H1: Manual traversing

17.10 Position travel in JOG

17.10 Position travel in JOG
17.10.1

Function

The "Position travel in JOG" function allows the machine operator to specify, via the setting
data, a position in the machine coordinate system, to which the selected machine axis can be
traversed using the traverse keys or the handwheel.
Applications
The function is used for machine tools that are exclusively operated manually, e.g. to approach
drill-holes in precise increments.
Preconditions
● The "Position travel in JOG" function can be activated only in the JOG mode.
The function cannot be activated if the machine function JOG-REPOS or JOG-REF is active
and in JOG in AUTOMATIC.
● The axis to be traversed must be referenced.
● A kinematic transformation may not be active.
● The axis to be traversed may not be a following axis of an active coupling.
Procedure
Procedure for position travel in JOG:
1. Selection of JOG mode
2. Specification of the position to be approached
3. Enabling the "Position travel in JOG" function
4. Traversing of the machine axis with traverse keys or handwheel
Specification of the position to be approached
The position to be approached is entered in the setting data:
SD43320 $SA_JOG_POSITION (JOG position)
Activating the function
The PLC sets the interface signal after the "Position travel in JOG" function has been selected:
DB31, ... DBX13.3 (JOG travel to position)
The NC confirms the activation with the interface signal as soon as the function is effective:
