The machine tool builder adapts the usable features of the TNC to his
machine by setting machine parameters. Some of the functions
described in this manual may therefore not be among the features
provided by the TNC on your machine tool.
TNC Model, Software and Features
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.

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 (FCL)
upgrade functions. Functions subject to the FCL are not available
simply by updating the software on your TNC.
All upgrade functions are available to you without surcharge
when you receive a new machine.
Upgrade functions are identified in the manual with FCL n, where n
indicates the sequential number of the feature content level.
You can purchase a code number in order to permanently enable the
FCL functions. For more information, contact your machine tool
builder or HEIDENHAIN.

page 83)
New key layout of the TE 530 B keyboard unit (see “Operating

options 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 FU function.
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.
The maximum number of contour elements for SL cycles was
increased to 8192, so that much more complex contours can be
machined (see User's Manual for Cycles).
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.
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 “Executing a test run” on page 615)

In Cycle 22 you can now define a tool name also for the coarse
roughing tool (see User's Manual Cycles).
In the PLANE function, an FMAX can now be programmed for the
automatic rotary positioning (see “Automatic positioning:
MOVE/TURN/STAY (entry is mandatory)” on page 484)
When running programs in which non-controlled axes are
programmed, the TNC now interrupts the program run and displays
a menu for returning to the programmed position (see
“Programming of noncontrolled axes (counter axes)” on page 622)
The tool usage file now also includes the total machining time,
which serves as the basis for the progress display in percent in the
Program Run, Full Sequence mode.
The TNC now also takes the dwell time into account when
calculating the machining time in the Test Run mode (see
“Measuring the machining time” on page 611)
Arcs that are not programmed in the active working plane can now
also be run as spatial arcs (see “Circular path C around circle center
CC” on page 232)

by the machine tool builder (see “Pocket table for tool changer” on
page 188)

improvements have been made (see “Additional status displays” on
page 91):
A new overview page with the most important status displays
was introduced.
The individual status pages are now displayed as tabs (as in
smarT.NC). The individual tabs can be selected with the Page soft
keys or with the mouse.
The current run time of the program is shown in percent by a
progress bar.
The tolerance values set in Cycle 32 are displayed.
Active global program settings are displayed, provided that this
software option was enabled.
The status of the Adaptive Feed Control (AFC) is displayed,
provided that this software option was enabled.

The pocket-, stud- and slot-milling cycles 210 to 214 were removed
from the standard soft-key row (CYCL DEF >
POCKETS/STUDS/SLOTS). For reasons of compatibility, the cycles
will still be available, and can be selected via the GOTO key.
The soft-key rows in the Test Run operating mode were modified to
those of the smarT.NC operating mode.

"Managing more than one block of calibrating data", page 573)
During tilting in the Distance-To-Go mode, the PLANE function now
shows the angle actually left to be traversed until the target position
(see “Position display” on page 469)
