Abstract: A motor control device includes a control unit and a generation-method changer. The control unit generates a driving signal for driving a motor in accordance with a command signal and an encoder signal and outputs the generated driving signal to the motor, the command signal being a signal for setting the position of a moving part connected to the motor to a target position, the encoder signal indicating the position of the motor detected by an encoder. The generation-method changer changes a method used by the control unit to generate the driving signal in accordance with a position sensor signal indicating a detected target position that is the target position detected by a position sensor mounted on the moving part.

Abstract: A motor driver drives a motor that controls a position of an object based on a command from a controller. The motor driver includes: a correction command output part that outputs a correction command for correcting a position of the motor based on a position of the object detected by a displacement sensor that detects the position of the object; and a position controller that outputs a drive signal for driving the motor based on the command from the controller and the position of the motor detected by an encoder that detects the position of the motor, or based on the correction command and the position of the motor detected by the encoder.
