Use Case 4
Reset axis/spindle
An axis/spindle is reset to its initial state.
Description of operational sequence:
● PLC requests the NCK to reset motion on the relevant axis with NST:
● NCK detects that the axis/spindle is active and switches it to the stopped state.
● The interrupted sequences are canceled and notified to the PLC as for "Delete distance
● The internal NCK states for the axis/spindle are reset.
● The axial machine data effective on RESET become operative.
● An axial RESET has been performed is reported at the interface:
● NCK ends this operation.
Alternatives
The NCK detects that the relevant axis/spindle:
● is in the state "stopped":
● is in the state "StopByAlarm":
● is not active:
Marginal conditions
The PLC must already have accepted control of the axis/spindle. NST DB31, ... DBX28.1
(AXRESET) is otherwise ignored.

Note
In the case of a channel reset, no axial machine data becomes operative for an axis
controlled by the PLC.
DB31, ... DBX63.0 ("AXRESET DONE") == 1
DB31, ... DBX63.2 ("Axis stop active") == 0
and
System variable $AA_SNGLAX_STAT == 1 single axis in RESET active.
