About this manual
About this manual
The symbols used in this manual are described below.
This symbol indicates that important information
about the function described must be considered.
This symbol indicates that there is one or more
of the following risks when using the described
function:
Danger to workpiece
Danger to fixtures
Danger to tool
Danger to machine
Danger to operator
This symbol indicates a possibly dangerous situation
that may cause light injuries if not avoided.
This symbol indicates that the described function
must be adapted by the machine tool builder. The
function described may therefore vary depending on
the machine.
This symbol indicates that you can find detailed
information about a function in another manual.
Would you like any changes, or have you found any errors?
We are continuously striving to improve our documentation for you.
Please help us by sending your requests to the following e-mail

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 320 771851-01
TNC 320 Programming Station 771855-01
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 for Cycle Programming:
All of the cycle functions (touch probe cycles and
fixed cycles) are described in the Cycle Programming
User’s Manual. Please contact HEIDENHAIN if you
require a copy of this User's Manual. ID: 1096959-xx

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.
