Positioning Non-Controlled Axes
The machine manufacturer determines which axes will
be controlled automatically by the TNC and which will
be controlled via mechanical handwheels.
The machine manufacturer sets two operating modes for the display
of non-controlled axes:
• The position display shows the actual position of the machine
slide
• The position display shows the distance-to-go to the
programmed nominal position
You will recognize an axis in distance-to-go mode by the D symbol
to the upper right of the axis designation.
If your TNC displays distance-to-go to nominal position, you can
program and execute a manually traversed axis simply by moving
the machine slide to display value zero.
The distance-to-go mode functions as follows during Program Run:
ä Enter the program including the manual positionings.
ä Start program run.
ä The TNC will stop program run at manual positioning blocks.
ä Position the machine slide manually by traversing to zero.
ä Start program run once again.
