2.1.1 Mode group Stop
Function
The following NC/PLC interface signals are used to stop the traversing motions of the axes
or of the axes and spindles in all mode group channels and to interrupt part program
execution:
• DB11, ... DBX0.5 (mode group stop)
• DB11, ... DBX0.6 (mode group stop axes plus spindles)
2.1.2 Mode group RESET
Function
A mode group Reset is requested via a mode group-specific NC/PLC interface signal:
DB11, ... DBX0.7 = 1 (mode group reset)
Sequence in the mode group channels
• Part program preparation (preprocessing) is stopped.
• All axes and spindles are decelerated to zero speed according to their acceleration
curves without contour violation.
• Any auxiliary functions not yet output to the PLC are no longer output.
• The preprocessing pointers are set to the interruption point, and the block pointers are set
to the beginning of the appropriate part programs.
• All initial settings, e.g., G function initial setting, are set to the parameterized values.
• All alarms with "Channel reset" criterion are canceled.
Completion of mode group Reset
Once all mode group channels are in Reset state, mode group Reset is completed as
follows:
• All alarms with "Mode group reset" criterion are canceled.
• The NC/PLC interface indicates completion of the mode group Reset and the mode
group's readiness to operate:
DB11, ... DBX6.7 = 1 (all channels in Reset state)
DB11, ... DBX6.3 = 1 (mode group ready)
