2 Safety instructions

• The device described is a subcomponent for integration into a system�

- The manufacturer is responsible for the safety of the system�

- The system manufacturer undertakes to perform a risk assessment and to

create a documentation in accordance with legal and normative requirements

to be provided to the operator and user of the system� This documentation

must contain all necessary information and safety instructions for the operator,

the user and, if applicable, for any service personnel authorised by the

manufacturer of the system�

• Read this document before setting up the product and keep it during the entire

service life�

• The product must be suitable for the corresponding applications and

environmental conditions without any restrictions�

• Only use the product for its intended purpose (→ 3 Functions and features).

• If the operating instructions or the technical data are not adhered to, personal

injury and/or damage to property may occur�

• The manufacturer assumes no liability or warranty for any consequences

caused by tampering with the product or incorrect use by the operator�

• Installation, electrical connection, set-up, programming, configuration, operation

and maintenance of the product must be carried out by personnel qualified and

authorised for the respective activity�

• Protect units and cables against damage�

3 Functions and features

The encoder converts rotary movements into digital numerical values� Each

angular position of the revolutions is provided as a numerical value�

These values allow angular movements to be measured and positions to be

determined�

Because of the requirements for electromagnetic interference emissions, the

device is intended for use in industrial environments� The device is not suitable for

use in domestic areas�

4 Installation

►Disconnect power�

►Ensure that the machine stands still�

►The drive must not be started during installation�

►Do not hit the shaft; do not use a file or similar tool on the shaft: risk of

destruction�

► Keep potential interfering sources (magnets, heat sources etc.) at a distance.

This product is a precision measuring device� Therefore it has to be handled with

care by trained staff� The following warnings apply to influences outside the limit

values indicated in the product data sheet�

Damage to the product can be caused by:

• too high forces on the shaft

• humidity and chemical liquids (do not connect any cables oriented upwards)

• extreme temperatures

• too high vibrations and shocks

• short circuit or too high an operating voltage

• impact, shock or any other physical forces

2: Coupling

►Minimise the displacement between the two shafts�

►Avoid the following mistakes:

- radial displacement

- angular displacement

- axial movement

►To minimise the forces on the shaft use a flexible shaft coupling with guiding

slot for the installation�

4.1.3 Type with hollow shaft

Version with one stator coupling Version with two stator couplings

1: Angle bracket

►Verify the radial displacement after installation and with slow rotation�

The displacement must not be larger than 0�5 mm since otherwise the life cycle of

the encoder may be shortened or the system accuracy impaired�

5 Electrical connection

►Disconnect power�

►Connect the IO-Link device via the M12 socket to an IO-Link master�

(18…30 V DC PELV; according to DIN EN50178, secondary circuit with maximum

30 V DC).

- Tightening torque: 0�6��0�8 Nm

- Recommended maximum cable length: according to IO-Link specification 1�1�3

►To connect the device, use M12 connectors with protection rating IP 65 / IP 66 /

IP 67 or higher�

6 Function

6.1 IO-Link

This unit has an IO-Link communication interface which enables direct access to

process and diagnostic data� In addition it is possible to set the parameters of the

unit while it is in operation� Operation of the unit via the IO-Link interface requires

an IO-Link master�

With a PC, suitable IO-Link software and an IO-Link adapter cable, communication

is possible while the system is not in operation�

The IODDs necessary for the configuration of the unit, detailed information about

process data structure, diagnostic information, parameter addresses and the

necessary information about the required IO-Link hardware and software can be

found at www�ifm�com�

The IO-Link interface provides the following (additional) functions using suitable

hardware and software:

• Remote parameter setting of the unit�

• Noise-immune signal transmission without measured value losses�

• Transmission of the parameter settings to a replaced sensor or to other

sensors of the same type�

• Simultaneous reading of all process values and the binary switching signals�

• Comprehensive display of error and event messages�

• Management of device tags�

• Evaluation of the process values and diagnostic data via IO-Link master�

• Paperless logging of parameter sets, process values and diagnostic information

6.2 Switching function rotational speed

SSC2�x changes its switching state if it is above or below the set switching limits

(SP1, SP2).

First set the set point (SP1), then the reset point (SP2).

The resulting hysteresis remains even if SP1 is changed again�

• Window function / normally open: [SSC2�x] = [Fno]

• Window function / normally closed: [SSC2�x] = [Fnc]

The width of the window [FE] can be set by means of the difference between

SSC2�1 and SSC2�2�

SP1 = upper value, SP2 = lower value�

7 Parameter setting

Parameters can be set before installation and set-up of the unit or during operation

via the IO-Link interface�

If parameters are changed during operation, this will influence the function

of the plant�

►Ensure that there will be no malfunctions in your plant�

During parameter setting the unit remains in the operating mode� It continues

to monitor with the existing parameter until the parameter setting has been

completed�

►Connect the unit to a parameter setting software via suitable hardware�

►Set the parameters�
