Danger
Attention
Attention
Danger
During operation several of the motor parts may be either live or moving and are thus extremely
dangerous.
Never perform any kind of work on the motor (e.g., open the terminal box, make or break
connections) while it is under power.
Temperatures of up to 145 °C may occur on the motor surfaces.
When connecting the fan, ensure that the direction of rotation is correct.
The arrow symbol on the fan housing indicates the correct direction.
After mounting the motor you must verify the trouble-free functioning of the brake.
On motors that are equipped with a feather key at the shaft end, the feather key must be secured
against ejection.
You will find further information on the safe and trouble-free handling of your motor in the
operating instructions that accompany each unit.

3 Errors and error messages
Danger
3.1 Introduction
Errors in the drives of machine tools usually lead to an error message on the monitors of the control.
But not all error conditions of the machine generate an error message.
Therefore, here you find an overview of errors with notes and tips on how to proceed.
Permanent and reproducible errors
Sporadic and nonreproducible errors
An interruption in the electrical cabinet or a defective device are a permanent error.
If you can generate an error on a machine at any time, the error is reproducible.
By their very nature, permanent and reproducible errors can be located more easily.
Sporadic errors may, for example, be caused by a loose connection, shielding problems or
interference.
Non-reproducible errors cannot be generated reliably by certain actions. They "randomly" appear on the
machine.
To investigate sporadic, non-reproducible errors, also integrated diagnosis tools in the control (e.g., an
integrated log, a PLC logic diagram or an integrated oscilloscope) can be used.
In case of errors that may lead to very high currents, e.g. ground fault or short circuit
in the drive, do not switch on the machine again!
First ensure that there are no defective units, cables, etc.
Then eliminate all ground faults and short circuits in the machine!

3.3 Error messages on the monitor of the control
Note
HEIDENHAIN inverter systems and HEIDENHAIN motors are usually operated with HEIDENHAIN
controls.
Errors on inverters and/or motors that occur when the machine is switched on or during operation are
ideally shown as errors on the monitor. The operator or the service engineer obtains information on
the possible causes of the error and on corrective action. In case of axis-specific errors, there is an axis
symbol (e.g. X) in the error text!
Example of an NC error message on the monitor of an iTNC 530:
If it is possible and makes sense, you may switch the control off and on again to observe
whether the error message is generated again afterwards.
List of NC error messages
PLC error messages In addition to the NC error messages defined by HEIDENHAIN, the machine manufacturer can define
June 2012 3 – 21
HEIDENHAIN has defined NC error messages. You can find the complete list of all NC error messages
for TNC controls on the TNCguide DVD in several languages and sorted by error numbers.
This TNCguide information is also available on our website www.heidenhain.de.
PLC error messages.
The manufacturer can define the machine behavior in case of a PLC error (NC stop, EMERGENCY
STOP, etc.). The machine can thus be protected additionally. The operator or the service engineer
obtains machine-specific information on the possible causes of the error and on corrective action
together with PLC error messages.
Example of an PLC error message on the monitor of an iTNC 530:
3.4 Log of the control
HEIDENHAIN controls feature a log. In these logs information, key strokes, error messages etc. are
recorded.
You will find information in the respective service manuals of the controls (e.g. SHB iTNC 530)!

4 Explanation of the LEDs
Note
4.1 Introduction
On the front of the compact inverters there are several LEDs for functional control.
Their meaning is described in this chapter.
The two red LEDs SH 1 or STO A and SH 2 or STO B (located at every axis and spindle output stage)
will be explained in detail:
Within the framework of standardization and adaptation to the machine directives 2006/42/EC
binding as of January 1, 2010, the designation of the enabling signals SH 1 (Safe Stop 1) and SH 2
(Safe Stop 2) was changed for inverter models from the current production program.
The signal "SH 1“ was renamed to "STO A“ (Safe Torque Off - channel A) and the signal "SH 2“
to "STO B“ (Safe-Torque Off - channel B).
Red LED SH 1 / STO A
Red LED SH 2 / STO B
The old red SH 1 LED has been superseded by the red STO.A LED.
SH 1 means "Safe Stop 1" (Sicherer Halt)
STO A means "Safe Torque Off cutout channel A“
SH 1 / STO A is indicated by a red LED on the inverter system
SH 1 / STO A is created by the processor of the HEIDENHAIN control.
SH 1 / STO A is low-active, i.e. line-break proof
If the processor is not ready for operation or if an error is active, SH 1 / STO A is output.
The red SH 1 / STO A LED and the green READY LED at the inverter can not be lit a the same time.
They are mutually locked.
The old red SH 2 LED has been superseded by the red STO.B LED.
SH 2 means "Safe Stop 2" (Sicherer Halt 2)
STO B means "Safe Torque Off cutout channel B“
SH 2 / STO B is indicated by a red LED on the inverter system
SH 2 / STO B is created by the controller of the HEIDENHAIN control.
SH 2 / STO B is low-active, i.e. line-break proof
If an axis or spindle is not controlled, SH 2 / STO B is active and the red LED is on.
This is, for example, the case with clamped axes or if a spindle is not controlled.
SH 2 / STO B and READY are then lit at the same time.
