F7MAXN sets a limit on the number of overflow, underflow and divide check messages that will be printed. After the limit is exceeded, the faults are still processed, but no message is printed. If F7MAXN is not called the default limit is 3 in TSS and 10 in batch.
Whether or not F7MAXN is called, if any overflow or divide checks occur, a summary message with the number faults will be printed.
