The AVI terminal default voltage mode is set to 0–10 V. To use the
current mode, the AVI must be switched to the current mode position
(0–20 mA / 4–20 mA), as the red frame below shows, and then set
Pr.03-28.
Voltage (AVI) mode
Impedance: 20 kΩ
Range: 0–10 V = 0–Max. Output Frequency (Pr.01-00)
Range switching according to Pr.03-00, Pr.03-28.
AVI resolution = 12 bits
Current (ACI) mode
Impedance: 250 Ω
Range: 0–20 mA / 4–20 mA = 0–Max. Output Frequency (Pr.01-00)
Range switching according to Pr.03-28.
ACI resolution = 12 bits
