12.9 Controller configuration (controller type) and controller action )
The controller configuration is automatically carried out during selection of the application related mode of operation.
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 circumstances, these can be individually adapted.
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 (
P
roportional component, proportion of the absolute deviation)
I
control (
I
ntegral component, proportion of the sum of all deviations)
D
control (
D
ifferential 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.
P-component = reaction time
Setting range 0-200 %
smaller = more slowly
bigger = faster
I-component = accuracy,
correction time
Setting range 0-200 %
smaller = faster
bigger = more slowly
D-component = stability by
slower
correction time
Setting range 0-200 %
smaller = faster
bigger = more slowly
Integration time = correction time
Setting range 0-200 %
smaller = faster
bigger = more slowly
