DBX61.1 Axial alarm
Edge evaluation: No Signal(s) updated: Cyclic
Signal state 1 or edge
change 0 → 1
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)
DB31, ...
DBX63.0 Reset executed
Edge evaluation: No Signal(s) updated: Cyclic
Signal state 1 or edge
change 0 → 1
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
Corresponding to ... DB31, … DBX28.1 (reset)
