Abstract

PURPOSE:To improve reliability, by putting magnetic pole detecting signal together with original point signal, through time division, and by saving a signal transmitting means. CONSTITUTION:The position signals A, B of the rotation or the like of a motor with an encoder are turned into the selecting signals A, B of a multiplexer 1, and other signals C, U-W are selected to generate the output as phiC. Then, via a cable or the like, and via a line receiver and a disconnection detecting means, or the like, the signals phiA-phiC come to the signal receiving side and are introduced into a signal receiving side circuit. The input signals phiA-phiB are turned into + or -FB pulse by a differentiating circuit 3. Besides, the input signals phiA-phiB are turned into the selecting signals of an addressable latch 2, and the input of the signal phiC to the data input terminal D is provided, and the keying signal of a gate G is produced from signal delayed from the + or -FB by 1 clock time. Besides, the signal + or -FB is passed through a NAND 5 and a J-K flipflop 4, and the signal G is applied to said latch 2.
