14.5.2 EzCOM Settings
• Set a station number for [CF-02] to each inverter of
the EzCOM network, avoiding overlapping a station
number. While doing so, make sure to assign a
station number 01. The inverter with the station
number 01 will be the "controlling inverter".
• Set the communication selection of controlling
inverter to EzCOM communication's "controlling
inverter" [CF-09]=02. Set the communication
selection of other
communication [CF-09]=01.

• Set the EzCOM communication start method
[CF-22] to the controlling inverter. If you selected
the input terminal start [CF-22]=00, assign 098
[485:EzCOM start] to any of input terminals 1 - 9, A
or B.
• To a master inverter, set the number of transmitting
data, the station
destination, register of transmission destination,
and register of transmission source that are
required for the master inverter to write the data
(see the following table).

*1) When you provide multiple master inverters, set
consecutive station numbers (01, 02, 03, ...) to
them. If the numbers are not consecutive, the
inverters cannot perform communication.
*2) Note that the relationship between the master
start/end station number settings must be
[CF-20] ≤ [CF-21].
