11.3 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 as standard.
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.

After the TNC is started up, the standard
configuration is always effective.
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.
