H1: Manual traversing
17.4 Continuous manual traversing
Abort traversing movement
The operator can cancel traversing via the operator controls of the machine control panel
(MCP) in the following ways:
● Pressing the same traversing key again
● Pressing the traversing key for the opposite direction
● RESET
● Deselection of the JOG mode by changing the operating mode to AUTOMATIC or MDI
The traversing movement is canceled by the controller:
● If an active traversing range limit is reached (working area limitation, software limit switch,
etc.)
● If an alarm occurs with cancellation of the traversing movements
Interface signals
Selection
Continuous traversing in JOG mode must be activated via the PLC interface:
● Machine axes:
– DB31, ... DBX5.6 (request machine function "Continuous manual traversing")
● Geometry axes:
– DB21, ... DBX13.6 (geometry axis 1: Request machine function "Continuous manual
– DB21, ... DBX17.6 (geometry axis 2: Request machine function "Continuous manual
– DB21, ... DBX21.6 (geometry axis 3: Request machine function "Continuous manual
● Orientation axes:
– DB21, ... DBX321.6 (orientation axis 1: Request machine function "Continuous manual
– DB21, ... DBX325.6 (orientation axis 2: Request machine function "Continuous manual
– DB21, ... DBX329.6 (orientation axis 3: Request machine function "Continuous manual

CAUTION
Traversing range limit inactive
Software limit switches and working-area limitations are only active after referencing of the
axis.
