H1: Manual traversing
17.5 Incremental manual traversing
Risk of collision
If "continuous" mode is selected, several axes can by started by pressing and releasing the
relevant direction key. Any interlocks must be implemented via the PLC!
Note
While an axis is moving, a change of mode from JOG to AUTOMATIC or MDI is not permitted
within the control.
Interface signals
Selection
Incremental traversing in JOG mode must be activated via the PLC interface:
● Machine axes:
– DB31, ... DBX5.0 - 5 (request machine function "INC1" to "INCvar")
● Geometry axes:
– DB21, ... DBX13.0 - 5 (geometry axis 1: Request machine function "INC1" to "INCvar")
– DB21, ... DBX17.0 - 5 (geometry axis 2: Request machine function "INC1" to "INCvar")
– DB21, ... DBX21.0 - 5 (geometry axis 3: Request machine function "INC1" to "INCvar")
● Orientation axes:
– DB21, ... DBX321.0 - 5 (orientation axis 1: Request machine function "INC1" to
– DB21, ... DBX325.0 - 5 (orientation axis 2: Request machine function "INC1" to
– DB21, ... DBX329.0 - 5 (orientation axis 3: Request machine function "INC1" to "INCvar")
