Abstract:
A motor controller is configured to judge whether or not the amount of displacement of a driven body after the direction of movement of the driven body is reversed, exceeds a predetermined threshold value, and whether or not the amount of displacement of a motor after the direction of movement of the motor is reversed, exceeds another predetermined threshold value. When the amount of displacement of the driven body exceeds the threshold value, or the amount of displacement of the motor exceeds a second threshold value, the correction of the commands to the motor is terminated.
