Detailed description
2.10 M function with implicit preprocessing stop
2.10 M function with implicit preprocessing stop
Function
Triggering a preprocessing stop in conjunction with an auxiliary function can be programmed
via theSTOPRE part program command. Triggering a preprocessing stop in conjunction with
an M function can be programmed explicitly via theSTOPRE part program command.
Always triggering a preprocessing stop in M function programming can be parameterized for
each M function via the following machine data:
MD10713 $MN_M_NO_FCT_STOPRE (M function with feed stop)
Preprocessing stop with M function M88
The user-defined M function M88 is intended to trigger a preprocessing stop.
Parameterization
MD10713 $MN_M_NO_FCT_STOPRE [ 0 ] = 88 (M function with feed stop)
Application
Parts program (extract)
N100 G0 X10 M88
N110 Y=R1
Constraints
If a subroutine called indirectly via an M function in a part program in one of the following
ways, no preprocessing stop is performed:
• MD10715 $MN_M_NO_FCT_CYCLE (M function to be replaced by subroutine)
• M98 (ISO dialect T / ISO dialect M)
44
; Traverse movement and implicit preprocessing stop via M88
; N110 is only interpreted after the traverse motion has been
completed and
; acknowledgement of the M function.
