2. Safety and operating instructions
Supplementary information
•The present manual is intended as a supplement to already existing documentation (e.g. catalogues,
data sheets or mounting instructions).
•The manual must be studied carefully prior to initial commissioning of the equipment.
Intended purpose of the equipment
•The encoder is a precision sensing device. It is utilized to determine angular positions and revolutions,
and to prepare and supply measured values in the form of electrical output signals for the downstream
device. Encoders must not be used for any other purpose.
Commissioning
•The encoder must be initialised and mounted only by a qualified expert.
•Observe the operating instructions of the machine manufacturer.
Safety instructions
•Check all electrical connections prior to commissioning of the equipment.
•If mounting, electrical connections or any other work performed at the encoder and the equipment is not
correctly executed this can result in malfunction or failure of the encoder.
•Corresponding safety precautions must be provided and observed to exclude any risk of personal injury,
damage to material or operating equipment as a result of encoder failure or malfunction.
•Encoders must not be operated outside the specified limited values (see further documentation).
Failure to observe these safety instructions can result in malfunctions, material damage or personal injury.
Transport and storing
•Only ever transport or store the encoder in its original packaging.
•Never drop the encoder nor expose it to major shocks.
Mounting
•Avoid impacts or shocks on housing and shaft/end shaft.
•End shaft/Hollow shaft encoder: Open clamping ring completely before mounting the encoder
•Avoid any twist or torsion on the housing.
•Shaft encoders: never make rigid connections between encoder shaft and drive shaft.
•Do not open the encoder or proceed any mechanical modifications.
Shaft, ball bearings, glass disc or electronic components can be damaged thereby and a safe and reliable
operation is no longer ensured.
Electrical commissioning
•Do not proceed any electrical modifications at the encoder.
•Do not proceed any wiring work while encoder is live.
•Never plug or unplug connector while encoder is live (the bus cover however may be removed or docked
to the basic encoder when live).
•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. In case of earth loop problems, earth
at least on one side.
Failure to observe these instructions can result in malfunctions, material damage or personal injury!

3. Product family
The product family structure is modular. Depending on the requirements, basic encoder and bus covers can
be combined at will within the selected bus system. Basic encoders provide different specifications regarding
resolution, ambient conditions and sensing method.
Bus cover
The bus cover accommodates the fieldbus interface and the entire electronic circuitry for processing the
measured values. PROFINET communication is performed by the specific PROFINET-ASIC ERTEC200 with
integrated ARM9 high-performance micro-controller.
Magres / magtivo®
features a 12 bit resolution of 4096 steps per turn, applies a magnetic sensing method and withstands harsh
industrial environments.
Procoder / multivo®
features a 13 bit resolution of 8192 steps per turn, applies an optical/magnetic sensing method
and is the suitable product for standard applications.
Dignalizer / activo® / multivoPlus
features a 18 bit resolution of 262144 steps per turn, applies an optical/magnetic sensing method with
integrated analogue/digital conversion and is intended for ultra-precise sensing applications.
The basic encoder comprises a singleturn and a multiturn encoder. The multiturn encoder features a 16 bit
resolution respectively 65536 turns, or a 14 bit resolution corresponding to 16384 turns (multivoPlus). The
bus covers differ by their integrated bus interface. Available bus interfaces: CANopen, DeviceNet, EtherCAT,
Ethernet/IP, LIGHTBUS (fiber-optic), Profibus-DP, Profinet, Powerlink, Power over EtherCAT, SAE J1939,
SSI. Except for encoders with fiber-optic interface, all encoders enable parameterization by bus interface.

4. Commissioning
4.1. Mechanical mounting
Shaft encoders
•Mount the encoder by help of the mounting holes and three screws (square flange: 4 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.
End shaft/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.
•Mounting angle
Push the encoder onto the drive shaft. Insert adjusting angle into the encoder’s rubber buffer and fasten
the mounting angle at the contact surface.
•Stud screw
Push the encoder onto the drive shaft and insert the stud screw (customer-mounted) into the encoder’s
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.
4.2. Electrical connection
Ever store and transport the bus cover in the ESD bag only.
For electrical connection remove the bus cover as follows:
•Release the fastening screws of the bus cover
•Carefully loosen the bus cover and lift off in an axial direction
4.2.1. Cabling
PROFINET utilizes Fast Ethernet cable (100MBit, 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).

17.10.11
4.2.2. Connecting the bus cover
The bus cover provides three M12 connectors.
Two M12 connectors (D-coded, 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.
•Seal up the unused cable gland using a sealing bolt (included in the delivery).
There is no need to proceed any manual settings inside the bus cover. PROFINET does not require setting a
node ID and terminating resistor like Profibus. All address parameters are configured by the projecting tool
(e.g. Siemens®Step7®).

Assembly of basic encoder and bus cover:
•Carefully plug the bus cover onto the D-SUB connector of the basic encoder, then press it over the seal
taking care not to tilt it.
•Tighten both fastening screws firmly in the same direction.
•The bus cover must fully rest on the housing of the basic encoder and be firmly screwed on.
The encoder housing and braided shield of the connecting cable are only ideally connected if the bus cover is
resting fully on the basic encoder (positive locking).

5. Projecting
All examples in the present manual refer to SIEMENS®controls and the corresponding projecting tool Step7®
, since these are common PROFINET controls. With other controls please proceed in a corresponding way.
5.1. Importing the GSDML file
First the attached GSDML file must be imported to enable implementation of the encoder in the projecting
software. The file format is xml (“Extended Markup Language”). With reference to the Profibus GSD files,
GSDML is the common term.
The import operation is performed by Step7®software in the hardware window (HW Config, „Options – Install
GSD File…“). As a prior step the actual hardware project must be closed („Station - close“) to enable
successful import. Any alteration of basic settings are configured as described below. The GSDML file itself is
not modified.
In the following dialogue please select the directory including the GSDML file. Mark the file on screen. „Close”
will finalize the operation. The same directory also includes the corresponding Bitmap file providing a small
encoder image in the projecting tool. This file is automatically installed as well.
