Foreword
ThisTechnicalManualhasbeenwrittenforallmachinetoolmanufacturersand
distributors. It contains all of the information necessary for the mounting,
electrical connection, commissioning and PLC programming of HEIDENHAIN
contouring controls.
Every time the hardware or software of HEIDENHAIN's contouring control is
updated,you will receive a set ofsupplementary 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:
nAll 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.
nHigh control quality, because the position controller, speed controller and
current controller are combined into one unit.
nThe 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").

UV 105 Power Supply Unit
The UV 105 serves to supply the power to the CC
422 if a non-HEIDENHAIN inverter is used, or, if
required, to supply additional power if a
HEIDENHAIN inverter is used, See “Power
Supply for the iTNC 530” on page 3 – 12.
If a non-HEIDENHAIN inverter system is used,
the adapter connector is connected to X69 of the
UV 105.
The cover for the UV 105 and the adapter
connector for X69 are included in the items
supplied.
