Internal Preprocessing Stop - Siemens Sinumerik 840D sl Programming Manual

Supplementary commands

15.8 Internal preprocessing stop

Application
For example, for relief cutting.
Syntax
G4 F.../S<n>=...
Note
G4 must be programmed in a separate NC block.
Meaning
G4:
F...:
S<n>=...:
Note
Addresses F and S are only used for time parameters in the G4 block. The feedrate F... and
the spindle speed S... programmed upstream of the G4 block are retained.
Example
Program code
N10 G1 F200 Z-5 S300 M3
N20 G4 F3
N30 X40 Y10
N40 G4 S30
N50 X...
15.8 Internal preprocessing stop
Function
The control generates an internal preprocessing stop on access to machine status data ($A...).
The following block is not executed until all preprocessed and saved blocks have been
executed in full. The previous block is stopped in exact stop (as G9).

Activate dwell time
The dwell time is programmed in seconds at address F.
The dwell time is programmed in spindle revolutions at address S.
The numeric extension indicates the number of the spindle to which the dwell
<n>:
time is to be applied. In the absence of a numeric extension (S...) the dwell
time will be applied to the master spindle.
Comment
;Feed F; spindle speed S
; Dwell time: 3 s
; Dwelling 30 revolutions of the spindle (at S=300
rpm and 100% speed override, corresponds to: t = 0.1
min).
; The feedrate and spindle speed programmed in N10
continue to apply.
