3.11.2 KP DN – KP value (down)
NOTE
In the case of most actuators, all control parameters can be optimized by using Auto Adjust. Changes should
only be made when auto adjust cannot be executed or control stability cannot be achieved.
The KP value is the gain of the controller. The control speed and stability are influenced by the KP value. With higher KP values, the
control speed increases.
NOTE
The control precision is not affected by the KP value.
To compensate for existing asymmetries in the controlled system, the KP value should be set separately for both positioning directions
(up / down). For most actuators, satisfactory control behavior is achieved with a KP value between 2.0 ... 10.0. Use the KP DN parameter
to adjust the KP value for the downward positioning direction (towards 0 %).
