Abstract

PURPOSE:To enable a constant-speed control of small error to be performed even if the designated speed is largely changed, by providing a circuit means to provide friction-compensating voltages made to correspond to respective speed-designating signals. CONSTITUTION:When an R-SFF12 is set by the scanning start pulse, a switch 11 is closed, and a speed-designating signal is outputted from a speed-setting circuit 10. Said speed-designating signal and the speed feedback signal are added by an adder 5 together to output an error signal. On the other hand, the friction-compensating signal outputted from a friction-compensating circuit 9 according to the speed- designating signal is added by an adder 7 to the error signal from the adder 5 amplified by an amplifier 6 in voltage, and fed to a DC motor 1 through a current amplifier 8. Thereby, proper frictional resistance compensations can be performed for respective designated speeds.
