When mounting the encoder on a mechanical frame (bell, bracket...):

Use at least 3 M3 or 3 M4 screws for a safe assembly.

Minimal screwing depth 5mm for M3 and 6mm for M4.

Use at least 3 M6 screws for a safe assembly.

Minimal screw depth is 10mm.

Before mounting on the driving shaft, check the shaft alignment to avoid compressing or extending the coupling device.

Encoder’s solid shafts are machined with a key slot. Use a keyed coupling to secure the rotation transmission.

Tighten with the recommended torque from the coupling manufacturer.

Up to 100m cable.

Up to 100m cable.

With cables lengths

longer than 20m, a

“GP” cable/wiring

type is recommended

in conjunction with a

Up to 100m cable

with frequency

restrictions.

Consult the “Safety

User Manual” for

detailed information.

ELECTRICAL MOUNTING PROCEDURE

Verify that all electrical devices are switched off before starting the installation and that you have

the mandatory power supply.

Check that you have all the necessary information on wiring connections: refer to the encoder

sticker for pin out and/or wire color signal correspondence.

Ensure the electrical connection is in accordance with the standard recommendations governing the

use of cables/connectors.

To avoid possible non valid signal detection during the encoder initialization time, the operating power

supply voltage of the encoder and of the controller should be switched on and off simultaneously.

• Respect the cable bending radius.

• Protect the cables to avoid a cut or damage during operation.

• Always provide a service loop between encoder and the first

cable clamp to avoid cable tension.

• Never operate with a cable which is totally or partially coiled.

• Never connect outputs together or to a potential.

• In case signals Z and Z/ are not used in the application, connect each of them

with 3kohms pull down resistors to 0V.

• Never use the same cable for driving power (motor power supply, variable

frequency drive, etc.) and encoder signals.

• Separate encoder cables and potentially interfering signal cables with a metal

screen grounded and do not let them run parallel.

• If a metallic connector is assembled by the user on the encoder cable, ensure

a 360° shield contact on that connector.

• When using a shielded pair cable, always connect signals of the same

channel to the same twisted pair: A with A/, B with B/ and Z with Z/.

• Ensure that encoder’s body and cable shield extremity are both connected to

same potential grounds.

• Do not cut nor leave the ground plant unconnected.

• In the cabinet, connect the encoder cable surrounding screen to the ground

plant if available, otherwise to the 0V.

• To avoid destructive electrostatic discharging shaft phenomena, always

ground the encoder housing.
