High-function General-purpose Inverter 3G3RX-V1 User’s Manual (I578-E1)
Set the following external analog input (frequency reference):
• FV-FC terminal: 0 to 10 V (Voltage input)
• FI-FC terminal: 4 to 20 mA (Current input)
• FE-FC terminal: –10 to 10 V (Voltage input)
And the output frequency for the volume adjuster on the Digital Operator.
By default, each analog input is set to reach the maximum frequency at 9.8 V or 19.8 mA.
