4.3 Design of SIO Communication Network (SIO Communication)
4.3.1 Wiring
(1) Basics
Item Description
Number of connected units
16 axes max. (The specific number varies depending on the operation
mode. Refer to 1.4, “Features of Gateway Unit.”)
Communication cable length Total cable length: 100 m max.
Communication cable
Double shielded twisted-pair cable (AWG22)
Recommended cable: HK-SB/20276 X L 2P X AWG22
by Taiyo Electric Wire & Cable
Terminal resistor 220
Ω 1/4 W
Caution
1. Connect the communication path to a bus and always connect a terminal resistor at the end. A
terminal resistor is not needed on the Gateway Unit end, as the unit has a built-in terminal resistor.
2. The customer must provide the communication cable. If the recommended cable is not used, make
sure the size of the cable to be used is AWG22.
(2) Communication connection for PCON, ACON and SCON
*1 A terminal resistor (220
Ω, 1/4 W) is supplied with the controller link cable.
