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.

WARNING This symbol indicates a possibly

dangerous situation that may cause light injuries if

not avoided.

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 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

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 620 817600-03

TNC 620 E 817601-03

TNC 620 Programming Station 817605-03

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:

All TNC functions that have no connection with

cycles are described in the User's Manual of the TNC

620. 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

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.

Optional parameters

10 HEIDENHAIN | TNC 620 | User’s manual for cycle programming | 9/2015

Optional parameters

The comprehensive cycle package is continuously further

developed by HEIDENHAIN. Every new software version thus

may also introduce new Q parameters for cycles. These new Q

parameters are optional parameters, some of which have not been

available in previous software versions. Within a cycle, they are

always provided at the end of the cycle definition. You will find an

overview of the optional Q parameters that have been added with

this software version in the "New and changed cycle functions of

software 81760x-02" section. You can choose whether to define

optional Q parameters or delete them with the NO ENT key. You

can also adopt the default value. If you have accidentally deleted an

optional Q parameter or if you would like to extend cycles in your

existing programs after a software update, you can include optional

Q parameters in cycles when needed. The following steps describe

how this is done:

To insert optional Q parameters in existing programs:

Call the cycle definition

Press the right arrow key until the new Q parameters are

displayed

Apply the default value or enter a value

To transfer the new Q parameter, exit the menu by pressing

the right arrow key once again or by pressing END

If you do not wish to apply the new Q parameter, press the

NO ENT key

Compatibility

The majority of part programs created on older HEIDENHAIN

contouring controls (TNC 150 B and higher) can be executed with

this new software version of the TNC 620. Even if new, optional

parameters ("Optional parameters") have been added to existing

cycles, you can normally continue running your programs as usual.

This is achieved by using the stored default value. The other way

round, if a program created with a new software version is to be

run on an older control, you can delete the respective optional

Q parameters from the cycle definition with the NO ENT key.

In this way you can ensure that the program will be downward

compatible. If NC blocks contain invalid elements, the TNC will

mark them as ERROR blocks when the file is opened.
