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
