1.Introduction

1.1 About This Manual

This technical manual describes the conguration and mounting possibilities for absolute-value encoders with a PROFINET interface produced by

Encoder Products Company (EPC). It supplements the other publicly available EPC documents, e.g. data sheets, assembly instructions, leaets,

catalogues and yers.

Ensure that you read the manual before provisioning — check beforehand that you have the latest version of the manual.

When reading, pay particular attention to the information, important notices and warnings that are marked with the corresponding symbols (see

1.1.1).

This manual is intended for persons with technical knowledge in the handling of sensors, PROFINET IRT interfaces and automation elements. If you

do not have any experience in this eld, request the assistance of experienced personnel before proceeding.

Keep the information provided with our product in a safe place so that you can refer to it at a later date as necessary.

The contents of this manual are arranged with practical use in mind.

All of the information in the following sections is required to get the best possible use out of the equipment, and should be

read through thoroughly.

1.1.1 Explanation of Symbols Used in this Manual

The INFO symbol is placed next to a section of text that is particularly informative or important for what to do next with

the equipment.

The IMPORTANT symbol is placed next to a section of text in which a process is described to resolve a particular problem.

1.2 Products Supported

This manual supports the following types of EPC Absolute Encoders:

• Model A58HE – PROFINET absolute hollow-bore encoder with bus cover

• Model A58SE – PROFINET absolute shaft encoder, synchro or clamping ange, heavy-duty or compact, with bus cover

EPC's PROFINET product range can be found on our website: encoder.com/pronet

1.3 Specications

An encoder is a sensor that is designed to detect angular positions (single-turn) and revolutions (multi-turn).The measured data and variables are

processed by the encoder and provided as electrical output signals for the connected peripherals.

Patented technologies for single-turn and for multi-turn are used in the A58SE and A58HE series encoders. As a result, these encoders from EPC are

maintenance-free and very eco-friendly.

The encoders whose article descriptions are listed in Section 1.2 communicate via the PROFINET IRT interface.

1.4 Scope of Delivery

The scope of delivery depends on the product variants and the details of your order. Before commissioning, check the contents of the delivery for

completeness.

As a rule, the A58HE and A58SE products have a PROFINET IRT interface includes the following items:

• A58HE or A58SE with PROFINET-IRT (with bus cover)

• Assembly instructions

2.Safety Information

2.1 General

• When provisioning the encoder, ensure that you observe the assembly instructions, manual and data sheet.

• Failure to observe the safety instructions may lead to malfunctions, property damage and personal injury!

• Observe the operating instructions provided by the machine's manufacturer.

2.2 Intended Use

Rotary encoders are components that are intended for installation in machines. Before commissioning (operation in accordance with the intended

use), it must be determined that the machine as a whole corresponds to the EMC and Machine Directive.

A rotary encoder is a sensor that is designed to detect angular positions and revolutions and must only be used for this purpose! EPC Automation

manufactures and distributes encoders for use in non-safety-relevant industrial applications.

The encoder must not be operated outside the specied limit parameters (see product datasheet).

2.3 Safe Working

The installation and mounting of the encoder must only be carried out by a qualied electrician.

For the construction of electrical installations, all relevant national and international regulations must be strictly observed.

Failure to commission the encoder correctly may result in malfunction or failure.

• All electrical connections must be tested before commissioning.

• Appropriate safety measures must be taken to ensure that no persons are harmed and no damage to the system or operating equipment

occurs in the event of a failure or malfunction.

2.4 Disposal

Devices that are no longer needed or are defective must be disposed by the user in proper compliance with the country-specic laws. It must be

taken into consideration that this is a special waste of electronics and that disposal is not permitted via normal household waste.

There is no obligation by the manufacturer to take the device back. If you have any questions regarding proper disposal, contact a disposal specialist

in your area.

3.Device Description

3.1 General

Various mechanical variants of the A58SE and A58HE-series encoders with PROFINET-IRT are available. The required variant is determined by the

need for a bus cover, the ange design and the shaft type (solid or hollow).The size is specied as 58 mm by the diameter at the ange.The follow-

ing gure shows examples of A58SE/HE-series encoders with PROFINET IRT.

The solid or hollow shaft is connected to the rotating component whose angular position or rotational speed is to be measured. Cable or plug

outlets create the interface for connection to the PROFINET network.The status LEDs mounted in the cover signal the various encoder states during

operation.They assist with conguration of the encoder and troubleshooting in the eld.The ange holes or supplied spring sheets are used for

attachment to the machine and during the respective application.

3.2 PROFINET

PROFINET is distributed by the PROFIBUS User Organization (PNO) as a successor to Probus. PROFINET is the standard interface for industrial Ether-

net. PROFINET provides similar functionality to Probus, but extends these by rmware upgrades.

Established IT standards are used for the transfer of information. UDP, IP and XML form the basis for this. XML is used as a description language

in the device prole (abbreviated to "GSDML le"). In order for the devices to exchange their data via IP — process data (cyclic) and parameter data

(acyclic) — a unique name must be assigned to each PROFINET node during conguration.The control can only assign an IP address to the node via

this name.

PROFINET supports the following three transmission types:

• PROFINET NRT (not real time), non-time-critical applications in automation, clock rates of around 100 milliseconds.

• PROFINET RT (real time), cyclic data trac is used to achieve clock rates of 10 milliseconds.

• PROFINET IRT (isochronous real time), clock rates of 1 millisecond and jitter of less than 1 microsecond.This is suitable for use in motion-

control applications (for example).

Further information about PROFINET is available via the homepage of the PROFIBUS User Organization (PNO) at: https://www.probus.
