A sub-program is a normal program that ends with function M99. The same functions can be used inside

the sub-program as used in main programs (e.g. fixed cycles, geometric functions etc.)

To simplify their use, we suggest that sub-programs are given names from O8001 to O8999 (main

programs go from O1 to O8000)

A sub-program is run when it is called by the main program or by another sub-program.

To call up a sub-program, write:

M98 P

OOOO OOOO

Number name of

Repetition sub-program

(max 9999)

When the number of repetitions is omitted the NC assumes a value of 1

Example : sub-program 8003 is to be repeated 6 times consecutively

M98 P68003

Instruction “M99” that closes the sub-program is used to return to the main program (or to the sub-

program) in the block that immediately follows the running of the sub-program.
