PROBLEM TO BE SOLVED: To realize the slewing stop of a 'neutral brake' in a motor driven system slewingly-driven by a motor.;SOLUTION: This control device provides the control of a slewing speed corresponding to the controlled variable of a slewing operation part 28 with a controller 29. In this case, a deviation between an instructed speed value preset corresponding to the controlled variable and an actual speed is found to allow the control of accelerating and braking torque in accordance with the deviation and the output of the maximum braking torque at the time of the controlled variable being zero (a lever being neutral) to lead to motor stop.;COPYRIGHT: (C)2001,JPO
