PURPOSE:To shorten a regulating work time by regulating the displacement of a slit plate so that the output waveform of a rotary encoder becomes the prescribed corresponding relationship to the stationary point of a step motor in a counterelectromotive force waveform. CONSTITUTION:An output shaft 5 is rotated at the certain prescribed speed by the secondary rotary force, the counterelectromotive force waveforms 3A, 4B of the exciting windings 3, 4 are observed, and compared with the output waveform C form a rotary encoder 2 simultaneously indicated with them. Thus, the angular position of the slit plate 13 is regulated and the waveform C of the encoder 2 is regulated corresponding to counterelectromotive force waveforms 3A, 4B, thereby unitarily corresponding the stationary angle position of a step motor 1 and the detecting angle position from the encoder 2. |
