• On each inverter, set the station number in the Communication Station No. Selection (C072)
so that they do not overlap among the inverters. Do not forget to set the station No. 1, which
serves as the management inverter.
• On the management inverter, set the Communication Selection (C096) to 02 (Co-inverter
communication (management inverter)). For other inverters, set the Communication Selec-
tion (C096) to 01 (Co-inverter communication).
• Set a station number 1 to 8 on inverters that serve as the master inverter. To switch the mas-
ter inverter among more than one inverter, the station numbering must be sequential. On the
management inverter, set the smallest master station number in the Co-inverter Communica-
tion Starting Station Number (C098) and the largest master station number in the Co-inverter
Communication Ending Station Number (C099).
• In the Co-inverter Communication Start Selection (C100), set how to start inverter communi-
cations. When C100 is set to 00 (Start via 485 terminal), set one of the Multi-function Input S1
to S7 Selection (C001 to C007) to 81 (Start co-inverter communication).
• In P140 to 155, set the following parameters, which are required when the master inverter
writes data: the number of sent data, recipient station number, recipient register address, and
sender register address.
(1) The master inverter sends data to one or more slave inverters according to the set-
tings for that master inverter.
(This data is also sent to the management inverter that does not serve as the master
inverter.)
(2) The management inverter sends the master switching command and the master
inverter is switched accordingly.
(3) The next master inverter sends data to one or more slave inverters in the same man-
ner as explained in step (1).
(This data is also sent to the management inverter that does not serve as the master
inverter.)
(4) Steps (2) and (3) are followed repeatedly.
Note
Because this inverter is designed to establish co-inverter communication as broadcast communications
(Station No. 00), communications data is sent to all stations. Therefore, slaves that are not specified as the
recipient on the master side receive the data once, but discard internally the data not addressed to them.
