16.3 Technology
Controller
The technology controller, the behavior of which corresponds to a PID controller, is
available as an additional function in configuration 111, 211 and 411. 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 con-
figuration of the reference percentage source and the assignment of the actual per-
centage source are to be considered.

For the reference value, the technology controller also demands the assignment of an
analog application figure with the parameter

. The dif-
ference 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.
