3.5.8 4-9* Directional Limits
The directional limits functionality allows to specify
different torque and speed limits for different
combinations of torque application direction and rotation
direction. For example, see
. In the
illustration, quadrants 1–4 show different combinations of
rotation direction and torque application direction, and the
parameters that act in different quadrants.
