Inverter-to-inverter link function (FR-A800-E)
System configuration
The following shows the system configuration for using the inverter-to-inverter link function. The
master inverter can communicate with the slave inverters through one or two hubs (refer to the de-
scription of Pr. 1124 for the master/slave setting).
(Communication using the inverter-to-inverter function is not available for the inverters directly con-
nected to the router.)
