A servo control device according to the present invention performs speed control or torque control for controlling speed or torque of a servo motor based on a speed command or a torque command by an analog input voltage, and performs positional control for controlling a position of the servo motor based on feedback from the servo motor, includes a command switching unit determining that a command voltage by the analog input voltage enters a dead zone of the command voltage which is registered in advance and determined as stopping, and when detecting that the command voltage enters the dead zone, the command switching unit ceases the speed control or the torque control to perform deceleration stop by the positional control by distribution processing of a movement command regarding an actual speed when the speed control or the torque control is ceased as an initial speed.
