Frequently Asked Questions - RU1085 IFM

How to connect the RU1085 encoder?

Turn off the installation. Connect the wires according to the wiring diagram provided on the housing cover or in the manual. Unused wires must be insulated to avoid short circuits.

What supply voltage to use?

The encoder is available in two versions: 5 V TTL (outputs protected on 0 V) or 10…30 V HTL (outputs protected on 0 V and L+). Check the housing label for the version.

What to do with the L+ sensor and 0 V sensor wires?

These wires are internally connected to the supply voltage. If you use voltage-regulating electronic modules, they can serve as test wires. Otherwise, they must be connected to the power supply or insulated.

What is the short-circuit protection?

In the 5 V TTL version, outputs are protected against short circuits on 0 V. In the HTL version, they are protected on 0 V and L+ (max. 1 minute).

What is the maximum allowed cable length?

The maximum cable length is 100 m for the 5 V TTL version and 300 m for the 10…30 V HTL version, with appropriate cables.

How to mount the RU1085 encoder?

Screw the encoder onto a fixing flange (ref. E60033). Connect the shaft via a flexible bellows or elastic washer coupling to compensate for misalignments. Avoid shocks to the shaft.

What accessories are available?

Accessories, such as the fixing flange E60033, are listed on the website www.ifm.com. You will also find the datasheet and other documents there.

How to interpret the output signals?

Outputs A and B are phase-shifted by 90° to determine the direction of rotation. The zero index is emitted once per mechanical revolution. The inverted signals are used for differential input.

How to protect the encoder from interference?

Install the cables separately from interference sources with a minimum distance of 20 cm. The braided shield is connected to the encoder housing.

What to do in case of encoder failure?

Contact IFM after-sales service. The complete manual and support information are available at www.ifm.com.

USER MANUAL RU1085 IFM

Function and features

The encoder transforms rotational movement into pulse sequences. These allow the measurement of linear distances and angular movement as well as the determination of positions.

Electrical connection

Disconnect power from the installation before connecting or disconnecting cables or connectors!

Unused wires must be insulated to avoid short circuits and cross faults.

Short-circuit protection

5 V TTL version: outputs short-circuit protected against 0 V 10...30 V HTL version: outputs short-circuit protected against 0 V and L+ for maximum 1 minute

Wiring is also indicated on the housing cap. If there is a deviation, the encoder must be connected as indicated on the label on the housing cap.

The wires L + (sensor) and 0V (sensor) are internally connected to the supply voltage. When using external electronics which regulate the supply voltage these wires can be used as test wires. If unused, these wires must be connected to the supply voltage or insulated.

Depending on the version, the electrical connection is made via the cable or via cables to be obtained separately.

When using suitable cables the maximum cable length is 100m for the 5 V TTL version and 300m for the 10...30 V HTL version.

The cables must be laid separately from interfering sources, the minimum distance is 20~cm .

The braided screen in the cable is connected to the encoder housing.

Output signals

output A

output B

0 index

The encoder provides digital pulse sequences at the output stages. The outputs A and B are electrically offset by 90^ . Thus the direction of rotation can be evaluated in the external electronics.

The combined zero index is provided once in a mechanical revolution of the shaft. In case of power failure it can be used as a reference point within a revolution.

The inverted output signals are used for external electronics with differential voltage input to filter interference.

Installation

Do not hit the shaft, do not use a file or similar tool on the shaft: This could destroy the unit!

The encoder can be screwed to the angle bracket. The shaft should be connected using a flexible bellows or spring disc coupling to compensate for shaft displacement and to protect the encoder against damage.

Linear movements can be transformed into a rotational movement using a measuring wheel or rack and pinion. For mounting the maximum permissible shaft loads of the encoder must be taken into account.

Mounting the angle bracket on a resilient base protects the encoder against too high a stress due to roughness of the material.
