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.

Y V B
Z W C
The control provides the following functions for machining with the
parallel axes U, V and W:
Soft key Function Meaning Page
PARAXCOMP
Define the control's
behavior when position-
ing parallel axes 555
PARAXMODE
Define the axes the
control is to use for
machining 556
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).
