5.9.1 Connecting the Absolute Encoder
The following diagram shows the connection between a servomotor with an absolute encoder, the multi-wind-
ing drive unit, 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. To prevent the influence of external noise, we recommend you connect a ferrite core on the motor end of the encoder
cable using two turns.
∗3. : represents shielded twisted-pair wires.
∗4. 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.
