Wiring and Connection
(2) Absolute Encoders
∗1. The pin numbers for the connector wiring differ depending on the servomotors.
∗2. : represents twisted-pair wires.
∗3. When using an absolute encoder, install a battery in a battery case (JZSP-BA01)
of encoder cable, or install a battery on the host controller side to supply power.
∗4. Applicable line receiver: SN75ALS175 manufactured by Texas Instruments or MC3486, or the equivalent.
