Function

:Selection of monitor display selection

This parameter is used to change the item displayed when the power is turned on.

When the power is turned on, the operation frequency is displayed by default like this: “” or “QHH”. You can change this default monitoring item, using H. In that case, however, no prefixes (such as V and E) will be displayed.

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.Monitoring the inverter’s operation status (such as output frequency, current and voltage) Commands to the inverter (such as RUN and STOP commands)Reading, 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)

The following unit and cables are optionally available for common serial communications.

RS232C conversion unit (Model: RS2001Z)

Communications cable (Model: CAB0011 (1m), CAB0013 (3m), CAB0015 (5m))

Cable with a built-in RS232C conversion unit (Model: 20035)

RS485C conversion unit with a terminal board (Model: RS4001Z, RS4002Z)

Communications cable (Model: CAB0011 (1m), CAB0013 (3m), CAB0015 (5m))

Note: Use a cable 5 m or less in length to connect an inverter and an optional common serial unit.
