Detailed Description
2.1 Mode group
Example configuration:
MD10010 $MN_ASSIGN_CHAN_TO_MODE_GROUP[0] = 1
MD10010 $MN_ASSIGN_CHAN_TO_MODE_GROUP[1] = 2
...
MD10010 $MN_ASSIGN_CHAN_TO_MODE_GROUP[3] = 0 ; gap
...
MD10010 $MN_ASSIGN_CHAN_TO_MODE_GROUP[8] = 1
MD10010 $MN_ASSIGN_CHAN_TO_MODE_GROUP[9] = 2
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
• 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
• All initial settings, e.g., G function initial setting, are set to the parameterized values.
• All alarms with "Channel reset" criterion are canceled.
