  • the automated connection controller 30 is programmed to cause the rotational speed of the top drive 12 to decrease when the torque applied to the connection reaches the specified minimum torque level 78.
  • the rate of increase of the applied torque decreases as a result of the decreased rotational speed (at portion 84 of the graph). This reduced rate of torque increase enables more precise control of the applied torque as it approaches the optimum torque level 82.
