★ : Split the cable among terminal blocks.
(1) Send data from the host computer.
(2) The inverters receive data from the host computer and the inverter number is checked.
(3) When * is next to the position of an inverter number, it is judged a broadcast. The command is
decoded and processed.
(4) To prevent data conflicts, only inverters where * is overwritten to 0 can reply with data to the host
computer.
(5) As a result, all inverters are operating with the broadcast operation frequency command.
Note: Specify inverter numbers by group for group broadcasts.
(Function only for ASCII mode. For parity mode, see the Communications Function Instruction Manual.)
(Ex) When *1 is set, inverters 01, 11, 21, 31 to 91 can be broadcast to.
In this case, the inverter specified in 01 can reply.
To enable easier management and maintenance of the inverter, it is possible to enter the identification
number.
