• Function
The VFS9 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
optional RS232C or RS485 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
<RS232C communication>
Data can be exchanged between one computer and one inverter.
<RS485 communication>
Data can be exchanged between the computer and a maximum of 64 inverters.
✩ The following are available as common serial optional units:
• RS232C communications conversion unit (Model: RS2001Z)
Communications cable (Model: CAB0011, 1m long; CAB0013, 3m long; or CAB0015, 5m long)
• RS485 communication conversion unit with terminal board (Model: RS4001Z)
Communication cable (Model: CAB0011, 1m long; CAB0013, 3m long; or CAB0015, 5m long)
Note 1.: Limit the distance between the common serial optional units and the inverter to 5m.
2.: Set Data transfer speed to 9600 bps or less if data exchange between the common serial optional units
and the inverter.
