Incremental manual travel

Function

With incremental traversing, the operator specifies the number of increments to be traversed
by the axis via the machine control panel.
In addition to five fixed increment sizes (default setting: INC1, INC10, INC100, INC1000 and
INC10000), a variable increment size (INCvar) that can be set via the setting data is also
available.
Incremental travel in jogging mode
If the traversing key for the required direction (e.g. +) is pressed, the axis begins to traverse
the increment that has been set. If the traversing key is released before the increment has
been fully traversed, the movement is interrupted and the axis stops. If the same traversing
key is pressed again, the axis traverses the remaining distance until it is zero. Up to this point,
the movement can still be interrupted by releasing the traversing key.
Pressing the traversing key for the opposite direction does not have any effect, unless the
increment has been fully traversed or the movement has been aborted.
Cancel traversing movement
If the increment should not travel to the end, the traversing movement can be interrupted as
follows:
● RESET
● DB31, ... DBX2.2 (delete distance-to-go)
Incremental travel in continuous mode
The axis traverses the entire set increment when the traversing key is pressed (first rising
edge). If the same traversing key is pressed again (second rising edge) before the axis has
finished traversing the increment, the traversing movement is aborted, i.e. not completed.
Interrupt traversing movement
Behavior as for continuous traversing (see "Continuous manual travel (Page 157)").
Cancel traversing movement
The traversing movement can be stopped and aborted by means of the following operations
or monitoring functions:
● Pressing the same traversing key again
● Pressing the traversing key for the opposite direction
● RESET
● DB31, ... DBX2.2 (delete distance-to-go)
