Connection Motor Encoder (CN3)

Function and Encoder Type

The motor encoder is a Hiperface encoder integrated in the motor. It provides the device with information on the motor position (analog and digital).

Cable Specifications

Shield:	Required, both ends grounded
Twisted Pair:	Required
PELV:	Required
Cable composition:	6 * 0.14 mm² + 2 * 0.34 mm² (6 * AWG 24 + 2 * AWG 20)
Maximum cable length:	100 m (328.08 ft)

Use pre-assembled cables to reduce the risk of wiring errors, see chapter Accessories and Spare Parts.

WARNING

UNINTENDED EQUIPMENT OPERATION

Do not connect any wiring to reserved, unused connections, or to connections designated as No Connection (N.C.).

Failure to follow these instructions can result in death, serious injury, or equipment damage.

Connecting the Motor Encoder

oVerify that wiring, cables and connected interfaces meet the PELV requirements.

oConnect the connector to CN3 Encoder-1.

oVerify that the connector locks snap in properly.

Route the cables from the motor and the encoder to the device (starting from the motor). Due to the pre-assembled connectors, this direction is often faster and easier.
