To achieve further reduction in power consumption in the case where the power storage residual amount of a power storage device becomes low.SOLUTION: A system includes an electric motor driven by power from a power storage device, and a main hydraulic pump driven by the electric motor, and it is for controlling a work machine driven by a hydraulic oil supplied from the main hydraulic pump. The system includes a controller. The controller detects a power storage residual amount of the power storage device, and it controls the timing of decelerating the rotational frequency of the electric motor to predetermined idle rotational frequency, based on the detected power storage residual amount of the power storage device.SELECTED DRAWING: Figure 1

    【課題】蓄電装置の蓄電残量が低くなった場合、さらに電力消費の低減を図ること。【解決手段】蓄電装置からの電力によって駆動する電動モータと、電動モータによって駆動するメイン油圧ポンプとを備え、メイン油圧ポンプから供給される作動油によって駆動する作業機械を制御するためのシステムであって、コントローラを備える。コントローラは、蓄電装置の蓄電残量を検出し、検出した蓄電装置の蓄電残量に基づいて、電動モータの回転数を所定のアイドル回転数へ減速させるタイミングを制御する。【選択図】図1
