(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.)
