PURPOSE:To make it possible to input two-phase pulses and to use a position controller, which outputs a speed command, even if a position detecting means for outputting the present position is used with serial data. CONSTITUTION:A serial receiving part 15 receives the serial data from a serial transmitting part 14 of a position detecting means 12 and obtains the present position data of a driven apparatus 2 based on the serial data. A frequency divider means 19 divides the frequency of a reference clock with the frequency dividing ratio set by an operating part 17. A two-phase-pulse generating means 20 generates the pulses having the phase difference of 90 degrees based on the divided-frequency pulses. The polarity of the phase deviation is inverted based on the rotation-direction judging signal from the operating part 17. These parts are provided. Furthermore, the speed of the apparatus is computed based on the present-position data of the driven apparatus 2 from the serial receiving part 15 in the operating part 17. The driving voltage of the driven apparatus 2 is controlled based on the speed, the position command generated in the position-command generating part 26 and the speed signal of the driven apparatus 2 from the two-phase-pulse generating means 20. |
