Abstract (en)
[origin: EP2610049A2] The method involves switching-off a main electric motor (M1) during idle state of a hydraulic press machine. A main pump (P1) is switched-on to boot up a main electric motor in a driving mode. The hydraulic fluid is conveyed through an auxiliary drive unit by the main pump so that the main pump is provided to drive the main motor. The main electric motor is supplied with electric power for reaching a predetermined rotation speed, while switching the main pump to a pumping mode.
