Pzd2, Reference Value/Actual Value - BONFIGLIOLI Vectron ACTIVE CUBE Manual

13.4.5
In the PZD2, the master gives its reference value to the frequency inverter in the out-
put data set and gets information back on its actual value in the input data set.
The use of the reference/actual value channel depends on the configuration setting
(control system). The actual value is generated from one of the sources according to
the control system.

The distinction is made via the setting of parameter
