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

2.1 Introduction
The safety precautions below are provided to ensure your personal safety and the safety of the
machine tool.
Please read this information carefully before you start servicing the machine!
2.2 Overview
Equipment ground
Ensure that the equipment ground is continuous!
Interruptions in the grounding conductor may cause damage or injury to property or persons.
Zero potential
Fundamental
knowledge
Know-how and
competence
Ensure that the main switch of the control is switched off and that connected devices are not
under power when you engage or disengage any connectors or terminals.
Take precautions against restart!
Use an appropriate voltage test unit to ensure that the unit is not under voltage!
In order to be able to judge the behavior of an NC controlled machine, service engineers need
to have fundamental knowledge of controls, encoders, drives, electronics and mechanics.
Inappropriate use may cause considerable damage to persons or property.
Technicians who work on the electrical system of the machine must have the required know-how
and competence.
Suitable tools
Use suitable tools, e.g. insulated screwdrivers and pincers!

The maximum mean dc voltage of the PLC inputs is 31 V.
Always secure vertical axes to prevent them from falling down before you perform tests on these
axes!
Incorrect or non-optimized input values can lead to faulty machine performance and therefore
to serious injury to persons and damage to equipment.
Machine parameters may only be changed by or after consultation with the machine
manufacturer!
Uncontrolled axis and spindle movements must be expected.
Settings that have an effect on the control's feedback loops may only be altered when the

4 Error messages
Note
4.1 Introduction
The iTNC 530 features a comprehensive integral monitoring system for the prevention of input
or operation errors, as well as for identification and diagnosis of technical defects on the control
and the connected devices. The monitoring system is an integral component of the iTNC hardware
and software and is active as long as the control is switched on. The presence of a technical fault
or an operation error is made known through a plain-language message.
Moreover, the machine manufacturer can define specific PLC error messages.
Type of
error message
PLC error messages
Machine-specific error messages
Are defined by the machine manufacturer (e.g., coolant pump defective, protective door
open)
The machine manufacturer defines how the control reacts to a PLC error message (NC Stop,
EMERGENCY STOP, etc.)
The machine manufacturer defines whether the control can still be operated or has to be rebooted
after a PLC error message.
If you have any questions, please contact your machine manufacturer.
NC error messages
Are part of the HEIDENHAIN NC software.
Can be subdivided into error messages that result from operation, programming and machine
applications and those that indicate a technical defect (devices, electronic and mechanical
components, etc.)
HEIDENHAIN defines how the control reacts to an NC error message (NC Stop, EMERGENCY
STOP, etc.)
HEIDENHAIN defines whether the control can still be operated or has to be rebooted after
an NC error message.
If you have any questions, please contact your machine manufacturer and/or HEIDENHAIN.
Is the displayed error message an NC or PLC error message?
Call the ERR window or the log to answer this question:

No error numbers are assigned to NC error messages that begin with N-1.
Operating-system error messages
Often contain the note CHILD PROCESS ERROR.
The control cannot be operated any more and has to be rebooted.
If you have any questions, please contact your machine manufacturer and/or HEIDENHAIN.

Reaction of
control and
machine
Display only
A message (info, warning, error) is only displayed.
The machine does not react; programs are not stopped.
The error message can be acknowledged anytime.
Feed stop
The feed-rate enable is reset. The "F" symbol for the feed rate is highlighted.
The axes are braked at the nominal value characteristic.
I.e., the contour of the workpiece is usually not damaged.
Once the error message has been acknowledged, the machine continues to operate at the set feed
rate.
NC Stop
The running NC program is stopped. The control-in-operation symbol (STIB) flashes.
The axes are braked at the nominal value characteristic.
I.e., the contour of the workpiece is usually not damaged.
After the error message has been acknowledged, the NC program can be restarted at the position
where it was interrupted (NC START key).
Program cancelation
The running NC program is canceled (internal stop).
The axes are braked at the nominal value characteristic.
I.e., the contour of the workpiece is usually not damaged.
After the error message has been acknowledged, the NC program needs to be restarted
(GOTO 0, NC START).
Automatic
generation of
service files
EMERGENCY STOP
An EMERGENCY STOP is triggered at the machine.
Axes and spindles decelerate at the current limit; the machine must be brought to a standstill as
quickly as possible.
The contour of the workpiece is not taken into account and may be damaged.
After the error message was acknowledged, the machine must be switched on completely.
Now, the PLC program can be restarted (GOTO 0, NC START).
RESET
An EMERGENCY STOP is triggered at the machine.
Axes and spindles decelerate at the current limit; the machine must be brought to a standstill as
quickly as possible.
The contour of the workpiece is not taken into account and may be damaged.
The error message cannot be acknowledged. The control must be shut down and restarted.
Now, the PLC program can be restarted (GOTO 0, NC START).
In the event of serious NC software errors or especially defined PLC error messages, service files are
generated automatically.
See ”Creating and reading out service files” on page 7 – 75.
