Abstract
A controller includes a stop command unit for stopping the motion of the robot when a person comes into contact with the robot, and a speed limiting unit for limiting the operation speed of the component driven on the drive axis. A variable calculated from the position of the component on the drive axis and the range of the variable in a state where the person is caught by the robot are determined in advance. The speed limiting unit acquires the variable from the output of a position detector and controls the operation speed of the component to a predetermined speed limit or lower if the variable is within the range.
