Paradox The Limit slider sets the maximum speed of translation that affects physics. Limit is actually a very useful feature because it can be used to restrict how far a bone can move as a result of a physics constraint.
The default value is 5000, which in most cases is high enough that it effectively places almost no restriction on the movement. However, if you try setting it to a smaller value such as 100 or 500, as shown in the video below, you can see that the movement quickly reaches the limit and becomes restricted:
As shown in the video, the Limit value can also be changed in Animate mode. When the movement actually reaches the limit and is being restricted, the Limit label is highlighted, making it easy to see that this setting is currently affecting the movement.
Limit is especially useful when, for example, the amount of bone movement looks appropriate in one animation, but after creating another animation, you find that the bone moves too far and causes the rig to break down. In cases like this, adjusting Limit allows you to keep the movement within a suitable range.
