 : 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.
