TNC Model, Software and Features
This manual describes functions and features provided by TNCs as of
the following NC software numbers.
The suffix E indicates the export version of the TNC. The export
version of the TNC has the following limitations:
Linear movement is possible in no more than 4 axes simultaneously.
The machine tool builder adapts the useable features of the TNC to his
machine by setting machine parameters. Some of the functions
described in this manual may not be among the features provided by
your machine tool.
TNC functions that may not be available on your machine include:
Tool measurement with the TT
Please contact your machine tool builder to become familiar with the
features of your machine.
Many machine manufacturers, as well as HEIDENHAIN, offer
programming courses for the TNCs. We recommend these courses as
an effective way of improving your programming skill and sharing
information and ideas with other TNC users.

Feature content level (upgrade functions)
Along with software options, significant further improvements of the
TNC software are managed via the Feature Content Level. Functions
subject to the FCL are not available simply by updating the software
on your TNC. These functions are identified in the manual with FCL n,
where n indicates the sequential number of the feature content level.
You can purchse a code number in order to permanently enable the
FCL functions. For more information, contact your machine tool
builder or HEIDENHAIN.
Location of use
The TNC complies with the limits for a Class A device in accordance
with the specifications in EN 55022, and is intended for use primarily
in industrially-zoned areas.

Functions included in 340 49x-01 new since the
predecessor versions 340 422-xx and 340 423-xx
A new form-based operating mode, smarT.NC, introduced. These
cycles are described in a separate user's document. In connection
with this the TNC operating panel was enhanced. There are some
new keys available for quicker navigation within smarT.NC (see
“Operating panel” on page 40).
The single-processor versions supports pointing devices (mice) via
the USB interface.
The tooth feed f
z
and feed per revolution fu can now be defined as
alternate feed entries See table “”.
New CENTERING cycle (see “CENTERING (Cycle 240)” on page
305)
New M function M150 for suppressing limit switch messages (see
“Suppress limit switch message: M150” on page 279)
M128 is now also permitted for mid-program startup (see “Mid-
program startup (block scan)” on page 600).
The number of available Q parameters was expanded to 2000 (see
“Principle and Overview” on page 532).
The number of available label numbers was expanded to 1000. Now
label names can be assigned as well (see “Labeling Subprograms
and Program Section Repeats” on page 516).
In the Q parameter functions FN9 to FN12 you can now also assign
label names as jump targets (see “If-Then Decisions with
Q Parameters” on page 540).
Selectively machine points from a point table (see “Hiding single
points from the machining process” on page 299).
The current time is also shown in the additional status display
window (see “General program information” on page 45).
Several columns were added to the tool table (see “Tool table:
Standard tool data” on page 166).
The Test Run can now also be stopped and continued within
machining cycles (see “Running a program test” on page 594).
HEIDENHAIN iTNC 530 9
TNC Model, Software and Features
New functions with 340 49x-02
DXF files can be opened directly on the TNC, in order to extract
contours into a plain-language program (see “Generating Contour
Programs from DXF Data (Software Option)” on page 252)
3-D line graphics are now available in the Programming and Editing
operating mode (see “3-D Line Graphics (FCL 2 Function)” on page
128)
The active tool-axis direction can now be set as the active machining
direction for manual operation (see “Setting the current tool-axis
direction as the active machining direction (FCL 2 function)” on page
80)
The machine manufacturer can now define any areas on the
machine for collision monitoring (see “Dynamic Collision Monitoring
(Software Option)” on page 81)
Instead of the spindle speed S you can now define the cutting speed
Vc in m/min (see “Calling tool data” on page 175)
The TNC can now display freely definable tables in the familiar table
view or as forms (see “Switching between table and form view” on
page 196)
The function for converting FK programs to H was expanded.
Programs can now also be output in linearized format (see
“Converting FK programs into HEIDENHAIN conversational format”
on page 236)
You can filter contours that were created using external
programming systems (see “Filtering Contours (FCL 2 Function)”
on page 514)
For contours which you connect via the contour formula, you can
now assign separate machining depths for each subcontour (see
“Defining contour descriptions” on page 433)
The single-processor version now supports not only pointing
devices (mice), but also USB block devices (memory sticks, disk
drives, hard disks, CD-ROM drives) (see “USB devices on the TNC
(FCL 2 function)” on page 113)

TNC Model, Software and Features
Functions changed in 340 49x-01 since the
predecessor versions 340 422-xx and 340 423-xx
The layouts of the status display and additional status display were
redesigned (see “Status Displays” on page 44).
Software 340 490 no longer supports the small resolution in
combination with the BC 120 screen (see “Visual display unit” on
page 39).
New key layout of the TE 530 B keyboard unit (see “Operating
panel” on page 40)
The entry range for the EULPR precession angle in the PLANE EULER
function was expanded (see “Defining the Machining Plane with
Euler Angles: EULER PLANE” on page 490)
The plane vector in the PLANE EULER function no longer has to be
entered in standardized form (see “Defining the Machining Plane
with Two Vectors: VECTOR PLANE” on page 492)
Positioning behavior of the CYCL CALL PAT function modified (see
“Calling a cycle in connection with point tables” on page 301)
The tool types available for selection in the tool table were increased
in preparation for future functions.
Instead of the last 10, you can now choose from the last 15 selected
files (see “Choosing one of the last files selected” on page 105)
HEIDENHAIN iTNC 530 11
TNC Model, Software and Features
Functions changed in 340 49x-02
Access to the preset table was simplified. There are also new
possibilities for entering values in the preset table See table
“Manually saving the datums in the preset table”
In inch-programs, the function M136 (feed rate in 0.1 inch/rev) can
no longer be combined with the function FU
The feed-rate potentiometers of the HR 420 are no longer switched
over automatically when the handwheel is selected. The selection is
made via soft key on the handwheel. In addition, the pop-up window
for the active handwheel was made smaller, in order to improve the
view of the display beneath it (see “Potentiometer settings” on
page 60)
The maximum number of contour elements for SL cycles was
increased to 8192, so that much more complex contours can be
machined (see “SL Cycles” on page 397)
FN16: F-PRINT: The maximum number of Q-parameter values that
can be output per line in the format description file was increased to
32 (see “FN16: F-PRINT: Formatted output of texts or Q parameter
values” on page 548)
The soft keys START and START SINGLE BLOCK in the Program
Test mode of operation were switched, so that the soft-key
alignment is the same in all modes of operation (Programming and
Editing, smarT.NC, Test) (see “Running a program test” on page
594)
The design of the soft keys was revised completely
