a. Detail connection diagram
Details of SIO link connection are illustrated below. Controller link cables are available as options, but
the customer must provide the communication trunk.
b. Producing a communication trunk
[1] Strip the sheath of a double shielded twisted-pair cable by
approx. 15 to 20 mm.
[2] Twist the shield wires and solder them onto the vinyl
wires of AWG22 or equivalent.
[3] Place a cable protection tube over the cable.
[4] Insert the core wires, without stripping them, into the
cable insertion holes in the connector (SDA, SDB,
GND, FG).
[5] With the cable inserted in the press-fit cable housing, apply
pressure from above to pressure-weld the core wires.
[6] Heat-treat the cable protection tube.
e-CON connector pin numbers
Always insert a terminal resistor (220
Ω, 1/4 W) at the end of the communication trunk
(between pins 1 and 2 of the e-CON connector).
