Slow strong prismatic joint

Hi. I'm having some problems modelling a slow and strong prismatic joint (real world screw joint). The problem seems to be that `` is not being considered. My joint looks like: 1 And I'm controlling the joint through a Gazebo plugin that uses `JointController` and a position PID with `SetPositionTarget`. Currently I'm using `10000.0 0 0 ` for parameters because the distance is quite small. When I set a position target for this joint it moves a lot faster than the `` tag indicates, and it seems to be the case however I tune the PID. The rest of the robot should have the correct masses so I don't think that is the problem.
