Free technology controllers
Overview
The converter has three additional technology controllers.
The three "free technology controllers" have fewer setting options compared with the PID
technology controller described above.
Function description
n = 0 Free technology controller 0
n = 1 Free technology controller 1
n = 2 Free technology controller 2
Figure 6-50
The additional technology controllers allow several process variables to be simultaneously
controlled using one converter.
Example
An 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.
