Abstract

PURPOSE:To improve the flexibility of a device by varying optionally the number of two-phase pulses (PPR), which are outputted from a pulse oscillator (PG), per one rotation in a range smaller than the number of slits of the PG. CONSTITUTION:A pulse processing circuit part 1 converts the two-phase pulse outputs Ai and Bi of the PG to binary data SIGMA1 and SIGMA0, to obtain (0, 1) for the forward rotation of the PG and (1, 1) for backward rotation and (0, 0) for stop. A PPR setting part 4 can set freely a number <=1,023. An integrating circuit part 2 adds or subtracts a value, which is set by the setting part 4, to or from the preceding value held in a DFF2-d in accordance with the timing of the output of the processing circuit part 1. An overflow generated in B1-B10 by addition or subtraction appears in BX-1 and BX. A two-phase converting circuit part 3 converts the binary data BX-1 and BX to two-phase outputs. Thus, the number of the two-phase pulses is varied to an optional number to improve the flexibility of the device.
