse whose width is shorter than signal width of the BCD code is outputted. When the timing pulse rises, the BCD code is latched 2, and is sent to a memory 4 having a service interruption holding function, through a data selector 3. In case of reoperation after service interruption, a memory angle before stop is selected by a signal of a flip-flop 7 by resetting 6 the electric power supply. When signals which are larger than (a) and smaller than (b) are selected by the first comparator 8 and the second comparator 9, respectively, and an AND10 is taken, a relay 11 is operated by an angle X of a <=X<=b.
