Detailed Description
2.12 Block search
Auxiliary Function Output to PLC (H2)
2-30 Function Manual, 08/2005 Edition, 6FC5397-0BP10-0BA0
Behavior regarding: M19 (position spindle)
After block search, the last spindle positioning programmed with M19 is always performed,
even if other spindle-specific auxiliary functions are programmed between the part program
block with M19 and the target block. Setting the necessary spindle enables must therefore
be derived from the interface signals of the traverse commands in the PLC user program:
DB31, ... DBX64.6/64.7 (traverse command minus/plus)
In this case, the spindle-specific auxiliary functions M3, M4, M5 are not suitable because
they might not be output to the PLC until after spindle positioning.

2.12.2 Output suppression of spindle-specific auxiliary functions
Function
For example, with 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.
This requires suppression of automatic output of the spindle-specific auxiliary functions after
block search. Output can then be performed manually later by overstoring or by an ASUB.
Parameterization
Suppression of automatic output of the spindle-specific auxiliary functions after block search
is performed via:
MD11450 $MN_SEARCH_RUN_MODE, bit 2
Bit 2 = 0
Output of the spindle-specific auxiliary functions is performed in the action blocks
Bit 2 = 1
Output of the auxiliary functions is suppressed in the action blocks
