Abstract

PURPOSE:To always stably and automatically control working solution by detecting instable waveforms and lowering the frequency which is given to a pulse motor even when its feed rate sharply changes. CONSTITUTION:The pressure value is set as a control target by the pressure setting device 508. The pressure detection signals of the pressure detector 501 are amplified by the amplifier 503 and are compared with the setting pressure signals in the comparators 510 and 511. When the range of the detection pressure signals exceeds that of the setting pressure signals, the pulses generated from the pulse generator 506 are applied to the motor driving circuit 517 through the reduction circuit 507. This permits the pressure regulating valve 5 to rotate and the pressure to be controlled for the set point. When the instability of supply pressure is detected in the instability detection circuit 505, the driving pulse frequency of the pulse motor 518 decreases by the reduction circuit 507.
