Limit stops

Functionality
Limit stops are used to stop the axes in a specific position.
If an axis stops in the limit stop position, it cannot be moved again until the triggering limit stop is reset.
By setting the limit stops, in the MM+ operating area, it is possible to turn simple shoulders (including tapers) without the
need for any further cycle parameterization.
Supplementary conditions
● The limit stop position is always an absolute dimension, which in turn always corresponds to the position in the absolute
actual value display on the MM+ interface. A relative limit stop position is not possible.
● A limit stop position can be entered/accepted only when the axes are stationary; otherwise, an error message appears.

9. Press this softkey.
The modified tool offset for the selected tool is applied in the X axis. Provided that the
"scratch position" in the X axis has not been moved, the measured diameter is now dis-
played as the actual position in the position display of the tool measurement screen.
10. Press this softkey.
The screen for measuring the Z axis appears.
The Z axis can be measured in the same way as the X axis.
When measuring the tool in the Z axis, you may define a distance between the workpiece
and the turning tool tip in input field "a1" to avoid surface damage on the workpiece.
