Moving the machine axes during an interruption

You can move the machine axes during an interruption in the same
way as in the Manual Operation mode.

TNC 426, TNC 430: Caution - Risk of collision!

If you interrupt program run while the working plane is
tilted, you can change from a tilted to a non-tilted
coordinate system, and vice versa, by pressing the 3-D
ON/OFF soft key.

The functions of the axis direction buttons, the electronic
handwheel and the positioning logic for return to
contour are then evaluated by the TNC. When retracting
the tool make sure the correct coordinate system is
active and the angular values of the tilt axes are entered
in the 3-D ROT menu.

Example:
Retracting the spindle after tool breakage
