12.7 Working with the parallel axes
U, V and W
Overview
Refer to your machine manual.
Your machine must be configured by the machine
manufacturer if you want to use parallel-axis functions.
Depending on the configuration, the PARAXCOMP
function may be activated by default.
The axes U, V and W are secondary axes parallel to the principal
axes X, Y and Z, respectively. Principal axes and parallel axes are
permanently assigned to each other.

The control provides the following functions for machining with the
parallel axes U, V and W:

PARAXCOMP
PARAXMODE
After the control has been started up, the standard
configuration is effective by default.
You must deactivate the parallel-axis functions before
switching the machine kinematics.
You can deactivate the programming of parallel axes
with the machine parameter noParaxMode (no. 105413).
