Axis stop active
Confirmation from the NC to the PLC that the axis has been stopped.
System variable: $AA_SNGLAX_STAT = 3 (single axis is interrupted)
DB31, ... DBX60.6 (exact stop coarse)
DB31, ... DBX60.7 (exact stop fine)
DB31 ... DBX63.2 (axis stop active)
DB31, ... DBX64.6 (traversing command minus)
DB31, ... DBX64.7 (traversing command plus)
System variable: $AA_SNGLAX_STAT
Positioning axis
Signal(s) updated: Cyclic
Confirmation from the NC to the PLC that the axis is a positioning axis.
F function (feedrate) for positioning axis
Signal(s) updated: when change
The axial feedrate programmed for the positioning axis.
The value specified by FC18 for 840D sl is not output.
DB31, ... DBX76.5 == 0 (axis is not a positioning axis)
If the positioning axis is traversed with the feedrate from the machine data, the NC does not
output an F function (feed) to the PLC:
MD32060 $MA_POS_AX_VELO (initial setting for positioning axis velocity)
DB31, ... DBX76.5 (positioning axis)
MD22240 $MC_AUXFU_F_SYNC_TYPE (output time of F functions)
Z2: NC/PLC interface signals
