1 How to use the iTNC 530 HSCI Service Manual

1.1 Target group

This Service Manual has been written for specialist electricians for service, maintenance and

commissioning.

Specialists who perform work on the electrical system of a machine tool and its components must

have the required technical knowledge and competence.

1.2 About this manual

Objective This Service Manual assists service staff in the field in diagnosing and correcting errors on

machine tools equipped with the HEIDENHAIN control iTNC 530 HSCI.

HSCI This Service Handbook was specifically written for field service of iTNC 530 with HSCI.

The HSCI, the HEIDENHAIN Serial Controller Interface, connects the main computer, controller(s)

and other control components by means of a bus system.

The diagnostic functions of the iTNC 530 HSCI are the same as those of the iTNC 530 plus a special

HSCI bus diagnostics.

Contents This manual includes:

 Specific explanations of the HEIDENHAIN Serial Controller Interface (HSCI)

 Error messages and types of errors that indicate technical defects

 Information on possible error causes

 Descriptions for error diagnosis

 Application descriptions of the diagnosis tools

 Information on corrective action

 Data backup instructions

 Theoretical explanations of functions and their correlations

The ”List of NC error messages” on page 4 – 27 and the ”Overview of possible errors” on page 5 –

51 contain many references to the descriptions for error diagnosis.

You will find these descriptions in the chapters of this Service Manual sorted by topics.

Commissioning

support?

The Service Manual does not provide any commissioning support!

Validity This manual comprises the servicing possibilities with the control hardware and software

up-to-date at the publishing date of this manual. The servicing possibilities of your equipment may

differ from those described here. The descriptions also provide information on any differences in

servicing that are due to changes in the hardware or software.

This manual is valid for:

 Single-processor iTNC 530 with HSCI and NC software 606420 / 421 (without "Functional Safety")

Prerequisites For the instructions for the field service it is assumed that ...

 the machine had been working perfectly before the error occurred.

 only original spare parts are used!

Note

For the field service of iTNC 530 without HSCI, refer to the iTNC 530 Service Manual.

Note

Basic knowledge of Windows is required for some of the descriptions in this Service Manual that

deal with the use of a service laptop.
