2. Safety and operating instructions
Intended use
The encoder is a precision measuring device that is used to record positions and speeds. It provides
measuring values as electronic output signals for the subsequently connected device. It must not be used
for any other purpose. Unless this product is specially labeled, it may not be used for operation in
potentially explosive environments.
Make sure by appropriate safety measures, that in case of error or failure of the encoder, no danger to
persons or damage to the system or operating facilities occurs.
Personnel qualification
Installation and assembly of this product may be performed only by a person qualified in electronics and
precision mechanics.
Maintenance
The encoder is maintenance-free and must not be opened up nor mechanically or electronically modified.
Opening up the encoder can lead to injury.
Disposal
The encoder contains electronic components. At its disposal, local environmental guidelines must be
followed.
Mounting
Solid shaft: Do not connect encoder shaft and drive shaft rigidly. Connect drive and encoder shaft with a
suitable coupling.
Hollow shaft: Open clamping ring completely before mounting the encoder. Foreign objects must be kept
at a sufficient distance from the stator coupling. The stator coupling is not allowed to have any contact to
the encoder or the machine except at the mounting points.
Electrical commissioning
Do not proceed any electrical modifications at the encoder.
Do not proceed any wiring work while encoder is live.
Do not remove or plug on connector whilst under power supply.
Ensure that the entire system is installed in line with EMC/EMI requirements. Operating environment and
wiring have an impact on the electromagnetic compatibility of the encoder. Install encoder and supply
cables separately or far away from sources with high emitted interference (frequency converters,
contactors, etc.).
When working with consumers with high emitted interference provide separate encoder supply voltage.
Completely shield encoder housing and connecting cables.
Connect encoder to protective earth (PE) using shielded cables. The braided shield must be connected to
the cable gland or connector. Ideally, aim at dual connection to protective earth (PE), i.e. housing by
mechanical assembly and cable shield by the downstream devices.
Supplementary information
The present manual is intended as a supplement to already existing documentation (e.g. catalogues, data
sheets or mounting instructions).

10.22
3. Commissioning
3.1. Mechanical mounting
Shaft encoders
Mount the encoder by help of the mounting holes and three screws provided at the encoder flange.
Observe thread diameter and depth.
There is an alternative mounting option in any angular position by eccentric fixings, see under
accessories.
Connect drive shaft and encoder shaft by using an appropriate coupling. The shaft ends must not touch
each other. The coupling must compensate temperature and mechanical tolerances. Observe the
maximum permitted axial or radial shaft load. For appropriate couplings please refer to accessories.
Tighten the mounting screws firmly.
Hollow shaft encoders
Mounting by clamping ring
Prior to mounting the encoder open the clamping ring completely. Push encoder onto the drive shaft and
tighten the clamping ring firmly.
Adjusting element with rubber buffer
Push the encoder onto the drive shaft and insert the cylindrical pin into the adjusting element (customer-
mounted) and the rubber buffer.
Spring washer
Fasten the spring washer at the mounting holes of the encoder housing using screws. Push the encoder
onto the drive shaft and mount the spring washer to the contact surface.
3.2. Electrical connection
3.2.1. Cabling
PROFINET utilizes Fast Ethernet cable (100 MBit, Cat 5) composed of four wires AWG22 (white, yellow,
blue and orange).
There are three types of PROFINET cables:
Type A –for fix or rigid cabling
Type B –for occasional movements or vibrations (flexible)
Type C –for permanent movements (highly flexible).

Baumer_EAx_PROFINET_EN_202210_MNL.docx 10/74 www.baumer.com
10.22
3.2.2. Connecting
The encoder provides three M12 flange connectors.
Two M12 flange connectors (D-coding, according IEC 61076-2-101) serve for PROFINET connection.
For voltage supply use A-coded M12 connector only.
For the bus lines both D-coded M12 connectors may be used at will. However, together with a planned
topology it may be necessary to observe the correct assignment (P1/P2).
Seal up the unused cable gland using a sealing bolt (transport and dust protection).
No settings have to be done inside the encoder. In contrast to Profibus, there is no need for setting a node
ID or a terminating resistor. All settings required for encoder access are made in the engineering tool (e. g.
Siemens®Step7®or TIA®Portal).

