Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

Model of constant force which changes sign with direction of movement.

Please note:
Positive force accelerates in both directions of movement.
Negative force brakes in both directions of movement.

Around zero speed regularization avoids numerical problems.
