○Wiring for communication cable
There are two methods of CompoBus/S slave connection, T branch type and Multi drop type. In T branch
type, the slave is connected to the branch cable from the main cable. In multi drop type, the slave is
directly connected to the main cable.
Note that it is not possible to separate the branch cable. Please use special branch crimped connector or
commercially available terminal blocks when separating the main cable to the branch cable.
When connecting communication cables to the SI unit, connect the BDH and BDL communication cables
to the BDH and BDL terminals. In addition, connect the communication power supply cables BS+ and BS-
to the BS+ and BS- terminals.
The communication lines of the special flat ribbon cable are decided as follows.
Note
If there is a noise generating source nearby, route the cable separately from the power cable or
high voltage cable to prevent noise and surge voltage from the unit.
Connect the cable correctly.
Wrong wiring may result in breakage of the SI unit and other devices.
