The suffix E indicates the export version of the TNC. The export version of the TNC has the following limitations:

Simultaneous linear movement in up to 4 axes

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 not be among the features provided by the TNC on 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 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.

Functions changed in 340 49x-01 since the predecessor versions 340 422-xx/340 423-xx

The layouts of the status display and additional status display were redesigned (see “Status Displays” on page 55).

Software 340 490 no longer supports the small resolution in combination with the BC 120 screen (see “Visual display unit” on page 49).

New key layout of the TE 530 B keyboard unit (see “Keyboard” on page 51)

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 551)

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 553)

Positioning behavior of the CYCL CALL PAT function modified (see “Calling a cycle in connection with point tables” on page 356)

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 127)

14

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 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 (see “Potentiometer settings” on page 76).

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 447).

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 “FN 16: F-PRINT: Formatted output of text and Q parameter values” on page 614).

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 673)

The design of the soft keys was revised completely.

Changed functions with 340 49x-03

In Cycle 22 you can now define a tool name for the coarse roughing tool as well (see “ROUGH-OUT (Cycle 22)” on page 456).

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 560).

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 677).

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 (see “Tool usage test” on page 683).

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 669).

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 254).

The EDIT OFF/ON soft key on the pocket table can be deactivated by the machine tool builder (see “Pocket table for tool changer” on page 207).

The additional status display has been revised. The following improvements have been introduced (see “Additional status displays” on page 57):

A new overview page with the most important status displays were 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.

16

Changed functions with 340 49x-04

DCM: Retraction after collision simplified (see “Early warning zone,” page 99)

The input range for polar angles was increased (see “Circular path CP around pole CC” on page 263)

The value range for Q-parameter assignment was increased (see “Programming notes,” page 597)

The pocket-, studand 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

Windows XP is now used on the dual-processor version (see “Introduction” on page 768)

Conversion from FK to H was moved to the special functions (SPEC FCT) (see “Converting FK programs into HEIDENHAIN conversational format” on page 272)

Filtering of contours was moved to the special functions (SPEC FCT) (see “Filtering Contours (FCL 2 Function)” on page 574)
