Issue:
Using a standard 0-10Vdc input on a bipolar input

Product Line:
ATV31, ATV312, ATV61, ATV71,

Environment:
All series

Cause:
At 5Vdc the drive ramps to full speed.

Resolution:
Must use a bipolar signal to get the proper scaling and reference.
Bipolar analog input 0 ± 10 V (max. safe voltage ± 30 V)
The + or - polarity of the voltage on AI2 affects the direction of the setpoint
and therefore the direction of operation.
