Frequently Asked Questions - RO6339 IFM

How to connect the RO6339 encoder?

Cut off power before any connection. Connect according to the diagram: L+ (brown/green), 0V (white/green), outputs A, B, index, etc. Unused wires must be insulated.

What is the supply voltage of the RO6339?

The encoder is available in 5 V TTL or 10...30 V HTL version depending on the model. Check the housing label.

What are the output signals?

The outputs are A, B and index (zero). Inverted signals (A neg., B neg., index neg.) are also available for differential transmission.

What is the maximum cable length?

The maximum 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 protect the encoder against short circuits?

The outputs are protected against short circuits: on 0V for the TTL version, on 0V and L+ for the HTL version (max. 1 minute).

How to mount the encoder on a shaft?

Put the clamping nut on the encoder, insert the shaft at least 10 mm, fix the stator coupling with four M3 screws, then tighten the nut.

What to do if the encoder is damaged?

Repairs must be carried out by the manufacturer. Do not open the housing.

How to interpret the A and B signals?

The A and B signals are phase shifted by 90° electrically. The direction of rotation is determined by the order of the pulses: A leading or lagging B.

What is the zero index?

The zero index is a single pulse per mechanical revolution. It serves as a position reference, for example after a power failure.

Where to find the datasheet of the RO6339?

You can download it from www.ifm.com. Other documents and accessories are available there.

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

Standard wiring:

	Flange plug 13-wire cable 12-pole
L+ M brown/green
L+ sensor B blue
0V K white/green
0V sensor L white
A E brown
A neg. F	green
B	H	grey
B neg. A	pink
0 index	C	red
0 index neg.	D	black
fault neg.	G lilac
free	-	-
free	-	yellow
screen	housing	housing

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

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!

Continuous hollow shaft

1. Place the clamping nut on the encoder.
2. Slip the encoder onto the shaft (min. 10mm ) and fix the stator coupling by means of four M3 screws.
3. Tighten the screws of the clamping nut.

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.
