When a suggested edit is approved, the user who suggested it gets +2 reputation. The regular daily reputation cap applies, and the total cap is 1,000. Like any other reputation, the +2 is deleted if the edited post is ever deleted.
So since your rep is below 2000, you get +2 for each suggested edit which is approved.
Adding some very useful and obscure info verbatim from @damryfbfnetsi in the comments, there's one exception to the rule that you lose rep if you suggest an approved edit to a later-deleted post: if your suggested edit was to a tag wiki, and the tag is later burninated/manually removed, you get to keep the reputation (it will show up as editing an "orphan wiki")
