| (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. |
