Detailed Descriptions of P4.24 AI V/Hz Calculated Selection Settings
Setting: Function Function Description
0: All Inputs Use
Bias and Gain
All analog input signals are calculated by using bias and gain (P4�10~P4�23)�
1: AI1 Custom V/Hz
AI1 is calculated by using frequency and voltage/current in Low/Mid/
High-Point format (P4�25~P4�48)� Other analog input signals are calculated by
using bias and gain�
2: AI2 Custom V/Hz
AI2 is calculated by using frequency and voltage/current in Low/Mid/
High-Point format (P4�31~P4�36)� Other analog input signals are calculated by
using bias and gain�
3: AI1 & AI2
Custom V/Hz
AI1 & AI2 are calculated by using frequency and voltage/current in Low/Mid/
High-Point format (P4�25~P4�36)� Other analog input signals are calculated by
using bias and gain�
4: AI3 Custom V/Hz
AI3 is calculated by using frequency and voltage in Low/Mid/High-Point
format (P4�37~P4�48)� Other analog input signals are calculated by using bias
and gain�
5: AI1 & AI3
Custom V/Hz
AI1 & AI3 are calculated by using frequency and voltage/current in Low/Mid/
High-Point format (P4�25~P4�30, P4�37~P4�48)� Other analog input signals are
calculated by using bias and gain�
6: AI2 & AI3
Custom V/Hz
AI2 & AI3 are calculated by using frequency and voltage/current in Low/Mid/
High-Point format (P4�31~P4�48)� Other analog input signals are calculated by
using bias and gain�
7: All Custom V/Hz
All analog input signals are calculated by using frequency and voltage/current
in Low/Mid/High-Point format (P4�25~P4�48)�
