10 August 2022

Issue:
Analog Input designed for a bipolar -10v to +10v input on the ATV32 drives

Product Line:
Altivar ATV32

Environment:
All

Cause:
AI2 is default for -10v to +10v input.

Resolution:
Analog input AI2 is capable of the bipolar input and is factory set as such.  Check it by navigated through menus:
ConF - FULL - IO - AI2 - 
Parameter AI2t = n10U

 Bipolar analog input 0 ± 10 V (maximum voltage ± 30 V)

The + or - polarity of the voltage on AI2 affects the direction of the set point and therefore the direction of operation.
