CIRCULAR ARC TRACK DISPLAY SYSTEM, CIRCULAR ARC TRACK DISPLAY METHOD AND CIRCULAR ARC TRACK DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a circular arc track display system, a circular arc track display method and a circular arc track display device, allowing high-accuracy display of a circular locus with a simple and low-cost configuration without needing a special device combining outputs of two-shaft position detectors.;SOLUTION: The circular locus display device 14 includes: an instruction angle detection part 23 detecting a position instruction corresponding to 45° from a position instruction of a circular arc after input; a circular arc shift detection part 24 detecting whether or not the instruction position corresponding to 45° of the instruction angle detection part 23 is aligned with an ideal position between two shafts; and a position correction part 25 correcting the position instruction of timing and position feedback by the circular arc when the position instruction corresponding to 45° is shifted from the ideal position.;COPYRIGHT: (C)2010,JPO&INPIT
