常速度検出器。 A remote-controlled speed setting device that can remotely control a speed setting device that provides a speed setting signal, a speed control circuit that obtains the speed setting signal and an actual speed feedback signal and generates a speed control signal, and a motor drive that drives an electric motor. In a speed control device equipped with a circuit, the actual speed at that time is memorized when the speed is constant, and the speed control device is set to operate at a time slightly slower than the travel time of the remote-controlled speed potentiometer during acceleration/deceleration, so that the speed controller can be set to Abnormal speed detection of a speed control device, characterized in that a speed operation determining means for determining the operating state at predetermined intervals and a comparing means for giving an operation difference output thereof are provided, and an abnormal speed detection signal is provided from the output of the comparing means. vessel.
