About this manual

Safety precautions

Comply with all safety precautions indicated in this document and

in your machine tool builder's documentation!

Precautionary statements warn of hazards in handling software

and devices and provide information on their prevention. They are

classified by hazard severity and divided into the following groups:

DANGER

Danger indicates hazards for persons. If you do not follow the

avoidance instructions, the hazard will result in death or severe

injury.

WARNING

Warning indicates hazards for persons. If you do not follow the

avoidance instructions, the hazard could result in death or

serious injury.

CAUTION

Caution indicates hazards for persons. If you do not follow the

avoidance instructions, the hazard could result in minor or

moderate injury.

NOTICE

Notice indicates danger to material or data. If you do not follow

the avoidance instructions, the hazard could result in things

other than personal injury, like property damage.

Sequence of information in precautionary statements

All precautionary statements comprise the following four sections:

Signal word indicating the hazard severity

Type and source of hazard

Consequences of ignoring the hazard, e.g.: "There is danger of

collision during subsequent machining operations"

Escape – Hazard prevention measures

Informational notes

Observe the informational notes provided in these instructions to

ensure reliable and efficient operation of the software.

In these instructions, you will find the following informational

notes:

The information symbol indicates a tip.

A tip provides important additional or supplementary

information.

This symbol prompts you to follow the safety

precautions of your machine tool builder. This symbol

also indicates machine-dependent functions. Possible

hazards for the operator and the machine are described

in the machine manual.

The book symbol represents a cross reference to

external documentation, e.g. the documentation of your

machine tool builder or other supplier.

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 640 340590-08

TNC 640 E 340591-08

TNC 640 Programming station 340595-08

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.

Operating instructions:

All TNC functions not connected to the cycles are

described in the TNC 640 User’s Manual. Please contact

HEIDENHAIN if you require a copy of this User's

Manual.

Feature Content Level (upgrade functions)

Along with software options, significant further improvements of

the TNC software are managed via the Feature Content Level (FCL)

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.
