In a state where a slewing stop operation is input, in a first state where a slewing command value is equal to or greater than an actual slewing speed (period TA), a drive unit (203) stops outputting a torque command value, and a free-run state occurs. In the first state, a command value calculation unit (202) decreases the slewing command value at a first inclination (K1). Meanwhile, in the state where the slewing stop operation is input, in a second state where the slewing command value is less than the actual slewing speed (period after time t2), the command value calculation unit (202) decreases the slewing command value at a second inclination (K2) that is gentler than the first inclination.
