Frequently Asked Questions - RU1113 IFM

How to connect the RU1113 encoder?

Connection is made via the IFM 15-pin male connector or a 5/13-wire cable. Follow the provided wiring diagram: L+ and 0 V wires for power supply, outputs A, B, index 0 and their inverted signals. Disconnect the installation from power before any connection.

What is the supply voltage of the RU1113?

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

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, provided appropriate cables are used.

How to interpret the output signals A and B?

Outputs A and B provide pulses phase-shifted by 90°. This phase shift allows determining the direction of rotation. The zero index emits one pulse per revolution for position reference.

How to mount the RU1113 encoder?

Attach the mounting flange (ref. E60033) to a base, then screw on the encoder. Connect the shaft via a flexible coupling to compensate for misalignments. Avoid shocks to the shaft.

What type of coupling to use?

Use a flexible bellows or elastic washer coupling to protect the encoder from excessive axial and radial forces.

What to do with unused wires during connection?

Unused wires must be individually insulated to avoid short circuits. Do not leave them in contact with other conductors.

What is the short-circuit protection?

5 V TTL version: outputs protected against short circuits to 0 V. HTL version: protected against short circuits to 0 V and L+ (max. 1 minute).

How to use the zero index?

The zero index provides one pulse per mechanical revolution. It serves as a position reference after a power outage. Can be used as a marker per revolution.

Where to find the datasheet and accessories?

The datasheet, additional documents and accessories (flanges, cables) are available on the website www.ifm.com.

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

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 100 m for the 5 V TTL version and 300 m 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.
