Response of the Hirth axes in particular situations

STOP/RESET
When NC-STOP and RESET are performed during a traversing movement, the next indexing
position is approached.
EMERGENCY STOP
After an EMERGENCY STOP, the PLC or the operator must move the indexing axis back to an
indexing position in JOG mode before the longitudinal axis can be moved in/down.
Override = 0 or signal "axis stopped"
If the axis has already moved away from the previous indexing position when these events
occur, the control moves the axis to the next possible indexing position before the response
is initiated.
Deletion of distance-to-go
After traversing to the next possible indexing position, the movement is aborted at this
position.
Command axes
If MOV = 0 is specified for a moving command axis, the axis continues traversing to the next
possible indexing position.

Works on indexing axes with and without Hirth tooth system.
Same function for both: approaches the next position.
Axis stops immediately.
Axis traverses to next position.
