Communication function (common serial)

For details, refer to the Communications Equipment User's Manual.
• Function
The VF-nC1 series of inverters can be connected to a host computer, controller, and so on
(referred to as the computer) via RS232C or RS485 conversion units, so that they can be
operated on a network.
<Computer linking function>
Data is exchanged between an inverter and a computer.
①Monitoring the inverter's operation status (such as output frequency, current and voltage)
②Commands to the inverter (such as RUN and STOP commands)
③Reading, changing and writing inverter parameter settings
<RS232C communications>
Data is exchanged between one inverter and one computer.
<RS485C communications>
Data is exchanged between one computer and multiple inverters (a maximum of 64, or 63 for
binary codes)
