Abstract

PURPOSE: To improve a speed response by switching automatically the gain and the time constant of speed control device in response to a load.
CONSTITUTION: With a speed control unit 7, an operational amplifier 700 where proportional integration is processed and an operational amplifier 709 where proportional operation is processed are connected in series. Against the load applied, with light load period switch unit 708 is turned off by the output signal of comparator 715. With heavy load period it is turned on. Thus, the operational amplifier 700 constitutes to switch a gain and a time constant and the operational amplifier to switch the gain with switch unit 708 and diode 706, 707, 713, 714. With the speed deviation signal allowing NR-NF,R2=R3, the gain characteristic formula at light load period mode of normal condition may be IR={(R1+R4)/R2}×{R7/(R5+ R6)}×{(1+SC1(R1+R4)/SC1(R1+R4)}(NR-NF) to select a constant for providing the desired response speed.
