03-27
AFM2 Output Bias
Default: 0.00
Settings -100.00–100.00%
 Example 1, AFM2 0–10 V is set to the output frequency, the output equation is:
10 V × (output frequency / Pr.01-00) × Pr.03-24 + 10 V × Pr.03-27
 Example 2, AFM2 0–20 mA is set to the output frequency, the output equation is:
20 mA × (output frequency / Pr.01-00) × Pr.03-24 + 20 mA × Pr.03-27
 Example 3, AFM2 4–20 mA is set to the output frequency, the output equation is:
4 mA + 16 mA × (output frequency / Pr.01-00) × Pr.03-24 + 16 mA × Pr.03-27
 This parameter sets the corresponding voltage of the analog output 0.

03-28
AVI Terminal Input Selection
Default: 0
Settings 0: 0–10 V
1: 0–20 mA
2: 4–20 mA

03-29
ACI Terminal Input Selection
Default: 0
Settings 0: 4–20 mA
1: 0–10 V
2: 0–20 mA
 When you change the input mode, verify that the external terminal switch (SW3, SW4)
corresponds to the setting for Pr.03-28–Pr.03-29.
 When you change the setting, proportion to the corresponding AVI and ACI will change to default.
03-30
PLC Analog Output Terminal Status
Default: Read only
Settings Monitor the status of the PLC analog output terminals
 Pr.03-30 displays the external multi-function output terminal that used by PLC.
 For Example:
When Pr.03-30 displays 0002h (hex), it means that AFM2 is used by PLC.
