Restrictions
The preprocessing memory is not filled or the filling
process interrupted if the processing section
contains commands that require unbuffered
operation (reference point approach, measuring
functions, ...).
Stop preprocessing
When
STOPRE
is programmed, the following block is
not processed until all previously prepared and stored
blocks have been fully executed. The previous block is
halted with exact stop (as for G9).
Example:
N10 …
N30 MEAW=1 G1 F1000 X100 Y100 Z50
N40 STOPRE
The control system initiates an internal
preprocessing stop while status data of the machine
($A...) are accessed.
Example:
R10 = $AA_IM[X]
;Read actual value of X axis
Note
When a tool offset or spline interpolations are active,
you should not program the STOPRE command as
this will lead to interruption in contiguous block
sequences.
