Axis stop active
Signal state 0 or edge
change 1 → 0
Confirmation from the NC to the PLC that the axis has been stopped.
System variable: $AA_SNGLAX_STAT = 3 (single axis is interrupted)
Corresponding to ... DB31, ... DBX60.6 (exact stop coarse)
DB31, ... DBX60.7 (exact stop fine)
DB31 ... DBX63.2 (axis stop active)
DB31, ... DBX64.6 (traversing command minus)

DBX76.5
Positioning axis
Edge evaluation: No Signal(s) updated: Cyclic
Signal state 1 or edge
change 0 → 1
Confirmation from the NC to the PLC that the axis is a positioning axis.
DB31, ...
DBD78
F function (feedrate) for positioning axis
Edge evaluation: No Signal(s) updated: when change
Function The axial feedrate programmed for the positioning axis.
The value specified by FC18 for 840D sl is not output.
Signal irrelevant for ... DB31, ... DBX76.5 == 0 (axis is not a positioning axis)
Special cases,
errors, ...
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)
Corresponding to ... DB31, ... DBX76.5 (positioning axis)
MD22240 $MC_AUXFU_F_SYNC_TYPE (output time of F functions)
