A turning drive control unit configured to control driving of the rotation mechanism of a construction machine driven to turn by an electric motor includes a drive command generation part configured to generate a drive command driving the electric motor based on the amount of operation input via the operation part of the construction machine; a rotation speed detection part configured to detect the rotation speed of the electric motor; and a drive command generation part configured to generate a drive command driving the electric motor based on a speed command output from the speed command generation part and the rotation speed detected by the rotation speed detection part. At a time immediately before a rotation stop of the electric motor, the braking torque of the electric motor is limited.
