Free technology controllers
Additional PID controller
The inverter has three additional technology controllers.
When compared to the main PID technology controller, the free technology controllers have
somewhat fewer setting options, see also PID technology controller (Page 266).
n = 0 Free technology controller 0
n = 1 Free technology controller 1
n = 2 Free technology controller 2

You can find the complete function diagram 7030 in the List Manual.
The additional technology controllers allow several process variables to be simultaneously
controlled using one inverter. An example is a HVAC system with heating and cooling valves
to process the air:
● The main controller controls the speed of the fan drive.
● The additional technology controllers control the cooling and heating via the two analog
outputs available.
