The AC drive supports a total of three AI terminals, among which AI1 and AI2 are provided
on the control board and AI3 is provided on the extension card.
Terminal Input Signal Characteristic
AI1-GND It receives the signal of 0–10 VDC.
AI2-GND
If J8 is shorted with the pin marked with "V", the AI receives the voltage signal of
0–10 VDC.
If J8 is shorted with the pin marked with "I", the AI receives the current signal of
0–20 mA.
AI3-GND It is provided on the extension card and receives the signal of -10 to10 VDC.
As external voltage/current signal, AI is used for inputting the frequency reference, torque
reference, voltage reference at V/F separation, and PID reference or feedback. The
corresponding relationship between the voltage/current and the actual reference or feedback
