Frequently Asked Questions - RU1189 IFM

How to connect the IFM RU1189 incremental encoder?

Before any connection, disconnect the power. Use the wiring diagram provided on the housing cover. Unused wires must be insulated. For 5 V TTL versions, observe a maximum cable length of 100 m; for HTL versions, 300 m.

What types of output signals does the encoder provide?

The encoder provides digital signals on outputs A and B, phase-shifted by 90° to determine direction of rotation, as well as a zero index once per revolution. Inverted signals are available for differential inputs.

What is the supply voltage of the RU1189?

The encoder is available in two versions: 5 V TTL and 10…30 V HTL. Check the housing label for the exact version.

How to protect the encoder against short circuits?

The outputs are short-circuit protected: 5 V TTL version to 0 V; HTL version to 0 V and L+ (max. 1 minute). Also ensure to insulate unused wires.

What is the maximum usable cable length?

100 m for the 5 V TTL version and 300 m for the 10…30 V HTL version, provided that appropriate cables are used and kept away from interference sources (minimum distance 20 cm).

How to mount the encoder on a shaft?

Fix the encoder on a mounting flange and connect the shaft via a flexible bellows coupling or elastic washer to compensate for misalignment. Avoid shocks to the shaft.

How to clean the encoder?

Clean the exterior with a dry cloth. Do not use aggressive solvents or abrasive tools that could damage the housing.

What to do in case of malfunction?

First check the electrical connection and supply voltage. If the problem persists, contact IFM customer service or an authorized technician. Do not attempt to repair the device yourself.

What accessories are available for the RU1189?

Connection cables (5 or 13 wires), connectors, a mounting flange (ref. E60033), flexible couplings and measuring wheels to convert linear displacements.

Where to find the complete manual and datasheet?

The manual is available free of charge in PDF format on sites like notice-facile.com. The datasheet and accessories are available on the IFM 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 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.
