Mean value generation
If different parameter values result for different radii and path velocities, the best values should be determined via mean
value generation.
Good friction compensation setting
With a good friction compensation setting, "no" contour violations can be detected at the quadrant transitions.
Acceleration-dependent compensation value
If the compensation value proves to be acceleration-dependent, the "friction compensation and adaptation" described below
can be injected in a following step.
11.5.4
Friction compensation with acceleration-dependent compensation value
11.5.4.1
Description of functions
If the compensation value is highly dependent on the acceleration, normally a smaller compensation value must be injected
for optimum compensation with larger accelerations than for smaller accelerations. This dependency can be modeled via the
following adaptation characteristic.
