Abstract: There is provided a speed and position signal generator which operates irrespective of mechanical error, and also operates without any delay of signal transmission. The speed and position signal generator generates A, B phase pulse signals corresponding to a frequency set value and direction setting, and outputs these two phase pulse signals and a Z phase pulse signal corresponding to a teeth number set value, and includes a reference clock generator as a reference, a frequency arithmetic operation circuit, a frequency division circuit for frequency dividing an output phase train from the frequency arithmetic operation circuit, an A, B phase generation circuit for generating A, B phase pulse signals using the frequency division signal, and a Z phase generator circuit for generating a Z phase pulse signal.
