be connected
16 axes max. (depending on the operation mode)
Communication cable length Total cable length: 100 m or less
SIO communication main line Twisted-pair shielded cable (AWG22)
Recommended brand: Taiyo Electric Wire & Cable HK-SB/20276 x L, 2P x
AWG22
Terminal resistor
220 Ω, 1/4 W
Teaching pendant PC, PLC
* The SIO communication main line must be prepared by the customer.
Each one unit of the junction, E-Con connector and terminal resistor are supplied with the controller link
cable.
Caution: [Note 1] If normal communication cannot be performed with a communication error occurring when
the total communication cable length is 10 m or more, connect the terminal resistor to the
last axis.
[Note 2] For the power supplies of the SIO converter and all controllers, make 0V in common.
When using the +24 V pin as the grounding point (+ common), confirm that the GND pin is
not connected to ground.
Exercise caution particularly when connecting a PC. If the RS232C communication cable
is connected directly, the +24-V power supply may be shorted because the GND and FG
pins are connected inside the PC.
[Note 3] Connect a shielded cable to FG on an axis basis.
[Note 4] If the total link cable length is more than 30 m, use the wire size of 22AWG or larger.
