  • This can for example be analogous to a non-motorized hand screwdriver, which is rotated to tighten a screw by the operator in one direction and to loosen a screw in the other direction.
  • speed or torque with the same deflection behavior of the user depending on the direction of rotation for example, to provide a higher torque for screwing a screw than for unscrewing the screw.

In a sudden cancellation of the torque can be closed on a destroyed, such as torn screw. In both cases, an error may be output, for example as a message on a display or via a warning lamp.
  • the change in torque can also be detected without a torque measurement by rotation rate change, since the user builds up a counter torque to the tool torque, which behaves sluggish with rapid torque changes.
