5.8.2 Operating mode preselection

the switching of the operating mode during an operating mode change, depending on the
process requirement. Only the last operating mode preselection is confirmed by the control-
ler.
You can deactivate the function, although it is configured. To do this, connect a "1" signal to
input IDi1.
