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 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.

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 128 771841-02

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:

Probing functions for the 3-D touch probe

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.

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.
