Note:
When the AI-A3 card is not mounted in the drive, the functionality of analog input terminals A1 through A3 on the drive are enabled
regardless of the setting of F2-01.
0 : 3 channel individual
To increase the accuracy of A/D conversion while using the functions for terminals A1 through A3 on the drive as
they are, set F2-01 = 0. Multi-function analog signal can be input from terminals V1 through V3 for AI-A3. The
functions for terminals A1, A2, and A3 on the drive are redirected to terminals V1, V2, and V3 for AI-A3. Signals
can be set to have negative numbers using gain and bias adjustments when current is input.
Note:
• To set inputs individually, set b1-01 = 1 [Reference 1 Source = Analog Input].
• oPE05 [Run Cmd/Freq Ref Source Sel Err] is detected when F2-01 = 0 while b1-01 = 3 [Option PCB].
The following block diagram illustrates the individual input of analog inputs. H3-xx parameters as illustrated in
the following figure are used to select the function to input the analog reference received from the AI-A3 card and
to adjust the gain and bias of these signals.

1 : 3 channel addition
To set addition input, set b1-01 = 3 [Option PCB].
The frequency reference can be input directly. The resulting value of adding the input from terminals V1 through
V3 becomes the frequency reference.
To use the AI-A3 card as addition input, set F2-01 = 1.
The following block diagram illustrates addition input. Use F2-02 [Analog Input Option Card Gain] and F2-03
[Analog Input Option Card Bias] to adjust the analog reference gain and bias for addition input.

Adjust the Input State via F2-02 and F2-03
The ratio (%) of the maximum output frequency output as the frequency reference when the bias set by F2-03 is
0% is determined by the gain set by F2-02 and the addition input value.
Note:
A voltage input of 10 V or a current input of 20 mA is the 100% value for each channel.
The ratio (%) of the maximum output frequency output as the frequency reference when the addition input value
is 0% is determined by the bias set by F2-03.
Note:
A voltage input of 0 V or a current input of 4 mA is the 0% value for each channel.
