Configure the controller algorithm CONT_C
General
To determine which components of the control algorithm are activated, proceed as follows:
1. Select an entry from the "Controller structure" list.
You can only specify required parameters for the selected controller structure.
Proportional action
1. If the controller structure contains a proportional action, enter the "proportional gain".
Integral action
1. If the controller structure contains an integral action, enter the integral action time.
2. To give the integral action an initialization value, select the check box "Initialize integral
action" and enter the initialization value.
3. In order to permanently set the integral action to this initialization value, select the
"Integral action hold" check box.
Derivative action
1. If the controller structure contains a derivative action, enter the derivative action time, the
derivative action weighting and the delay time.