3.2.3. Push Button for Preset / Reset
Depending on encoder the type the encoder may have a screw cap located where connectors and LEDs are
located as well. After removing the screw cap, the preset / reset push button is visible.
Depending on the current operating state the push button has a different functionality:
In the first 60 seconds after switching on the encoder the encoder performs a “Factory Reset“.
oUp to firmware version 1.2.x this only works if the encoder has no Ethernet connection.
oSince firmware version 1.3.0 this works with and without an Ethernet connection.
With active PROFINET operation the encoder performs a preset.
Note:
After having used the push button the screw cap must be screwed in again and tightened with a torque of 1.5
Nm.
For functionality details see 0 „
The preset value can be set to a value unequal 0. To do this no program, PLC function block or similar things
are necessary. If one of the PROFIdrive telegrams 81 to 83 is used and a preset is triggered (in operation)
the value in PNU 65000 is used as preset value.
This functionality is for example very useful if the desired preset value does not change during operation.
Preset using the Push Button“or 4.9 „Restore Factory Defaults“, respectively.

4. Engineering (Siemens® Step7®)
The following examples relate to SIEMENS®PLCs using the engineering tool SIEMENS®Step7®. The
screenshots were taken from Step7®V5.5 SP3. Engineering with TIA Portal®is described in chapter 5. Of
course, the encoder will also accept engineering software of other manufacturers - in this case, proceed in
an analog way.
4.1. Importing the GSDML file
First, the GSDML file must be imported to enable implementation of the encoder in the engineering tool. The
file format is XML (“Extended Markup Language”). With reference to the Profibus GSD files, GSDML is the
common term.
The GSDML file is available for download at www.baumer.com.
Use this GSDML file:
GSDML-V2.32-Baumer-EAx580_PN-20170112.xml
for encoders with firmware V1.2.2 or later
GSDML-V2.32-Baumer-EAx580_PN-20190715.xml
for encoders with firmware V1.3.0 or later
Relevant difference of GSDML files:
From GSDML file «GSDML-V2.32-Baumer-EAx580_PN-20190715.xml“ onwards the usage of the
functionality “setting of the preset value (PNU 65000) in the module parameters“ is possible.
The revision can be seen in the date at the end of the file name. Here it has to be seen as an example.
The date has to be read in the format “YYYYMMDD” (Y: year, M: month, D: day). In the example above
the date is January 12th 2017.
The import operation is performed by Step7®software in the hardware window („HW Config” - „Options –
Install GSD File…“). As a prior step it may be necessary to close the actual hardware project („Station -
close“) to enable successful import. Based on the default settings any change is configured as described
below. The GSDML file itself is not modified.
In the following dialogue please select the directory where to find the GSDML file which shall be installed.
It is useful (but not necessary) to work with the program directory „…\Siemens\Step7®\S7Tmp“.
The file is displayed and can be selected. „Close” will finalize the operation. The same directory also includes
the corresponding bitmap file providing a small encoder image in the engineering tool. This file is
automatically installed in parallel.

Baumer_EAx_PROFINET_EN_202210_MNL.docx 13/74 www.baumer.com
10.22
The encoder now appears in the hardware catalog under „PROFINET IO“ – „Additional Field Devices“ –
„Encoders“ – „Baumer PROFINET Encoder“ - “EAx PROFINET Encoder “ – „EAx580…“ (x according to
encoder type).

Baumer_EAx_PROFINET_EN_202210_MNL.docx 14/74 www.baumer.com
10.22
4.2. Encoder integration into the project
Use the mouse to drag the basic module „EAx580 encoder“ from hardware catalog to bus rail.
In the next step, select the encoder module (for example "EAL580 MT encoder ST13 MT16 optical") and
drag from hardware catalog for drop in subslot 1.2 (bottom left) in the hardware window.
In the next step, select and drag the desired I/O telegram (e.g. telegram „860“) for drop in subslot 1.2.
4.3. Assigning the device name
Device identification in the network requires the worldwide unique MAC ID, the (statically or dynamically
assigned) IP address and third a unique device name in the PROFINET network. All three identifiers are
used during system bootup and during operation. Thus, engineering requires to assign the encoder’s device
name.
4.3.1. Setting the device name in the Project
Double-click on the encoder symbol in HW Config. window. The properties window opens with an input field
to enter the desired device name.
4.3.2. Automatic Name Assignment
The device name can be written automatically into the encoder. In the factory-provided state and after a
“factory reset” the device name in the encoder is empty.
Preconditions for automated name allocation:
A topology planning has been defined.
The previous device name has been deleted (e. g. by “factory reset”).
Option „Support device replacement without exchangeable medium“ (see following screenshot) is
enabled.
Automated name allocation is executed as soon as the encoder logs on the network where projected.

