Description
KP Up
1.0 to 400.0
Use this parameter to adjust the KP value for the up
positioning direction (towards 100 %).
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.
To compensate for existing dissymmetries 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 and 10.0.
Note:
The control precision is not affected by the KP value.
KP Down
1.0 to 400.0
Use this parameter to adjust the KP value for the down
positioning direction (towards 0 %).
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.
To compensate for existing dissymmetries 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 and 10.0.
Note:
The control precision is not affected by the KP value.
TV Up
10 to 800 ms
Use this parameter to adjust the KP value for the up
positioning direction (towards 100 %).
The TV value is the derivative time of the controller.
The control speed and stability are affected by the TV
value in such a way that it counteracts the KP value
dynamically. The control speed decreases as the TV
value increases.
To compensate for existing dissymmetries in the
controlled system, the TV value should be configured
separately for both positioning directions (up/down).
