It is possible to search quickly for a file in file management by
entering the first letter, see "Selecting drives, directories and
files", page 148
File management displays vertical scrollbars and supports
scrolling with the mouse, see "Calling the file manager",
page 147
New machine parameter for recreating M7 and M8, see
"Machine-specific user parameters", page 658
The function STRLEN checks whether a string parameter has
been defined, see "Finding the length of a string parameter",
page 408
The function SYSSTR enables the NC software version to be
read out, see "Reading system data", page 405
The function D38 can now be programmed without a code
number
Undefined Q parameters can now be transferred with the
function D00
For jumps with D09, QS parameters and texts are permitted as
conditions, see "Programming if-then decisions", page 349
Cylindrical workpiece blanks can now also be defined with a
diameter instead of a radius, see "Defining the blank: G30/G31",
page 129
The transitional elements G24 and G25 can now also be
executed between 3-D contours, i.e. with straight line blocks
with three programmed coordinates or a helix
The control now supports spatial arcs, i.e. circles in 3 axes
vertical to the working plane, see "Circular path around circle
center ", page 267
Active kinematics is displayed in the 3D-ROT menu, see
"Activating manual tilting:", page 576
In operating modes Program run, single block and Program
run, full sequence the screen layout PROGRAM + SECTS can be
specified, see "Structuring programs", page 179
In operating modes Program Run Full Sequence, Program Run
Single Block and Positioning w/ Manual Data Input, the font
size can be set to the same size as the Programming operating
mode, see "Machine-specific user parameters", page 658
The functions in the Positioning w/ Manual Data Input mode
were expanded and adapted for improved operation, see
"Positioning with Manual Data Input", page 579
Active kinematics is displayed in the operating mode RETRACT,
see "Retraction after a power interruption", page 610
In the RETRACT operating mode, feed-rate limitation can be
deactivated with the CANCEL THE FEED RATE LIMITATION soft
key, see "Retraction after a power interruption", page 610
In the Test Run operating mode a tool usage file can also be
created without simulation, see "Tool usage test", page 226
In the Test Run operating mode you can hide the rapid traverse
movements with the FMAX PATHS soft key, see "3-D view in the
Test Run operating mode", page 590
In the Test Run operating mode you can reset the solid-model
view with the RESET THE VOLUME MODEL soft key, see "3-D
view in the Test Run operating mode", page 590
