04.97 Basic Definitions
2.3.7 M-functions
Via M-functions the user has the possibility to define the control of his machine functions when
programming traversing programs.
Programming:
N10 G90 G43 G01 X100.000 F4000.00 M1=10 M2=11 M3=13 D1
M-functions are defined by the address character M1=, M2=, M3= and a figure between 0
and 254. Up to three M-functions can be programmed per traversing block. The user-assigned
M-functions may be programmed as desired. The M-functions with special functions must be
programmed in the M1 group (Exeption: M97 and M98).
