Approaching a fixed point in JOG

17.9.1

Function

The machine user can use the "Approaching fixed point in JOG" function to approach axis
positions defined through machine data by actuating the traverse keys of the machine control
panel. The traveling axis comes to a standstill automatically on reaching the defined fixed point.
Note
Approaching a fixed point with G75
The process for approaching defined fixed points can also be activated from the part program
using the G75 command.
For further information on fixed point traversing with G75 see:

(G75)
Applications
Typical applications are, for example:
● Approaching a basic position before starting an NC program.
● Travel towards tool change points, loading points and pallet change points.
Requirements
● The "Approaching fixed point in JOG" 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.
