Abstract
A control device for safely controlling an electrical motor during decelerating and stopping operations of the motor. The control device includes a control part for controlling the decelerating and stopping operations; a monitoring part for monitoring the operations of the electric motor; and a judging part for judging whether the velocity of the electric motor monitored by the monitoring part is abnormal while the control part controls the motor so as to decelerate and stop the motor. The judging part forcibly cuts off power to the electric motor, via a circuit breaker, when the judging part judges that the velocity of the motor is abnormal.
