Please note that the controller structure of the technology controller differs from the standard
technology controller structure described below, which is standard in some sources. To
enable comparison, the corresponding conversions have been specified:

Other controller variants are also possible:
● PI controller by switching-out the derivative component (rate time T
● PD controller by switching-out the integral component (integral time T
● Proportional controller by switching-out the integral and derivative components (p2274 =
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
0, p2285 will become the integral time T
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 immediately when 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.
