10.3.2 Inversion of outputs
Any output can be inverted.
Main menu > Commissioning > Settings> .... or
Main menu > Settings > Aggregates > Modulating output A…D
Operating line Range Factory setting
Inversion No, Yes No
Meaning:
 Non: 0...100% Load = 0...100% output
 Yes: 0...100% Load = 100...0% output
This means for the sequences:
 No: hhh _ cc: \\\ _ //
 Yes: hhh _ cc: /// _ \\
10.3.3 Limitations
The modulating output (Y) can be limited at the top and at the bottom.
Main menu > Commissioning > Settings > .... or
Main menu > Settings > Aggregates > Modulating output A…D
Operating line Range Factory setting
Positioning signal min 0% ... Positioning signal max 0%
Positioning signal max Positioning signal min... 100% 100%
0...100% output corresponds to
"Positioning signal minimum" (Ymin) ... "Positioning signal maximum" (Ymax).

Qs = Load demand from the sequence controller
The output can thus be parameterized with a DC 5...7.5 V input for controlling a
magnetic valve, for example.
If the modulating output is controlled by more than one internal sequence controller
(see section 15.1.1 "Assign aggregates to sequences"), the larger signal is valid
(max. sele
ction).
