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