General Purpose M Codes - Siemens Sinumerik 802D sl Programming Manual

Movement Control Commands
3.7 Miscellaneous function (M function)
Limitations
Only one M function replacement (or one subprogram call) can be performed on
each part program line. Conflicts with other subprogram calls are reported with
alarm 12722. No more M functions will be replaced in the subprogram replaced.
Generally, the same limitations apply as with G65.
Configuring example
Call the subprogram M101_MAKRO by the M function M101
$MN_EXTERN_M_NO_MAC_CYCLE[0] = 101
$MN_EXTERN_M_NO_MAC_CYCLE_NAME[0] = "M101_MAKRO"
Call of the subprogram M6_MAKRO by the M function M6.$MN_EX-
TERN_M_NO_MAC_CYCLE[1] = 6
$MN_EXTERN_M_NO_MAC_CYCLE_NAME[1] = "M6_MAKRO"

General purpose M codes

Other general M codes
The functions of the M codes other than the specific M codes are determined by
the machine tool builder. The representative use of several general M codes is
given below. For details, refer to the instruction manuals published by the machine
tool builder. If an M code is specified with axis move commands in the same block,
whether the M code is executed with the axis move commands simultaneously or it
is executed after the completion of the axis move commands is determined by the
machine tool builder. For details, refer to the instruction manuals published by the
machine tool builder.
