Abstract

PURPOSE:To miniaturize a position detecting part and achieve the unification of the kinds of position detectors by multiplying and dividing the command pulses which are inputted in servocontrol for digitally controlling speeds or position with an electronic computer or the like. CONSTITUTION:In a control part 1, moving distances and moving speeds are operated, and command pulses 2 are transmitted by as much as the pulse numbers corresponding to the distances at the pulse rates corresponding to the speeds. These pulses 2 are constant-multiplied by a pulse multiplexing and dividing circuit 10. A position control circuit 3 compares the output pulses of the circuit 10 and the position detection signal 7, and transmits the signal (speed command) corresponding to the error to a speed control circuit 4. In this circuit 4, the speed command and the speed detection signal 8 are compared, and the current corresponding to the error is transmitted to a servomotor 5. When the error of the position and the error of the speed both go zero, the motor 5 stops. The constant of the above- mentioned circuit 10 is determined by the ratio of the rotating angle of the motor 5 and the moving distance of a controlled apparatus 6. Therefore, any gear mechanism is not required for the feedback system and the position detecting part is miniaturized; in addition, the position detectors are unified.
