A robot controller configured to be able to mitigate the effect that an emergency stop may have on a robot is disclosed. The robot controller includes: a load detection unit which detects the load of a motor for driving each individual articulated axis of the robot; a speed detection unit which detects an axial speed at each individual articulated axis of the robot; a cause-of-stop identifying unit which, when an emergency stop of the robot occurs, identifies a cause of the occurrence of the emergency stop; and a recording unit which records the cause of the occurrence of the emergency stop by associating the cause with the axial speed or the load of the motor. The robot controller may further include a display unit which displays information representing the state of occurrence of the emergency stop of the robot.
