Manual and Handwheel Travel (H1)
Continuous travel
Abort 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 (second rising edge)
● Pressing the traversing key for the opposite direction
● RESET
● On deselection of the continuous mode
● On reaching the first valid limitation
● In the event of faults
4.2.3 Special features of continuous travel
Indexing axes
When an axis that is declared as an indexing axis is traversed in continuous mode, it always
traverses to indexing positions. For example, the axis traverses on to the next indexing
position in the direction of travel even if the traversing key is released in inching mode.
