Function Expression for Force based on Joint Speed in Ansys Motion,

I am using Ansys Workbench Motion and need to define a force that dynamically updates based on a joint's rotational speed during the solution (e.g., the force increases as the speed increases).
Could you please advise on:
What is the exact Function Expression syntax to extract a joint's rotational speed in a specific direction (e.g., Z-axis)?
How can I integrate this speed variable into a Force expression correctly?
Any simple syntax examples would be highly appreciated.
