(2) Installing the Battery in the Host Controller
∗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.
• 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.
