Response Of The Hirth Axes In Particular Situations - Siemens SINUMERIK 840D sl Function Manual

T1: Indexing axes
16.5 Equidistant index intervals
Activation
● The rotary axis can only approach indexing positions in all modes and operating states.
● In JOG mode, the axis can be traversed under JOG control or incrementally.
● Jogging with the handwheel is not possible.
● Only "coded positions" can be approached in AUTO, MDA or via ASUBs.
● The PLC can only move the axis to indexing positions.

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.
