Leakage Air leakage in actuator/tubing can be compensated by settings.

Undo You can read last 20 changes.

P,I,D and K,Ti,Td parameters

If one of the gains is changed, the corresponding value in the other gain set is changed accordingly.

Spring adjust

The spring adjust function compensates the airflow linearly with the actuator C+ chamber volume (for a constant position

error), so that low volumes get less flow. This is needed for linear single-acting actuators, where a low C+ volume means

that the actuator spring is extended, its force is reduced, and less flow is needed for stable position change.

Fiction
