摘要： In a swing control device installed in an electric rotary excavator (a construction machine), when a leading edge or a trailing edge of a lever signal is sharp due to a quick operation of a swing lever, a gradient as a rise time Ta1 or a fall time Tb1 is provided to the leading edge or the trailing edge of the torque output and the acceleration that are output based on the lever signal so as to somewhat ease the edge. With the arrangement, an impact in acceleration or deceleration of a rotary body can be suppressed. Specifically, a gradient in the acceleration operation is provided such that the rise time Ta1 becomes 0.15 seconds or more, while a gradient in the stop deceleration operation is provided such that the fall time Tb1 becomes 0.1 seconds or more.
