Controller con

guration
The
“
controller con
fi
guration
”
is automatically carried out during selection of the application related
mode of operation (Base setup). The factory presets in accordance with the mode of operation are
based on many years of experience, which is suitable for many applications. Under special circum-
stances, these can be individually adapted (

).
Type of control
The type of control determines the method with which the controlled value behaves in
case of a difference between the target and current values. For this, the control
technology has standard algorithms, which consist of a combination of three methods:
Selection P, PID:
•
P
control (Proportional component, proportion of the absolute deviation)
•
I
control (Integral component, proportion of the sum of all deviations)
•
D
control (Differential component, proportion of the last difference)
With pure P controllers (controller type
P
), the following described settings do not have any function.
If needed, the most suitable combination for the respective control system can be determined from these
proportions.
