Bit6: Output during motion
The auxiliary function is output during the traverse movements programmed in the part
program block (path and/or block-related positioning axis movements).
Bit7: Output at block end
The auxiliary function is output after completion of the traverse movements programmed in
the part program block (path and/or block-related positioning axis movements).
Bit8: No output after a block search
The collected auxiliary function is not output after a block search.
Note
In the case of auxiliary functions for which no output behavior has been defined, the
following default output behavior is active:
•
•
