protocol
• Function
Function The VF-FS1 Series allows a data communication network to be constructed for exchanging
data between a host computer or controller (referred to collectively as the computer) and the inverter by
connecting an internal RS485 communication function or optional USB communication conversion unit.
<Computer-linking functions>
The following functions are enabled by data communication between the computer and inverter
(1) Monitoring inverter status (such as the output frequency, current, and voltage)
(2) Sending RUN, STOP and other control commands to the inverter
(3) Reading, editing and writing inverter parameter settings
<USB communication>
Data can be exchanged between one computer and one inverter.
<RS485 communication>
Data can be exchanged between the computer and each of the inverters connected.
