Cancel Preprocessing Stop (Stopreof); Delete Distance-To-Go (Deldtg) - Siemens SINUMERIK 840D sl Function Manual

Detailed description
3.7 Actions in synchronized actions
does not act on block N115 – but instead on the internal REPOSA block. As a consequence, to
start, positioning axis X is traversed to its programmed position and then in block N115, the Y
axis to its programmed position.
An explicit release of path axis X before traversing as positioning axis (synchronized action in
N105) with RELEASE(X) avoids the REORG operation, and the X and Y axes traverse together
in block N115.
Program code
N100 G0 G60 X300 Y300
N101 RELEASE(X)
N105 WHEN TRUE DO POS[X]=20 FA[X]=20000

Cancel preprocessing stop (STOPREOF)

With the STOPREOF command, an existing preprocessing stop can be cancelled from a
synchronized action.
Note
The STOPREOF command can only be programmed in non-modal synchronized actions
(without specification of ID or IDS) and only in conjunction with the scanning frequency WHEN.
Example
● N10: Non-modal synchronized action.
If the path distance-to-go $AC_DTEB is less than 5 mm, the existing preprocessing stop
due to the reading of the analog input $A_INA is cancelled.
● N20: Traversing block whose path distance-to-go is evaluated via $AC_DTEB.
● N30: Branch that triggers the preprocessing stop due to the reading of $A_INA.
Due to the synchronized action, input $A_INA is not evaluated at the end of the N20 block, but
already 5 mm before the end of the block. If the voltage is then greater than 5 V at input $A_INA,
there is a branch to "MARKE_1".
Program code
N10 WHEN $AC_DTEB < 5 DO STOPREOF
N20 G01 X100
N30 IF $A_INA[7] > 5000 GOTOF MARKE_1

Delete distance-to-go (DELDTG)

The path distance-to-go can be deleted with the DELDTG command and axial distances-to-go
can be deleted with the DELDTG (...) function in synchronized actions.
