Zusammenfassung:	PURPOSE: An actuator control device of a press machine using a servo motor is provided to reduce a working flow rate by selectively and precisely controlling only necessary hydraulic pumps. CONSTITUTION: An actuator control device of a press machine using a servo motor comprises an actuator(10), a hydraulic tank(20), an accumulator(30), and first and second hydraulic pumps. The actuator moves a press up and down. The hydraulic tank holds a certain amount of working fluid. The accumulator provides hydraulic pressure to operate the actuator. The first and second hydraulic pumps supply working pressure to the accumulator from the hydraulic tank. The first and second hydraulic pumps are operated by the servo motor.
