Modified functions 77185x-05
If you use locked tools, the control displays a warning in
the Programming and Test Run operating modes, see
"Programming graphics", page 186, see "Test run",
page 599
The control offers a positioning logic for returning to the contour,
see "Returning to the contour", page 618
The positioning logic for returning to the contour with a
replacement tool has changed, see "Tool change", page 224
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 515
Holes and threads are shown in light blue in the programming
graphics, see "Programming graphics", page 186
The tool is shown in red in the graphics while it is in contact
with the workpiece, and blue during air cuts, see "Tool display",
page 594
The positions of the sectional planes are no longer reset when
a program or a new blank form is selected, see "Projection in
three planes", page 592
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",
page 529
The sort order and the column widths in the tool selection
window are retained when the control is switched off, see
"Calling the tool data", page 222
If a subprogram called with %: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, see
"Programming notes", page 324
The control displays an error message in the header until it is
cleared or replaced by a higher-priority error, see "Display of
errors", page 190
The time needed to paste a large amount of data into an
NC program was considerably reduced.
To connect a USB stick you no longer have to press a soft
key, see "Connecting and removing USB storage devices",
page 157
The speed of setting the jog increment, spindle speed and feed
rate was adjusted for electronic handwheels.
The icons of basic rotation, 3-D basic rotation and tilted working
plane were modified to make them easier to distinguish, see
"General status display", page 84
The control automatically recognizes whether a table is to be
imported or the table format is to be adapted, see "Importing
tool tables", page 216
When you place the cursor in an input field of the tool
management, the entire input field is highlighted.
When you double-click a selection field of the table editor with
the mouse or press the ENT key, a pop-up window opens.
When configuration subfiles are modified, the control no longer
aborts the test run, but only displays a warning.
