4.7 Absolute Encoders4-374 Operation4.7.1 Connecting the Absolute EncoderThe following diagram shows the connection between a servomotor with an absolute encoder, the SERVO-PACK, and the host controller.(1) Using an Encoder Cable with a Battery Case∗1. The absolute encoder pin numbers for the connector wiring depend on the servomotors.∗2. : represents shielded twisted-pair wires.∗3. If you use an absolute encoder, provide power by installing an encoder cable with a battery case (model: JUSP-BA01-E) or install a battery on the host controller./PCOENC34CN2171819202122CN1SG16PAO/PAOPBO/PBOPCOAbsolute encoder(Shell)Battery*3SERVOPACKPhase APhase BPhase CConnectorshellConnectorshell*2*2*10 VHost controller5612PG5VPG0VPS/PSBAT(+)BAT(-)Phase APhase BPhase CRRRApplicable line receiver:SN75ALS175 or MC3486 manufacturedby Texas Instruments or the equivalentTerminating resistance R: 220 to 470 ΩEncoder cablewith battery caseSN75ALS174 output linedriver manufactured byTexas Instruments or theequivalent+ -
