If you use locked tools, the control displays a warning in the
Programming operating mode.
The M94 miscellaneous function is effective for all rotary axes
that are not limited by software limit switches or traverse limits.
The TRANS DATUM AXIS NC syntax can also be used within a
contour in the SL cycle.
Holes and threads are shown in light blue in the programming
graphics.
The sort order and the column widths are retained in the tool
selection window when the control is switched off.
If a file to be deleted does not exist, FILE DELETE no longer
generates an error message.
If a subprogram called with CALL PGM ends with M2 or M30,
the control issues a warning. The control automatically clears
the warning as soon as you select another NC program.
The time needed to paste a large amount of data into an
NC program was considerably reduced.
When you double-click a selection field of the table editor with
the mouse or press the ENT key, a pop-up window opens.
The machine tool builder configures whether the control will
take the axis angle into account or set it to 0 for the axes
specified in M138.
LN blocks are evaluated with a high accuracy, regardless of
option 23.
The SYSSTR function can be used to read the path of pallet
programs.
If you use locked tools, the control displays a warning in the
Test Run operating mode, see "Test run", Page 249
The control provides a positioning logic for returning to the
contour, see "Returning to the contour", Page 275
The positioning logic for returning to the contour with a
replacement tool has changed, see "Tool change", Page 138
If the control finds a stored interruption point on restart, you can
resume the machining operation from that point, see "Any entry
into the NC program: Block scan", Page 269
Axes that are not active in the current kinematic model can
also be referenced in a tilted working plane, see "Crossing the
reference point in a tilted working plane", Page 161
The tool is shown in red in the graphics while it is in contact
with the workpiece, and blue during air cuts, see "Tool",
Page 236
The positions of the sectional planes are no longer reset when
a program or a new blank form is selected, see "Shifting the
sectional plane", Page 241
Spindle speeds can be entered with decimal places also in
the Manual operation mode. The control displays the decimal
places when the spindle speed is < 1000, see "Entering values",
