Analog Input Adjustment

You can change the analog input gain. Use this function to fine-tune the analog input signal.
For how to set the scale conversion, for example, from 0-to-10 V to 0-to-5 V, refer to 7-3-5 Analog Input
Start/End Function Settings on page 7-25.
By default, each analog input signal is adjusted to reach the maximum frequency at 9.8 V or 19.8 mA.

Analog Input Start/End Function Settings

Use these functions to configure the relationship between the analog input signal (FV/FI) or the optional
Digital Operator's volume control (VR) signal and the frequency reference.
• In the FV/FI/VR Start Ratio (A013/A103/A163), set the minimum analog input value.
• In the FV/FI/VR Start Frequency (A011/A101/A161), set the output frequency for the analog input set
in the FV/FI/VR Start Ratio.
• In the FV/FI/VR End Ratio (A014/A104/A164), set the maximum analog input value.
• In the FV/FI/VR End Frequency (A012/A102/A162), set the output frequency for the analog input set
in the FV/FI/VR End Ratio.
• In the FV/FI/VR Start Selection (A015/A105/A165), set the output frequency from 0 V to the minimum
analog input value set in the FV/FI/VR Start Ratio.
• Setting the FV/FI/VR Start Frequency (A011/A101/A161) and the FV/FI/VR End Frequency
(A012/A102/A162) to 0.00 Hz disables the Start and End Frequency settings, which causes the ana-
log input function to work in the range of 0 Hz to the maximum frequency.
• With the default settings, this function works as follows.
Frequency reference (Analog voltage input)
between terminals FV and SC
Frequency reference (Analog current input)
between terminals FI and SC
VR (Volume control on optional Digital
Operator (Model: 3G3AX-OP01))
• By default, each analog input signal is adjusted to reach the maximum frequency at 9.8 V or 19.8 mA.
• To input a voltage of 0 to 5 V, set A014 to 50% and use the default settings for A011 to A104.
• To input a voltage of 0 to 20 mA, set A103 to 0% and use the default settings for A101/A102/A104.
