HEIDENHAIN iTNC 530 5

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

iTNC 530, HSCI and HeROS 5 606 420-02

iTNC 530, HSCI and HeROS 5 606 421-02

iTNC 530 Programming Workstation, HeROS 5

The suffix E indicates the export version of the TNC. The export versions of the TNC have the following limitations:

 Simultaneous linear movement in up to 4 axes

HSCI (HEIDENHAIN Serial Controller Interface) identifies the new hardware platform of the TNC controls.

HeROS 5 identifies the operating system of HSCI-based TNC controls. 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 Model, Software and Features

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.

606 421-02

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 a separate manual. Please contact HEIDENHAIN if you require a copy of this User’s Manual. ID: 670 388-xx

smarT.NC user documentation:

The smarT.NC operating mode is described in a separate Pilot. Please contact HEIDENHAIN if you require a copy of this Pilot. ID: 533 191-xx.

TNC Model, Software and Features

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.
