(2) Absolute Encoder
∗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
Σ
-V Series Product Catalog
(Catalog No.: KAEP S800000 42).
• When Installing a Battery on the Host Controller
Insert a diode near the battery to prevent reverse current flow.
