TNC model, software and features
TNC model, software and features
This manual describes functions and features provided by TNCs as
of the following NC software numbers.
TNC model NC software number
TNC 640 340590-05
TNC 640 E 340591-05
TNC 640 Programming Station 340595-05
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 therefore 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.
User's Manual:
All TNC functions that have no connection with
cycles are described in the User's Manual of the TNC
640. Please contact HEIDENHAIN if you require a
copy of this User's Manual.
ID of User's Manual for conversational programming:

TNC model, software and features
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.
Intended place of operation
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.

Optional parameters
Optional parameters
The comprehensive cycle package is continuously further
developed by HEIDENHAIN. Every new software version thus
may also introduce new Q parameters for cycles. These new Q
parameters are optional parameters, some of which have not been
available in previous software versions. Within a cycle, they are
always provided at the end of the cycle definition. You will find an
overview of the optional Q parameters that have been added with
this software version in the "New and changed cycle functions of
software 34059x-05" section. You can choose whether to define
optional parameters or delete them with the NO ENT key. You can
also adopt the default value. If you have accidentally deleted an
optional Q parameter or if you would like to extend cycles in your
existing programs after a software update, you can include optional
Q parameters in cycles when needed. The following steps describe
how this is done:
To insert optional Q parameters in existing programs:
Call the cycle definition
Press the right arrow key until the new Q parameters are
displayed
Apply the default value or enter a value
To transfer the new Q parameter, exit the menu by pressing
the right arrow key once again or by pressing END
If you do not wish to apply the new Q parameter, press the
NO ENT key
Compatibility
The majority of part programs created on older HEIDENHAIN
contouring controls (TNC 150 B and higher) can be executed with
this new software version of the TNC 640. Even if new, optional
parameters ("Optional parameters") have been added to existing
cycles, you can normally continue running your programs as usual.
This is achieved by using the stored default value. The other way
round, if a program created with a new software version is to be
run on an older control, you can delete the respective optional
Q parameters from the cycle definition with the NO ENT key.
In this way you can ensure that the program will be downward
compatible. If NC blocks contain invalid elements, the TNC will
mark them as ERROR blocks when the file is opened.
