TURNING DRIVE CONTROL APPARATUS AND CONSTRUCTION MACHINE INCLUDING THE SAME
First Claim
1. A turning drive control apparatus that controls a drive of a turning mechanism of a construction machine driven to turn by an electric motor, comprising:
- a drive command creation part that creates a drive command to drive said electric motor based on an amount of operation input through an operation part of the construction machine;
a turning motion detection part that detects a turning motion of said turning mechanism; and
a drive command correction part that corrects said drive command, when a turning motion in a direction opposite to a turning operation direction input to said operation part is detected by said turning motion detection part, to suppress the turning motion in the direction opposite to said turning operation direction in response to a degree of the turning motion in the direction opposite to the turning operation direction.
