CHAPTER 12: DESCRIPTION OF PARAMETER SETTINGS
03 - 04 Analog Input Bias 1 (ACI)
Settings
• It is used to set the corresponding ACI voltage of the external analog input 0.
03 - 05 AVI2 Analog Positive Input Bias
Settings
• It is used to set the corresponding AVI2 voltage of the external analog input 0.
• The relation between external input voltage/current and setting frequency: 0~10V (4-20mA) corresponds to 0-60Hz.
03 - 06 Positive/negative Bias Mode (AVI1)
03 - 07 Positive/negative Bias Mode (ACI)
03 - 08 Positive/negative Bias Mode (AVI2)
Settings
• In a noisy environment, it is advantageous to use negative bias to provide a noise margin. It is recommended NOT to use less
than 1V to set the operation frequency.
