In the Max Passes box of the Constraint Cuts box:

you can control the number of iterative passes the integer pre-solver makes through a model to determine appropriate constraint cuts to append to the formulation. In general, the benefits of each successive pass decline. At some point, additional passes will only add to the total solution time. Thus, LINGO imposes a limit on the maximum number of passes.

The default limit is 100 passes at the root node of the branch-and-bound tree, and 2 passes at all subsequent nodes.
