"Given away": Only the inverter with the selected inverter number conducts data processing. All other inverters, even if they have received the data, give it away and stand by to receive the next data.

*: Use the terminal board to branch the cable.

(1)

Data is sent from the host computer.

(2)

Data from the computer is received at each inverter and the inverter numbers are checked.

 

(3)

The command is decoded and processed only by the inverter with the selected inverter number.

 

(4)

The selected inverter responds by sending the processing results, together with its own inverter

 

 

number, to the host computer.

 

(5)

As a result, only the selected inverter starts operating in accordance with the operation frequency

 

 

command by communicating independently.

For details of the communication function, refer to the separate instruction manual, “VF-FS1 Serial

 

 

Communication Function”.

 

Note :

Limit the distance between the common serial optional units and the inverter to 5m.
