TNC Model, Software and Features

This manual describes functions and features provided by TNCs as of

the following NC software numbers.

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

version of the TNC has the following limitations:

 Linear movement is possible in no more than 4 axes simultaneously.

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 not be among the features provided by

your machine tool.

Some TNC functions have to be implemented by the machine tool

builder and are therefore not universally available on all machines.

These functions include:

 Probing function for the 3-D touch probe

 Tool measurement with the TT 130

 Rigid tapping

 Returning to the contour after an interruption

In addition, the iTNC 530 also has two software option packets that

can be enabled by you or your machine tool builder. Each packet is to

be enabled separately and contains the following respective functions:

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.

Location of use

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.

Touch Probe Cycles User’s Manual:

All of the touch probe functions are described in a separate

manual. Please contact HEIDENHAIN if you require a copy

of this User’s Manual. ID number: 375 319-xx.

HEIDENHAIN iTNC 530 7

Functions new since the predecessor versions

340 422-xx and 340 423-xx

 The form-based smarT.NC operating mode, for which separate user

documentation is available, was introduced. In connection with this

the TNC operating panel was enhanced. There are some new keys

available for quicker navigation within smarT.NC (see “Operating

panel” on page 39).

 The single-processor versions supports pointing devices (mice) via

the USB 2.0 interface.

 The tooth feed f

z

and feed per revolution f

u

can now be defined as

alternate feed entries (see “Functions for setting the feed rate” on

page 105).

 New CENTERING cycle (see “CENTERING (Cycle 240)” on page 275)

 New M function M150 for suppressing limit switch messages (see

“Suppress limit switch message: M150” on page 249)

 M128 is now also permitted for mid-program startup (see “Mid-

program startup (block scan)” on page 565).

 The number of available Q parameters was expanded to 2000 (see

“Principle and Overview” on page 502).

 The number of available label numbers was expanded to 1000. Now

label names can be assigned as well (see “Labeling Subprograms

and Program Section Repeats” on page 486).

 In the Q parameter functions FN9 to FN12 you can now also assign

label names as jump targets (see “If-Then Decisions with

Q Parameters” on page 510).

 Selectively machine points from a point table (see “Hiding single

points from the machining process” on page 269).

 The current time is also shown in the additional status display

window (see “General program information” on page 44).

 Several columns were added to the tool table (see “Tool table:

Standard tool data” on page 146).

 The Test Run can now also be stopped and continued within

machining cycles (see “Running a program test” on page 559).

8

Functions changed since the predecessor

versions 340 422-xx and 340 423-xx

 The layouts of the status display and additional status display were

redesigned (see “Status Displays” on page 43).

 Software 340 490 no longer supports the small resolution in

combination with the BC 120 screen (see “Visual display unit” on

page 37).

 New key layout of the TE 530 B keyboard unit (see “Operating

panel” on page 39)

 The entry range for the EULPR precession angle in the PLANE

EULER function was expanded (see “Defining the Machining Plane

with Euler Angles: EULER PLANE” on page 460).

 The plane vector in the PLANE EULER function no longer has to be

entered in standardized form (see “Defining the Machining Plane

with Two Vectors: VECTOR PLANE” on page 462).

 Positioning behavior of the CYCL CALL PAT function modified (see

“Calling a cycle in connection with point tables” on page 271)

 The tool types available for selection in the tool table were increased

in preparation for future functions.

HEIDENHAIN iTNC 530 9

New/changed descriptions in this manual

 New key layout of the TE 530 B keyboard unit (see “Operating

panel” on page 39)

 The “Standard File Management” (file management without

directory structure) chapter was removed from the manual.
