A control method for controlling a cylinder actuator comprising a chamber on the rod side of the cylinder actuator and a chamber on the head side of the cylinder actuator, the cylinder actuator being configured for actuating a ram of a press, the control method comprising: - providing an accumulator connected only with said chamber on the rod side of the cylinder actuator; - actuating a motor group with which a pumping group consisting of a 2-quadrant pump that is directly fluidly connected via a shut-off valve to said chamber on the head side of said cylinder actuator by a fluid-dynamic circuit for a feeding fluid and having an active rotation and a passive counter-rotation is associated; - reciprocating said cylinder actuator between an active working stroke during said active rotation and a return stroke during said counter-rotation, wherein the movement of the cylinder actuator in the phase of descent is opposed by the pressure in the chamber on the rod side of the cylinder actuator that is fluidly connected to said accumulator; - controlling by said motor group and pumping group (101, 102) at least one of said active stroke and/or return stroke during at least one of said active rotation and/or said counter-rotation; - detecting by means of a pressure transducer the reaching of a programmed pressure value to which a pressure reducer is set, so as to control the pressure inside the accumulator wherein said controlling comprises: - controlling micrometrically an active working speed of said active stroke and/or a return speed of said return stroke; and - maintaining said cylinder actuator in a floating condition between said active stroke and said return stroke. - providing an accumulator connected only with said chamber on the rod side of the cylinder actuator; - actuating a motor group with which a pumping group consisting of a 2-quadrant pump that is directly fluidly connected via a shut-off valve to said chamber on the head side of said cylinder actuator by a fluid-dynamic circuit for a feeding fluid and having an active rotation and a passive counter-rotation is associated; - reciprocating said cylinder actuator between an active working stroke during said active rotation and a return stroke during said counter-rotation, wherein the movement of the cylinder actuator in the phase of descent is opposed by the pressure in the chamber on the rod side of the cylinder actuator that is fluidly connected to said accumulator; - controlling by said motor group and pumping group (101, 102) at least one of said active stroke and/or return stroke during at least one of said active rotation and/or said counter-rotation; - detecting by means of a pressure transducer the reaching of a programmed pressure value to which a pressure reducer is set, so as to control the pressure inside the accumulator wherein said controlling comprises: - controlling micrometrically an active working speed of said active stroke and/or a return speed of said return stroke; and - maintaining said cylinder actuator in a floating condition between said active stroke and said return stroke. - controlling micrometrically an active working speed of said active stroke and/or a return speed of said return stroke; and - maintaining said cylinder actuator in a floating condition between said active stroke and said return stroke.
