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 address: tnc-userdoc@heidenhain.de.

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: 1096886-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.
