Abstract

PURPOSE: To make it possible to supervise the rotational speed of a rotator automatically by detecting and displaying the deviation between a command rotational speed from a computer and the actual speed of the rotator by percentage and by sending an abnormality signal when the deviation exceeds the preset range.
CONSTITUTION: As the rotational speed command of a computer is supplied to DC servomotor 1, the frequency division of frequency dividing circuit 3 is set according to the command and as DC servomotor 1 rotates, rotational extent detector 2 outputs pulses of a frequency proportional to the rotational speed, to frequency dividing circuit 3. With the pulse of timer 5, up-down counter 4 is put into operation for a prescribed time and starts counting from 100 according to frequency division pulses; and the speed deviation is detected and displayed 6 by percentage and it is also compared 7 to allowable deviation value 8, so that when the count value exceeds the allowable range, abnormal rotation speed signal (d) will be sent out.
