3. Installation and Wiring
(2) Connecting the multiple axes
Item Description
Maximum number of units that can
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 :, 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: [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.
[2] For the power supplies of the SIO converter and all controllers, make 0V in common.
[3] Connect a shielded cable to FG on an axis basis.
[4] If the total link cable length is more than 30 m, use the wire size of 22AWG or larger.
[5] If the positive side of the 24-V power supply is grounded, do not connect the SIO converter
and the FG terminal of the PC to ground.
If the positive side of the 24-V power supply is grounded and no SIO converter is used, be
sure to use a SIO isolator (RCB-ISL-SIO). (Refer to the next page.)
