Frequently Asked Questions - RN6020 IFM

How to wire the RN6020 encoder?

Before any wiring, de-energize the installation. Use a shielded cable and respect the wire colors indicated in the diagram. For example, the BN (brown) wire is for positive supply (+5V or +10-30V) and the WH (white) wire for 0V.

What is the difference between the 5V and 10-30V versions?

The 5V version provides a TTL output (6 mA) while the 10-30V version provides an HTL output (20 mA). The HTL version supports a longer cable length (100 m vs. 20 m).

How to choose the appropriate resolution?

The resolution (number of steps per revolution) depends on your precision needs. The RN6020 offers resolutions from 8 to 12 bits. A higher resolution (e.g., 12 bits = 4096 steps) provides better accuracy but reduces the maximum electrical speed.

Can I reverse the rotation direction of the encoder?

Yes, for 8 to 10 bit versions, the rotation direction can be selected via the MSB connection. Depending on whether you connect MSB to +5V or 0V, the rotation will be clockwise or counterclockwise.

What is the maximum rotation speed?

The maximum mechanical speed is 10,000 min⁻¹. The electrical speed depends on the resolution: 6000 min⁻¹ for ≤10 bits, 3000 min⁻¹ for 11 bits, 1500 min⁻¹ for 12 bits.

How to protect the encoder against short circuits?

The outputs are internally protected against short circuits between them and the supplies U_N or U_P for less than one minute. However, avoid prolonged short circuits.

What type of coupling to use for mounting?

It is recommended to use a flexible coupling between the encoder shaft and the motor to avoid damaging the shaft or bearings. Avoid jerks on the shaft.

How can I get the full manual in French?

The manual is available for free download in PDF format on notice-facile.com. You can also request a translation into your language by providing your email address.

Can the encoder be used outdoors?

The IP protection level is not specified in this manual. For outdoor use, check the protection rating in the full technical data sheet or contact IFM. In general, these encoders are designed for an industrial environment.

What to do in case of malfunction?

First check the electrical connections and the coupling. Make sure the power supply is correct and that the unlocking wires (A and B) are properly connected. If the problem persists, consult the manual or contact IFM technical support.

USER MANUAL RN6020 IFM

Function and features

The encoder converts rotary movements into digital numerical values. Each revolution is given as a numerical value. These values allow angular movements to be measured and positions to be determined.

• Supply voltage and number of steps according to the type label.
  Max. permissible mechanical: 10,000min
• Max. permissible electrical: 6000min^-1 ( ≤ 10bit ); 3000min^-1 (11bit); 1500min^-1 (12bit)
• The outputs are protected against a short circuit between the outputs and UN or UP for < 1 min.

Installation

Disconnect power. The drive must not be started during installation.

The encoder shaft must not be hit; do not use a file or a similar tool on the shaft, it could destroy the unit.

Encoder and drive should be connected by means of a flexible coupling in order to avoid damage to the shaft and the bearing.

In the case of linear measurement with rack and pinion the angle flange should be mounted on a resilient base. In the case of linear measurement with a measuring wheel encoder and measuring wheel should be mounted on the end of a flexible arm.

Electrical connection

Disconnect power before connection /disconnection of the cable or plug and socket connection.

Output signals:

• 5V version: TTL output, 6mA
• 10-30V version: HTL output 20mA, short-circuit protection

Extension by means of a screened extension cable; max. length 20m (5V version), 100m (10-30V version); lay separately from sources of interference (min. spacing approx. 20cm). Connect the encoder housing, the connector / terminal box and the evaluation electronics via the screen.

Pulse diagram

high-impedance signal outputs
- release A = low:

tracks 3 to 10 to output (8... 10bit version)

tracks 7 to 12 to output (11 and 12bit TTL version)

• release B = low:

tracks 1 to 2 to output (8 ... 10bit version)

tracks 1 to 6 to output (11 and 12bit TTL version)

• release A and release B simultaneously low:

tracks 1 to 8 (1 to 9; 1 to 10; 1 to 11; 1 to 12) to output

Release

When unused or at 0V the data are permanently present at the output. At high level the tracks are blocked.

MSB (change the direction of rotation)

For encoders with 8, 9 and 10 bits the direction of rotation can be selected via the connection:

connection MSB = clockwise rotation

connection MSB = anticlockwise rotation
