4.3 Building of SIO communication network (SIO communication)
4.3.1 Wiring
(1) Basic
Item Contents
Number of connecting units 16 axes max. (Depends on the operation mode. Refer to “1.4 Features”)
Communication cable length Total cable length 100m or shorter
Communication cable Two-paired twisted pair shielded cable
Terminal resistor Recommended cable: Taiyo Electric Wire & Cable
CAUTION
1. Provide a communication path via a bus connection, and be sure to connect a terminal resistor at the
end. A terminal resistor is incorporated into the gateway unit side, therefore, it is unnecessary to connect
it.
2. The communication cable should be supplied by customer. If the recommended communication cable
is not used, use an electric wire size AWG22.
(2) Link connection for PCON-SE, ACON-SE
