You can use six analog input functions in total with the functions for A1 to A3 on the drive
when you connect an AI-A3 option card.
Set F2-01 = 2 to enable F2-04 (Terminal V1 Signal Level Select) to F2-15 (Terminal V3
Bias Setting). You can use these parameters to select an analog input function, and set the
gain and bias for terminals V1, V2, and V3 for AI-A3 individually.
When you select the signal level, set the DIP switch S1 to S3 on the AI-A3 option card to
align with the input source and set these parameters:
• F2-04 (Terminal V1 Signal Level Select)
• F2-08 (Terminal V2 Signal Level Select)
• F2-12 (Terminal V3 Signal Level Select)
Figure 32 shows the analog input for terminal A1, and Figure 33 shows the additional input
for AI-A3 terminal V1.
