Note
● [1] CN3 and CN4 communication terminals can be used interchangeably. Their pin
assignments are exactly the same.
● CN3 and CN4 (communication terminals) are applicable to SV670C series products
for CANopen communication.
● CN6 (STO terminal) is only applicable to customized model ‑FS.
1.2 System Composition
● The servo drive is directly connected to an industrial power supply, with no
isolation such as a transformer. A fuse or circuit breaker therefore must be
connected to the input power supply to prevent electric shock in the servo system.
