The EM730/EM730E series inverter supports the master-slave communication function.
That is, one inverter works as the host and others as slaves. The slaves work according to the
command sent by the host, so that these inverters can work synchronously.
The inverter used as the host is set as follows:
F10.05=1: enable the master-slave communication function;
F10.06=1 or 2: select the current inverter as the host (only one inverter can be set as
the host in a network);
F10.07: select the variable to be synchronized, such as the output current (set
F10.07=5).
The inverter is used as the slave is set as follows:
