Patent ID: 8736213

Claim:
A motor position controller that inputs command pulse signals that include a first pulse signal and a second pulse signal, each of the pulse signals having change strokes different from each other, and drives a motor based on said command pulse signals, comprising: a pulse form setting signal input portion configured to input a pulse form setting signal that clearly indicates a pulse form of the command pulse signals inputted; a pulse form setting determining portion configured to determine the pulse form by which the command pulse signals are to be interrupted as a pulse form setting, based on the pulse form setting signal inputted by said pulse form setting signal input portion; a position command generating device configured to generate a position command signal from said command pulse signals in accordance with the pulse form setting determined by said pulse form setting determining portion; a motor controlling part configured to supply power to said motor based on said position command signal; and a first conformity determination device configured to determine the conformity of said pulse form setting determined by said pulse form setting determining portion and said command pulse signals.
