Applicable to Various System Configurations

■
Remote I/O communications and message communications are available as communications func-
tions. Normal control inputs are controlled by the remote I/O communications function. When neces-
sary, the message communications function is used to monitor each Inverter. It is possible to control
the selection of either the communications control input or local control input.
Note When connecting the DeviceNet Communications Unit/Card of the Inverter, use DCA1-5C10
Thin Cables and branch them from the T-branch Tap.
