2.6.6 Special features in the part-program target block
2.6.6.1 STOPRE in the part-program target block
STOPRE block
The STOPRE block receives all modal settings from the preceding block and can, therefore,
apply conditions in advance in relation to the following actions:
• Synchronize program line currently processing with the main run.
• Derive modal settings for SERUPRO in order, for example, to influence this REPOS
motion on approach of SERUPRO.
Example 1:
Position a Z axis by specifying an X axis setpoint.
When block "G1 F100 Z=$AA_IM[X]" is interpreted, the preceding STOPRE block ensures
synchronization with the main run. The correct setpoint of the X axis is thus read via $AA_IM
to move the Z axis to the same position.
Example 2:
Read and correctly calculate external zero offset.
N10 G1 X1000 F100
;
N20 G1 X1000 F500
;
N30 G1 X1000 F1000
;
N40 G1 X1000 F5000
;
N50 SUPA G1 F100 X200
;
ove external zero offset after
200
N60 G0 X1000
;
N70 ...
;
Via an implicit STOPRE before N50, the NCK can read and correctly and correctly compute
the current zero offset.
For a SERUPRO operation on the search target N50 repositioning occurs in the SERUPRO
approach to the implicit STOPRE and the speed is determined from N40 with F5000.
