P2: Positioning axes
10.3 Motion behavior and interpolation functions
Use case 3: Continue axis/spindle
Traversing motion interrupted after Use case 2 "Stop axis" should be continued.
Description of the sequence:
● PLC → NCK: Continue axis
● NCK: Checks whether for the axis/spindle an axial alarm with delete criterion
● NCK: Checks whether axis motion can be resumed? If yes, then the axis/spindle makes
● NCK confirms the execution:
Result: Traversing motion of the axis/spindle is continued.
Boundary conditions
In the following cases, the request to continue is ignored:
● The axis/spindle is not controlled by the PLC.
● The axis/spindle is not in the stopped state.
● An alarm is pending for the axis/spindle.
Use case 4: Reset axis/spindle (reset)
Description of the sequence:
● PLC → NCK: Reset request for this axis/spindle
● NCK: Transitions the axis/spindle into the "stopped" state.
● NCK: Interrupts the stopped sequences and signals to the PLC the interruption -
● NCK: The internal states for the axis/spindle are reset.
● NCK: The axial machine data effective at reset becomes active.
Note
In contrast to a reset due to DB31, ... DBX28.1 = 1 (reset), in conjunction with a channel
reset, no axial machine data is active for axes controlled from the PLC.

"CANCELCLEAR" or "NCSTARTCLEAR" is present? If yes, then this is deleted.
the transition into the "active" state.
– DB31, ... DBX60.6 = 0 (exact stop coarse)
– DB31, ... DBX60.7 = 0 (exact stop fine)
– DB31, ... DBX63.2 = 0 (axis stop active)
– DB31, ... DBX64.6 / 7 = 1 (traversing command minus/plus)
– Axis state active with system variable $AA_SNGLAX_STAT == 4.
DB31, ... DBX28.1 = 1 (reset)
essentially the same as for "Delete distance-to-go".