Baumer_EAx_PROFINET_EN_202210_MNL.docx 15/74 www.baumer.com
10.22
4.3.3. User-operated name assignment
To perform an I/O system network scan, go to „PLC“ –„Edit Ethernet Node“ –„Browse“. The scan provides
all bus nodes. In the example the encoder „encoder01“was found.
The MAC address ensures unique device recognition. Button „flash“ will start the identified user‘s SF LED
flashing for clear identification.
A double-click on the desired line (here: encoder “encoder01”) opens the window “Edit Ethernet Node”.
Enter the new name required for configuration in line “Device name“. Click “Assign name” to execute. After
this, the encoder will immediately be recognized with this name in the PROFINET network.

Baumer_EAx_PROFINET_EN_202210_MNL.docx 16/74 www.baumer.com
10.22
Notes:
- It is not possible to set the device name via the MPI interface.
- When specific device data (for example the station name) is written, the power supply may not be
switched off.

10.22
4.4. Real-Time Class Selection
The PROFINET encoder supports both real-time classes “Real-Time”(RT) and “Isochrone Real-Time”(IRT)
Class 3. Which one to use depends on the application and the PLC.
4.4.1. Domain Management
The Domain Management determines the PROFINET bus properties.
Enter the Domain Management by right-clicking the PROFINET bus rail in the hardware window.
In the following screen „Domain Management“ enter the „Sync domain”name or keep the default.
For IRT Class 3 only enter the send clock here.
For RT Class 1 open the property window of the PLC‘s PROFINET port (e. g. X2), see chapter 5.4.2.2.
The send clock applies to the IO Controller and to all IO Devices within this sync domain and is decisive for
the overall system performance.

Baumer_EAx_PROFINET_EN_202210_MNL.docx 18/74 www.baumer.com
10.22
4.4.2. Real-Time (RT) Class 1
In this class a typical cycle time of 100 ms or less is possible. The bus system allows for standard Ethernet
components.
Topology planning is not mandatory, but where implemented (e. g. for retrieving feature „Support device
replacement without exchangeable medium”), make sure ports P1/P2 are correctly assigned as planned.
4.4.2.1. Address assignment within the process image
Access to the encoder’s input and output data takes place via addresses within the PLC’s process image.
Assign these addresses according to the needs of the PLC software.
Go to the Step7®HW Config. window and click on the encoder symbol on the bus rail to select it. Bottom left
in the module window the various encoder modules are shown. A double click on submodule 1.2 (e. g.
"telegram 860") opens the property window with tab „addresses“.
Enter the start address of the respective address range or accept the system’s proposal. Identical or
overlapping addresses for input and output are possible.
The process image (PI) will be that of the cyclic main program OB1 (not synchronized).

Baumer_EAx_PROFINET_EN_202210_MNL.docx 19/74 www.baumer.com
10.22
4.4.2.2. Synchronization Setup
Go to the Step7®HW Config. window and click on the encoder symbol on the bus rail to select it. Bottom left
in the module window the various encoder modules are shown. Enter the interface properties with a double
click on the „Interface“ module.
The „Synchronization“ tab shows the assignment to a certain sync domain. Real-Time (RT) Class 1 mode is
„not synchronized“. Set the synchronization role accordingly.
Go to „RT class“ to select „RT (Class 1)“or „IRT“. „IRT Option“ is pre-assigned to „high performance“ (IRT
Class 3) which requires corresponding PLC configuration.
Properties Tab „IO Cycle“, area „Update Time“ offers settings for the requested update time. In relation to the
send clock a reduction ratio „factor“ applies. In case of a reduction ratio the encoder will not update and send
its position value each send clock cycle, but only every 2nd, 4th or 8th cycle. Not every application needs
being updated at the high send clock rate. At a high bus load this reduction may save bandwidth. Applicable
factors may vary with the real-time class and send clock and are offered in the drop down area.

4.4.3. Isochronous Real-Time (IRT) Class 3
Isochronous real-time considering signal delays
Typical cycle time: 1 ms or less
A topology planning is mandatory. Make sure ports P1/P2 at the encoder are correctly assigned as planned.
