Frequently Asked Questions - RU1114 IFM

What type of power supply is required for the RU1114?

The RU1114 is available in two versions: 5 V TTL or 10...30 V HTL. Check the label on the housing to know the version.

How to connect the RU1114 encoder?

Disconnect power. Use a suitable cable or connector (male base ifm1000.xx or ifm1001.xx). Follow the wiring diagram provided on the housing cover. Insulate unused wires.

What are the output signals of the RU1114?

The encoder delivers pulse sequences on outputs A and B, phase-shifted by 90° to determine the direction of rotation. A zero index is provided once per revolution. Inverted outputs (A neg., B neg., index neg.) are available for differential transmission.

What is the maximum cable length?

For the 5 V TTL version, the maximum length is 100 m. For the 10...30 V HTL version, it is 300 m. Use shielded cables and install them at least 20 cm away from interference sources.

How to mount the RU1114?

Screw the encoder onto a mounting flange (ref. E60033). Connect the shaft via a flexible bellows or elastic disk coupling to compensate for misalignment. Avoid impacts on the shaft.

Can linear displacements be measured with this encoder?

Yes, by using a measuring wheel or rack and pinion to convert linear motion to rotation. Observe the maximum shaft loads.

What to do in case of a short circuit?

The outputs are short-circuit protected. For the HTL version, protection is active on 0 V and L+ for max. 1 minute. After that, disconnect power and check the wiring.

How to clean the RU1114?

Clean the housing with a dry, non-abrasive cloth. Do not use files or tools on the shaft to avoid damaging the device.

Where to find accessories or spare parts?

Check the website www.ifm.com for datasheets, accessories (flanges, cables, connectors) and other documents.

What to do if the device does not work?

Check the wiring, power supply and signal integrity. If the problem persists, contact IFM support. The encoder is not user-repairable.

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.
