Abstract
PURPOSE:To perform high-accuracy position detection up to high-speed rotation by providing a circuit which performs electric interpolation and a circuit which performs no electric interpolation and selecting the output of position detection data according to the rotating state of a rotary shaft, etc. CONSTITUTION:Detection signals Sa and Sb which are outputted by an optical or magnetic detection part 1 and 90 deg. out of phase with each other and a reference point output signal S are converted by a pulse converting circuit 11 into pulse signals Pa and Pb, and Pz. Then a logic circuit 14 generates periodic two-phase pulse signals Pa' and Pb' with resolution four times as high as the resolution of the pulse generating circuit 11 from pulse signals P1, P2, and Pz outputted by the pulse generating circuit 11, and pulse signal P1, P2...P6 outputted a pulse generating circuit 13. A selecting circuit 15 selects the pulse signals Pa, Pb, and Pz outputted by the circuit 11 or the pulse signal outputted by the logic circuit 14 to generate outputs PA, PB, and PZ.
