8.13.5 Output suppression of spindle-specific auxiliary functions
Function
In certain situations, such as a tool change, it may be necessary not to output the spindle-specific auxiliary
functions collected during the block search in action blocks, but to delay output, for example, until after a tool
change. The automatic output of the spindle-specific auxiliary functions after a block search may be suppressed
for this purpose. Output can then be performed manually later by overstoring or by an ASUB.
Parameterization
Suppression of the automatic output of the spindle-specific auxiliary functions after a block search is set via
machine data:
MD11450 $MN_SEARCH_RUN_MODE (behavior after a block search)
System variables
The spindle-specific auxiliary functions are always stored in the following system variables during block
searches, irrespective of the parameter assignment described above:
For later output of the spindle-specific auxiliary functions, the system variables can be read in an AS, for
example, and output after the action blocks are output:
Bit Value Meaning
2 0 The output of the spindle-specific auxiliary functions is performed in the action blocks.
1 Output of the auxiliary functions is suppressed in the action blocks.
