Abstract

PURPOSE:To improve the preision of the detection for arrival of a control quantity at a set quantity, by changing the sigal level width of the control quantity, which detects that the control quantity reaches the set quantity, proportionally to the set quantity. CONSTITUTION:A connection terminl 1 of a speed setter is connected to a signal rectifier 2 and is connected to a divider 4. A connection terminal 5 of a speed detector is connected to an adder and subtractor 6. The adder and subtractor 6 calculates the deviation between the detected speed and an actual speed signal. The divider 4 uses a set signal X and a signal Y corresponding to the deviation between the set value and the actual speed value to operate Y/XX10. When Y/X is within certain range, a relay 15 is turned on. The actual speed signal of the terminal 5 is compared with a certain positive voltage in a comparator 19, and a relay 26 is turned on when the actual speed is higher than the set value. Since contacts 15a and 26a are in series, the output signal indicates that the actual speed reaches a detection range and is higher than a certain value.
