Safe motor feedback systems

About this document

Please read these operating instructions carefully before using the safe motor

feedback system or mounting it, putting it into operation or servicing it. The manu‐

facturer can only guarantee the safety function if these operating instructions are

followed consistently.
This document is an original document.

1.1 Purpose of this document

These operating instructions provide qualified technical personnel of the machine

manufacturer or the machine operator with instructions regarding the safe mount‐

ing, electrical installation, commissioning, operation, maintenance and decom‐

missioning of the safe motor feedback system.
These operating instructions must be made available to all those who work with

the safe motor feedback system.
Furthermore, planning and using safety-oriented sensors such as the safe motor

feedback system also requires technical skills that are not covered in this docu‐

ment. The official, legal and safety-relevant regulations for mounting and operat‐

ing the safe motor feedback system must always be complied with.

1.2 Symbols and document conventions

WARNING

A safety note informs you of real-world specifications for safely mounting and

installing the safe motor feedback system. This is intended to protect you

against accidents. Read and follow the safety notes carefully.

NOTE

Indicates useful tips and recommendations.

b

Instructions requiring specific action are indicated by an arrow. Carefully

read and follow the instructions for action.

Safety information

This chapter concerns your own safety and the safety of the system operator.

2.1 General safety notes

The national and international legal specifications apply to the installation and

use of the motor feedback system, to its commissioning and to technical inspec‐

tions repeated at regular intervals, in particular:

the Machinery Directive 2006/42/EC

the Equipment Directive 2009/104/EC

work safety regulations and safety regulations

any other relevant safety regulations

The manufacturer and operator of the machine, on which the safe motor feed‐

back system is used, are responsible for coordinating and complying with all

applicable safety specifications and regulations, in cooperation with the relevant

authorities.
The manufacturer of the drive system connected must have complied with the

safety requirements for the drive system design described in the technical infor‐

mation,“HIPERFACE DSL

®

 MASTER”.

2.2 Intended use

The motor feedback system is ideal for the dynamic and precise operation of

servo-control circuits, due to its equipment.
The overall system, consisting of encoder, evaluation system, servo inverter and

motor, forms a control circuit.
The safety-oriented use of safe motor feedback systems with a HIPERFACE DSL

®

interface concerns application in combination with servo systems that work with

three-phase AC synchronous motors and alternatively AC asynchronous motors.
The following information can be derived from the digital position signals of the

motor feedback system linked directly to a motor shaft:

(Rotational) speed information and commuting information in AC synchro‐

nous motors

(Rotational) speed information in asynchronous motors

The safe motor feedback system can be used in conjunction with a drive system

in accordance with IEC 61800-5-2, in safety applications up to category 3 and

PL d in accordance with EN ISO 13849 or SIL2 in accordance with IEC 61508 or

SIL CL3 in accordance with EN 62061.
The safety integrity level of the encoder is SIL 2. The systematic capability of the

encoder is SC 3. Only when applied in redundant architecture, the encoder can be

utilized for SIL 3 applications, otherwise, i.e. when used standalone, it shall be uti‐

lized maximum for SIL 2 applications.
It fulfills the requirements of the Machinery Directive 2006/42/EC and provides

support for the drive system in ensuring:

The safety functions, based on the safe absolute position information

The safety functions, based on the incremental position information

The safety functions only apply for a single motor revolution (singleturn).
In the case of safety functions that are based on the safe multiturn absolute posi‐

tion, the motor feedback system only supplies one channel without safety-related

diagnostics upon being switched on. The user must implement a second channel

by using other measures.
The user can provide this second channel by saving the position of the motor

feedback system before switching it off and comparing it to the starting position of

the motor feedback system, when switching it on the next time.
Use for multiturn absolute position safety-related purposes is possible only, if the

values match. Otherwise, the user must carry out a reference run. Without a sec‐

ond channel for the multiturn absolute position, a reference run must be carried

out each time, the motor feedback system is switched on to confirm the absolute

position.
The motor feedback system is not able to create a safe state for the drive system

independently. The drive system has to create the safe state as a response to an

error displayed by the motor feedback system.

WARNING

The safe motor feedback system shall be used only within the limits of the

prescribed and specified technical data, dimensions and tolerances of the

dimensional drawings and operating conditions, and the specified tightening

torques must be complied with.
If used in any other way or if alterations are made to the device – including in

the context of mounting and installation – this will render void any warranty

claims directed to SICK STEGMANN GmbH.

2.3 Improper use

The motor feedback system must be mounted and adjusted exactly in accordance

with the specifications of the installation instructions. Every faulty installation or

faulty adjustment of the encoder may impair the specified functions and data;

partial restriction or a total failure of the specified safety functions cannot be

ruled out in individual cases.

WARNING

If stimulations in the vicinity of the resonance frequencies cannot be reliably

ruled out in the application, suitable tests must be carried out for the entire

drive system during the initial commissioning of the system. Suitable reme‐

dial measures must be incorporated.

WARNING

Violations of the specified accuracy of the position value in the vicinity of the

resonance frequencies can occur, due to physical restraints. If the mechani‐

cal stimulation in the vicinity of the resonance frequencies has a very high

amplitude, faults or failures of the specified safety functions can occur. We

highly recommend to avoid operation in the vicinity of the resonance frequen‐

cies or at least to limit the amplitude.

2.4 Requirements for the qualification of personnel

The safe motor feedback system may be mounted, put into operation, checked,

maintained or used only by qualified safety personnel. A qualified person

is someone who has taken part in adequate technical training

has been instructed by a machine operator in machine operation and the

applicable safety guidelines and

has access to these operating instructions.

Project planning

WARNING

The supply voltage must be generated by PELV systems (EN 50178) and shall

be limited to 15 VDC by external means. The motor feedback system corre‐

sponds to protection class III according DIN EN 61140. If the supply voltage is

not generated by the PELV systems, other measures must be found that will

guarantee that live parts are safely separated.

WARNING

Use only temperature sensors with doubled or reinforced insulation according

to protection class II according to IEC 61140:2016 because there is no gal‐

vanic separation of the temperature sensor in the motor feedback system.

The power supply unit current used for the motor feedback system must be

limited to a maximum continuous current of 1 A, either by the power supply

unit itself or using a fuse.

NOTE

When configuring the switch-on current, observe
