Edge evaluation: No
Signal state 1 or This interface signal defines how many increments the machine axis traverses when the traverse
edge change 0 → 1 key is pressed or the handwheel is turned one detent position. JOG mode must be active for this
(exception: with DRF).
The increment size associated with the individual interface signals is defined as follows:
•
•
As soon as the selected machine function becomes active, this is signaled to the PLC interface:
DB31, ... DBB65 (active machine function INC1; ... )
If several machine function signals (INC1, INC... or DB31, ... DBX5.6) are selected at the interface
simultaneously, no machine function is activated by the control.
Signal state 0 or The machine function in question is not selected.
edge change 1 → 0
If an axis is currently traversing an increment, this movement is also aborted if this machine
function is deselected or switched over.

DBX5.6 Continuous machine function
Edge evaluation: No
Signal state 1 or The machine function:
edge change 0 → 1 DB31, ... DBX5.6 (continuous jogging)
is selected.
The associated machine axis can be traversed with the traverse keys plus and minus in JOG
mode.
Signal state 0 or The machine function:
edge change 1 → 0 DB31, ... DBX5.6 (continuous jogging)
is not selected.
