8.5.4 Optimizing controllers
The control response can be optimized by entering known controller parameters
manually or automatically by means of "self-optimization". During self-optimiza-
tion, the individual controller determines the mathematical parameters for a pro-
cess. The controller changes the output level (step change) and evaluates the
response of the actual value in the process (step response). Following success-
ful self-optimization, the controller parameters determined in this way are adopt-
ed in the "Parameterization" function
⇨ Chapter 9.2 "Parameter Sets (Controller parameter)", page 128
WARNING!
During self-optimization, the controller outputs assume unpredictable values!
Before a self-optimization starts, it must be ensured that greater deviations be-
tween the actual value and the set setpoint value do not cause property damage
or physical injury.

Changing the setpoint values during self-optimization is not possible.
