The overcurrent protection is always working if available. This will trigger if the wheel is stuck. One issue is, if it does get stopped, then it will allow a higher current in the opposite direction to try to "unstuck" itself but this is usually ok even if the wheel is stuck.
Depending on the controller it may or may not have:
1) overcurrent - works for end of travel or blocked wheel
2) end stop switches - switch in either direction prevents further travel
3) rudder feedback - user sets rudder range and movement doesn't go past this
My controllers support all 3, but I do not provide hardware for #2 or #3 (yet) so they must be wired to the controller if they exist. Several other members have implemented controllers without #1 which I don't recommend, but as long as one of the above is implemented, there is a way to prevent stalling. These controllers obviously won't detect a stuck wheel. Any or all of these can be used at the same time, and the logic individually does not change. For example, having end stop switches will work as backup if the rudder feedback fails. If the end of travel switches fail then overcurrent will be triggered.
