Figure 7-36 Technology controller structure with parallel components
where
Other controller variants are also possible:
● PI controller by switching out the derivative component (rate time T
V
: p2274 = 0)
● PD controller by switching out the integral component (integral time T
N
: p2285 = 0)
● Proportional controller by switching-out the integral and derivative components (p2274 =
0; p2285 = 0)
Note:
In the factory setting (p2252.1 = 1), the integral component is not dependent upon the
proportional gain (p2280). In this case p2285 is the integration time constant T
I
. If p2252.1 =
0, p2285 will become the integral time T
N
, with the result that the following applies for the
integral component:
A further connector input (p2289) is available at the controller output for pre-control or
switching in fault values. The signal is then routed via a limit (p2291/2).
The technology controller has a dedicated enable binector input (p2200). To avoid abrupt
changes in the output signal, an output ram can be defined by means of a ramp-up/ramp-
down time (p2293).
Note:
In the factory setting p2252.2 = 1, the output will be set to 0 as soon as the enable is lost
(p2200 = 0). In order for the output signal to be fed back via the output ramp, p2252.2 = 0
must be set.
The output signal (r2294) can then be scaled via the connector input p2295 before being
made available as a connector output for downstream connection.
