  • Are usually a series of commands that are repeated several times in a program.
  • Are written in a separate program, instead of repeating the commands many times in the main program.
  • Are called in the main program with an M97 or M98 and a P code.
  • Can include an L for repeat count. The subprogram call repeats L times before the main program continues with the next block.

When you useM97:

  • The P code (nnnnn) is the same as the block number (Nnnnnn) of the local subprogram.
  • The subprogram must be within the main program

When you use M98:

  • The P code (nnnnn) is the same as the program number (Onnnnn) of the subprogram.
  • The subprogram must reside in the active directory, or in a location specified in Settings 251/252. Refer to Setting 252 for more information on subprogram search locations.

Canned Cycles are the most common use of subprograms. For example, you might put the X and Y locations of a series of holes in a separate program. Then you can call that program as a subprogram with a canned cycle. Instead of writing the locations once for each tool, you write the locations only once for any number of tools.
