3.6 Encoder Connection
This section describes the encoder signal (CN2) names, functions, and connection examples.
3.6.1 Encoder Signal (CN2) Names and Functions
The following table shows the names and functions of encoder signals (CN2).
∗ These do not need to be connected for an incremental encoder.
3.6.2 Encoder Connection Examples
The following diagrams show connection examples of the encoder, the SERVOPACK, and the host controller.
(1) Incremental Encoder
∗1. The pin arrangement for wiring connectors varies in accordance with the servomotor that is used.
∗2. : represents shielded twisted-pair wires.
