Chapter 12 Description of Parameter SettingsC2000-HS
 When the settings for Pr. 03-00–Pr. 03-02 are the same, the AVI input is selected first.
Analog Input Bias (AVI)

Settings
 Sets the corresponding AVI voltage for the external analog input 0.
Analog Input Bias (ACI)

Settings
 Sets the corresponding ACI voltage for the external analog input 0.
Analog Voltage Input Bias (AUI)

Settings
 Sets the corresponding AUI voltage for the external analog input 0.
 The corresponding external input voltage / current signal and the set frequency is 0–10V
(4–20mA) corresponds to 0–maximum frequency (Pr.01-00).
 Positive / Negative Bias Mode (AVI)
 Positive / Negative Bias Mode (ACI)
Positive / Negative Bias Mode (AUI)

Settings
 In a noisy environment, use negative bias to provide a noise margin. Do NOT use less than 1V to
set the operation frequency.
