2.3 With inverter systems, especially remember

Danger

During operation several parts of the inverter systems may be live and are thus extremely dangerous.

This includes ...

the primary connection with 3 phases, 400 Vac +/- 10 % (may be higher in case of an error)

the conductor bars with 565 Vdc or 650 Vdc (may be higher in case of an error)

the motor outputs

the connecting terminals for the braking resistor

Photo: Example with UV 130 and power modules

Danger

Switch off the machine and wait at least 5 minutes; then ensure that it is not under voltage before removing the conductor bars or disconnecting the braking resistor.

See label on the protective caps!

2.4 With motors, especially remember

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.

Attention

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.

Attention

After mounting the motor you must verify the trouble-free functioning of the brake.

Danger

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

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	An interruption in the electrical cabinet or a defective device are a permanent error.
reproducible errors	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 and non-	Sporadic errors may, for example, be caused by a loose connection, shielding problems or
reproducible errors	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.

Danger

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!

HEIDENHAIN Service Manual for Inverter Systems and Motors

3.3 Error messages on the monitor of the control

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:

		Note
		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	HEIDENHAIN has defined NC error messages. You can find the complete list of all NC error messages
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	In addition to the NC error messages defined by HEIDENHAIN, the machine manufacturer can define
	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)! Example of NC error messages in the log of an iTNC 530:

4 Explanation of the LEDs

4.1 Introduction

Red LED

SH 1 / STO A

Red LED

SH 2 / STO B

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:

Note

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).

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.
