Plus and minus traversing keys for geometry axis (1, 2, 3)
Edge evaluation: No Signal(s) updated: Cyclically
Signal state 1 The selected geometry axis can be traversed in both directions in JOG mode with the traversing
keys plus and minus.
Depending on the active machine function as well as the setting "JOG or Continuous mode":
SD41050 $SN_JOG_CONT_MODE_LEVELTRIGGRD (JOG/Cont. mode continuous with JOG)
and
MD11300 $MN_JOG_INC_MODE_LEVELTRIGGRD (INC and REF in JOG mode)
different reactions are triggered on a signal change.
1. Continuous traversing with JOG mode
The geometry axis traverses in the direction concerned as long as the interface signal
is set to 1 (and as long as the axis position has not reached an activated limitation).
2. Continuous traversing with Continuous mode
On the first edge change 0 →1, the geometry axis starts to traverse in the relevant direction.
This traversing movement still continues when the edge changes from 1 → 0. Any new edge
change 0 →1 (same traversing direction!) stops the traversing movement.
3. Incremental traversing with JOG mode
With signal 1 the geometry axis starts to traverse at the set increment. If the signal changes to
the 0 state before the increment is traversed, the traversing movement is interrupted. When the
signal state changes to 1 again, the movement is continued. The geometry axis can be stopped
and started several times as described above until it has traversed the complete increment.
4. Incremental traversing with Continuous mode
On the first edge change 0 → 1 the geometry axis starts to traverse at the set increment. If
another edge change 0 → 1 is performed with the same traverse signal before the geometry
axis has traversed the increment, the traversing movement will be cancelled. The increment
traversing will then not be completed.
Note
• If both traversing signals (plus and minus) are set at the same time there is no traversing or the
current traversing is aborted.
• In contrast to machine axes, for geometry axes, only one geometry axis can be traversed at
any one time using the traversing keys.
• Traversing by means of the traversing keys can be locked via DBX12.4 = 1 ff. (traversing key
disable).

The geometry axis cannot be traversed in JOG mode:
• If it is already being traversed via the axial PLC interface (as a machine axis).
• If another geometry axis is already being traversed with the traversing keys.
Alarm 20062 "Axis already active" is output.
