Frequently Asked Questions - RO6305 IFM

How to connect the RO6305 encoder?

Disconnect the installation from power. Use the 12-pole male connector following the provided wiring diagram (see housing cover). Insulate unused wires to avoid short circuits.

What supply voltage to use?

The encoder operates at 5 V TTL or 10...30 V HTL depending on the version. Check the housing label.

What to do if outputs are short-circuited?

Outputs are protected against short circuits. For HTL version, protection is active for max. 1 minute. Disconnect power and check wiring.

How to mount the encoder on a shaft?

Slide the encoder onto the shaft (at least 10 mm). Secure the stator coupling with four M3 screws (torque 1 Nm). Tighten the clamping nut (torque 1.1 Nm). Avoid impacts on the shaft.

What is the maximum cable length?

100 m for 5 V TTL version and 300 m for 10...30 V HTL version, with appropriate cables installed at least 20 cm from interference sources.

What are the output signals?

Outputs are A, B and index 0, each with its inverted signal. Outputs A and B are 90° out of phase to determine rotation direction. The zero index is output once per revolution.

How to determine the rotation direction?

The 90° phase shift between outputs A and B allows the rotation direction to be evaluated in the electronic module.

What does the zero index mean?

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

How to protect the encoder against interference?

Install cables at least 20 cm away from interference sources. Use shielded cables; the braided shield is connected to the encoder housing.

Where to find the datasheet and accessories?

On the website www.ifm.com. You will find the datasheet, additional documents, and suitable accessories.

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 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!

1. Place the clamping nut on the encoder.
2. Slip the encoder onto the shaft (min. 10 mm) 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.
