7-1-3 Frequency Reference Input Selection (n004)

• Select the method to input the frequency reference into the Inverter in remote mode.
• Ten methods can be used to input the frequency reference in remote mode. Select the ideal method
according to the application.

1 Frequency reference 1 (024) is enabled.
2 Frequency reference control terminal for 0- to 10-V voltage input is enabled.
3 Frequency reference control terminal for 4- to 20-mA current input is enabled.
4 Frequency reference control terminal for 0- to 20-mA current input is enabled.
5 Pulse train reference control terminal is enabled.
6 Frequency reference through communications is enabled.
7 Multi-function analog voltage for 0- to 10-V input is enabled.
Used only if two analog inputs are required in PID control.
8 Multi-function analog current for 4- to 20-mA) input is enabled.
Used only if two analog inputs are required in PID control.
9 Frequency reference through option (DeviceNet communications) is enabled.
Note 1. To input the frequency reference through RS-422/485 communications, set this parameter to
6. Then the frequency reference only through RS-422/485 communications will be enabled.
Note 2. The frequency reference can be input through RS-422/485 with multi-function input settings
as well. For details, refer to 7-1-4 Setting the Multi-function Inputs.

7-1-4 Setting the Multi-function Inputs (n050 to n056)

• In addition to the methods described above, the RUN command and frequency reference can be input
through RS-422/485 communications by setting the value 18 in any one of the parameters from n050
to n056 (multi-function input).
• Subsequently, the following operations are selectable in remote mode. None of these parameters,
however, can be changed while the operation command is being input.
When the function-set input terminal is OFF, the RUN command will be executed according to the
setting in n003 (RUN command selection) and the frequency reference will be executed according
to the setting in n004 (frequency reference selection).
When the function-set input terminal is ON, the Inverter will operate according to the RUN command
and frequency reference through RS-422/485 communications.
