9.8 Block search Type 5 (SERUPRO)
Reaching simulated target point for LEAD with JOG
At the time of "Search target found", the coupling is already active, especially for the JOG
motions. If the target point is not reached, SERUPRO approach can be used to traverse the
following axis with active coupling and an overlaid motion to the target point.
Note
For further information on the repositioning of axis couplings, see Section "Repositioning to
the contour (REPOS) (Page 497)".
Master-slave
A system ASUB can be started automatically after the block search is finished. In this
subprogram, the user can control the coupling state and the associated axis positions
subsequently. The required information is provided via the following system variables:
System variable
$P_SEARCH_MASLD[<slave axis>]
$AA_MASL_STAT[<slave axis>]
$P_SEARCH_MASLC[<slave axis>]
The system variables are deleted when the coupling is switched on with MASLON.
Note
The coupled axes must be in the same channel when the block search is executed.
