Introduction

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 table. The traveling axis comes to a standstill automatically on reaching the defined
fixed point.

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 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.
