The Limit Scale Value works as follows;

1. We have a value inside our Value input
2. Using our Limit Min / Limit Max input we can decide what values are coming in of the actor. All values that are lower then Limit Min will be put at Limit Min and all values higher then Limit Max will be put at the numeric value that we entered in Limit Max.
3. Using our Out min / Out max we can now rescale our value that is sent to our output.

For example;

We have a numeric value that goes from 1 till 100, we want to only receive 50 till 100 and rescale that from 0 till 10.

Limit Min; 50

Limit Max; 100

Out Min; 0

Out Max; 10

Our values that we will receive

To answer your question; normally you use Out Min / Out max and reverse those two to get an inverted value.
