Operation
4.5.1 Connecting the Absolute Encoder
The following diagram shows the connection between a servomotor with an absolute encoder, the SERVO-
PACK, and the host controller.
(1) Using an Encoder Cable with a Battery Case
∗1. The absolute encoder pin numbers for the connector wiring depend on the servomotors.
∗2. : represents shielded twisted-pair wires.
∗3. When using an absolute encoder, provide power by installing an encoder cable with a JUSP-BA01-E Battery Case or
install a battery on the host controller.
