Various non-linear effects of valve or drive can be compensated by means of
characteristics. The characteristics are cascaded so that they can be set sepa-
rately.

In order to compensate the direction-dependent controlled-system gain on dif-
ferential cylinders, a characteristic with a gradient that is variable as a function
of direction has been implemented. Fig. 4-14 shows a sample characteristic and
illustrates how the associated machine data works. In practice, only one of the
two gradients is weighted with a factor not equal to 100%. Normally, it is the
gradient that causes the cylinder piston to travel out that is weighted with a fac-
tor of less than 100% (see also Subsection 2.3.1 and Appendix A).
