Boundary condition:
● The axis/spindle must be currently controlled by the PLC.
● The signal is ignored for following error situations:
– The axis/spindle is not controlled by the PLC.
– The axis/spindle is not in the stopped state.
– The axis/spindle must not resume traversing because an alarm is present.
DB31, ... DBX28.1 (reset)
DB31, ... DBX60.6 (exact stop coarse)
DB31, ... DBX60.7 (exact stop fine)
DB31 ... DBX63.2 (axis stop active)

System variable: $AA_SNGLAX_STAT
OPI variables: aaSnglAxStat
Axial alarm
Signal(s) updated: Cyclic
Effects:
● The axis/spindle is stopped by the NCK via a braking ramp.
● OPI variables: aaSnglAxStat = 5 (alarm)
● $AA_SNGLAX_STAT = 5 (axial alarm is present)
● DB31 ... DBX61.1 = 1 (axial alarm)
Reset executed
Signal(s) updated: Cyclic
The following state is present after the reset:
● The machine data of the axis/spindle is reloaded
● DB31 ... DBX63.0 == 1 (reset executed)
● DB31 ... DBX63.2 == 0 (axis stop active)
● System variable $AA_SNGLAX_STAT == 1
● OPI variables: aaSnglAxStat == 1
