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.

Control model, software and features

This manual describes functions and features provided by controls

as of the following NC software numbers.

Control model NC software number

TNC 620 817600-05

TNC 620 E 817601-05

TNC 620 Programming Station 817605-05

The suffix E indicates the export version of the control. The

following software options are unavailable or only available to a

limited extent in the export version:

Advanced Function Set 2 (option 9) limited to four-axis

interpolation

The machine manufacturer adapts the usable features of the

control to his machine by the setting machine parameters. Some of

the functions described in this manual may therefore not be among

the features provided by the control on your machine tool.

Control functions that may not be available on your machine

include:

Tool measurement with the TT

In order to find out about the actual features of your machine,

please contact the machine manufacturer.

Many machine manufacturers, as well as HEIDENHAIN, offer

programming courses for the HEIDENHAIN controls. Participation

in one of these courses is recommended to familiarize yourself

thoroughly with the control's functions.

Cycle Programming User's Manual:

All of the cycle functions (touch probe cycles and fixed

cycles) are described in the Cycle Programming User's

Manual. If you need this user's manual, please contact

HEIDENHAIN if required. ID: 1096886-xx
