4-2 Function Mode Analog Input (FV, FI) The Inverter has two types of analog input terminals. FV-FC terminal: 0 to 10 V (voltage input) FI-FC terminal: 4 to 20 mA (current input) Simultaneous inputs are not acceptable. Do not connect the signal lines for inputs FV and FI simultaneously. 4 Functions This function is enabled with the frequency reference set to the terminal block (A001 or A201 = 01). The settings are as follows. (VR: FREQ adjuster) If AT is not allocated to any of the multi-function input, this means the AT input = OFF in the above table. External Frequency (Voltage/Current) Adjustment External Analog Input (Frequency Reference) FV-FC terminal:
0 to 10 V (voltage input) FI-FC terminal: 4 to 20 mA (current input) Also set an output frequency for the FREQ adjuster on the Digital Operator. 4-10 Parameter No. Function name Data Default setting Unit A005 FV/FI selection 00: Switches between FV/FI via terminal AT 01: Operation via terminal AT is disabled 02: Switches between FV/FREQ adjuster via terminal AT 03: Switches between FI/FREQ adjuster via terminal AT 00 Related functions A011 to A016, A101 to A105, A151 to A155, C001 to C006 A005 set value 00 01 02 03 AT terminal input status OFF ON OFF ON OFF ON Analog input enabled FV-FC FI-FC FV-FI FV-FC VR FI-FC VR Parameter No.
