Cancel Preprocessing Stop (Stopreof) - Siemens SINUMERIK 840D sl Programming Manual

In path control mode, an exact stop is always triggered at the beginning of the block with
RDISABLE in synchronized actions, regardless of whether RDISABLE is active or not.
Example
Start the program in interpolation cycles dependent on external inputs.

Cancel preprocessing stop (STOPREOF)

Function
In the case of an explicitly programmed preprocessing stop STOPRE or a preprocessing
stop implicitly activated by an active synchronized action, STOPREOF cancels the
preprocessing stop after the next machining block as soon as the condition is fulfilled.
Note
STOPREOF must be programmed with the keyword WHEN and non-modally (without
ID number).
Example
Fast program branch at end of block.
WHEN $AC_DTEB<5 DO STOPREOF
G01 X100
IF $A_INA[7]>500 GOTOF MARKE1=X100

;If the voltage 7V is not reached at
;input 2, the program is stopped
;(1000= 1V).
;When the condition is fulfilled,
;the read-in disable is active at the
;end of N10
;Cancel the preprocess stop when distance to
;block end is less than 5mm.
;The preprocessing stop is canceled after
;execution of the linear interpolation.
;If the voltage 5V is exceeded at input 7,
;jump to label 1.
