Checking the axis positions

After switch-on the TNC checks whether the position of an axis

matches the position directly after switch-off. If it differs, the TNC

marks this axis in the position display with a warning triangle after the

position value. Axes that are marked with a warning triangle can no

longer be moved while the door is opened.
In such cases you must approach a test position for the axes in

question. Proceed as follows:

Select the Manual Operation mode

Scroll through the soft-key row until you see a row listing all axes

that you have to move to the test position

Via soft key, select an axis that you want to move to the test position

Approach with NC start

When the test position has been reached, the TNC asks whether the

position was approached correctly: Confirm with the YES soft key if

the TNC approached the test position correctly, and with NO if the

position was not approached correctly

If you confirmed with YES, you must confirm the correctness of the

test position again with the permissive button on the machine

operating panel

Repeat this procedure for all axes that you want to move to the test

position

This function must be adapted to the TNC by your

machine manufacturer. The machine manual provides

further information.

Danger of collision!

Approach the test positions successively in such a way

that no collision between tool and the workpiece or the

clamping devices can occur. If necessary, pre-position the

axes manually.

The location of the test position is specified by your

machine tool builder. The machine manual provides

further information.
