∗1. The pin arrangement for wiring connectors varies in accordance with the servomotor that is used.
∗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.
• When Installing a Battery on the Encoder Cable
Use the encoder cable with a battery case that is specified by Yaskawa.
Refer to the multi-winding drive system catalog for details.
• When Installing a Battery on the Host Controller
Insert a diode near the battery to prevent reverse current flow.
