Issue:
Wiring 0-10V DC Signal in the ATV32, ATV312, ATV61 and ATV71 drives?

Product Line:
ATV61,  ATV71,  ATV31,  ATV312,  ATV32

Environment:
All serial numbers Open style VFDs

Cause:
Needs to wire in a  0-10vdc signal for speed control.

Resolution:
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.
