 Analog input bias/gain calibration (C12 (Pr.917) to C15 (Pr.918))
• The "bias"/"gain" function can adjust the relation between the output frequency and the setting input signal. Examples of
setting input signals are 0 to 5 VDC or 0 to 10 VDC, and they are externally input.
• Set the bias frequency of the terminal 1 input using C12 (Pr.917). (The initial value is the frequency at 0 V.)
• Set the gain frequency of the terminal 1 input using C14 (Pr.918). (The initial value is the frequency at 10 V.)

• There are three methods to adjust the bias/gain frequency setting voltage.
Adjustment by applying voltage between terminals 1 and 5 to set the voltage at the bias/gain frequency.

Adjustment by selecting the voltage at the bias/gain frequency without applying voltage between terminals 1 and 5.

Adjustment by only changing the frequency without adjusting the voltage.
