For a more complex control, the actuator can implement a characteristic curve, defined
through
three custom control points
, i.e., three pairs of values of the form (
x
,
y
). This
lets the definition of custom curves, such as:
Figure 13.
Custom Control Curves.
In case the first and last points do not correspond (respectively) to values 0% and 100%,
the characteristic curve will be defined as follows (see Figure 13 and Figure 14):
For
control
values lower than that of the first point
, the actual regulation
value will be 0%. For example, in Figure 14 all control values under 20% imply
a regulation value of 0%.
For
control values greater than that of the last point
, the actual regulation
value will be 100%. For example, in Figure 14 all control values over 80% imply
a regulation value of 100%.
