Parameter Details1111.7 F: OptionsYASKAWA ELECTRIC SIEP C710617 01B YASKAWA AC Drive GA700 Technical Manual 719Note:When the AI-A3 card is not mounted in the drive, the functionality of analog input terminals A1 through A3 on the drive are enabledregardless of the setting of F2-01.0 : 3 channel individualTo increase the accuracy of A/D conversion while using the functions for terminals A1 through A3 on the drive asthey are, set F2-01 = 0. Multi-function analog signal can be input from terminals V1 through V3 for AI-A3. Thefunctions for terminals A1, A2, and A3 on the drive are redirected to terminals V1, V2, and V3 for AI-A3. Signalscan 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 inthe following figure are used to select the function to input the analog reference received from the AI-A3 card andto adjust the gain and bias of these signals.Figure 11.71 Analog Input Reference Individual Input Block Diagram1 : 3 channel additionTo 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 throughV3 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.Figure 11.72 Analog Input Reference Addition Input Block DiagramAdjust the Input State via F2-02 and F2-03The ratio (%) of the maximum output frequency output as the frequency reference when the bias set by F2-03 is0% 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 valueis 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.
