Encoder Connection
This section describes the encoder signal (CN2) names, functions, and connection examples.
3.5.1 Encoder Signal (CN2) Names and Functions
The following table shows the names and functions of encoder signals (CN2).
∗ It is not necessary to connect these pins to the SERVOPACK.
3.5.2 Encoder Connection Examples
The following diagrams show connection examples of the encoder, the SERVOPACK, and the host controller.
(1) Using as an Incremental Encoder
∗ : represents shielded twisted-pair wires.
