Analog I/O Settings

This section describes the analog I/O signal settings for this inverter.
7-3-1

Analog Input (FV, FI)

This inverter has two types of external analog input terminals.
Frequency reference (Analog voltage input) between terminals FV and SC
This terminal also treats input via the variable resistor (volume) as voltage input to the
inverter.
Frequency reference (Analog current input) between terminals FI and SC
For 0 to 20 mA, set A103 to 0%.
For analog input start/end settings, refer to 7-3-5 Analog Input Start/End Function Settings on page 7-25.
Note By default, each analog input signal is adjusted to reach the maximum frequency at 9.8 V or 19.8 mA.
The table below shows analog-input related functions. Set each function according to your application.
