Needs to wire in a 0-10vdc signal for speed control.
On the ATV32, ATV61 and ATV71 drives, you can wire the 0 to 10vdc signal to AI1+ to com as reference speed 1, and you can program AI2 in menu the IO menu to set up AI2 as a 0 to 10vdc speed reference 2.
Please note that there is a factory installed jumper between AI- and com that allows this input to work with a 0 to10vdc input. If you remove the jumper, then it becomes an -10vdc to +10vdc input.
On the ATV312, the 0-10vdc signal is landed on AI1 only.
