How I can add to a gear contraint to my simscape multibody model in order to this works only in a determinated instant time?

My problem is that I have a mechanism in simscape/simulink that in a time instant in the simulation appears a new degree of freedom. I would like to know how to restrict that degree of freedom by introducing a gear that only operated at that time instant (temporally constraint) and not in the rest of the simulation since the mechanism is over-constraint and does not work if i add the constraint from the beginning of simulation. The contraint necessary is a gear-constraint.

You can enable/disable degrees of freedom by activating/deactivating Joint blocks. Set the "Mode" parameter to "Provided by Input" to enable a joint at a specific time. You have to make sure that the system is valid when the joint is engaged/disengaged. While this cannot be applied to the Gear Constraint block, you can apply it to joints that connect to the frames associated with the Gear constraint.
If you have a drawing of your system, that would help us understand what you are trying to do.
