Whatever you wish. If you want to make as many steps as possible, then

set it to the number of vertices. (As suggested in the documentation.)
You can check the modularity score of the communities. If I remember

well, this method stops splitting the communities if the modularity
values cannot be increased by any split.
Which is fine, as long as the function works. You only need to change

it if you have special graphs, e.g. very sparse ones with long cycles.
