Foreword
This Technical Manual has been written for all machine tool manufacturers and
distributors. It contains all of the information necessary for the mounting,
electrical connection, commissioni ng and PLC prog ramming of HEIDENHAIN
contouring controls.
Every time the hardware or software of HEIDENHAIN's contouring control is
updated, you will receive a set of supplementary pages free-of-charge. Always
sort these pages into your Technical Manual immediately. In this way, your
manual will always be up-to-date.
You can use extracts from this manual to supplement your machine
documentation. If you increase the size of the manual format (17 cm x 24 cm)
by the factor 1.225, you will have DIN A4 format.
No documentation can be perfect. To stay up to date, documentation must
change constantly. It also thrives on your comments and suggestions for
improvement. Please help us by sending us your ideas.

2 Introduction
2.1 General Information
HEIDENHAIN contouring controls are designed for use with milling, drilling
and boring machines as well as machining centers.
The iTNC 530 features integral digital drive control and controls the power
stages via PWM signals.
Integration of the drive controllers in the iTNC 530 offers the following
advantages:
n All the software is contained centrally in the NC; this means that the
individual components of the NC such as feed axes, spindle, NC or PLC are
optimally matched.
n High control quality, because the position controller, speed controller and
current controller are combined into one unit.
n The same functions are available for commissioning, optimizing and
diagnosing feed drives as well as spindles.
The iTNC 530 offers digital control for up to five or nine axes and for spindle
speeds up to 40 000 rpm.
The iTNC 530 is designed for connection of a compact or modular inverter
system. Thus, together with HEIDENHAIN motors, a complete control
package including servo drive can be supplied (see Technical Manual "Inverter
Systems and Motors").

2.4 Software
2.4.1 Designation of the Software
The iTNC 530 features a separate software for the NC and the PLC. The NC
software is identified with an eight-digit number.
If you press the MOD key in any operating mode, you can display the ID
numbers of the NC software, the DSP software (DSP1, DSP2) and the current-
controller software (ICTL1, ICTL2).
Type The iTNC 530 is shipped with the following NC software version:
Due to restrictions on the export of the iTNC 530, HEIDENHAIN can also
supply a special export version. This export version differs from the standard
control though the installed NC software type. HEIDENHAIN releases a new
NC software type whenever it introduces extensive new functions.
2.4.2 PLC Software
The PLC software is stored on the hard disk of the TNC. You can order a PLC
basic program directly from HEIDENHAIN. With the PLC development
software PLCdesign, the PLC program can very easily be adapted to the
requirements of the machine.
