Operating Instructions ACU
18.3 Technology controller
The technology controller, the behavior of which corresponds to a PID controller, is available as an
additional function in configuration 111, 211, 411, 511 and 611. The connection of reference and
actual value of the application with the functions of the frequency inverter enables process control
without further components. In this way, applications such as pressure, volume flow or speed
control can be implemented easily. The configuration of the reference percentage source and the
assignment of the actual percentage source are to be considered.

Actual Percentage Source 478 is:
- Analog signal at multifunction input:
- Frequency signal at digital input:
Displays the current actual controller
value:
Actual Percentage Value 230
For the reference value, the technology controller also demands the assignment of an analog
application figure with parameter Actual Percentage Source 478. The difference between reference
and actual value is used by the technology controller to control the drive system. The measured
actual value is mapped via a signal converter onto the input signal of the reference percentage
source.
