Issue:
Configuring the ATV320 drive for a bipolar +10/-10vdc speed control?

Product Line:
ATV32 and ATV320 Drives

Environment:
All

Cause:
Wants to set up the drive so 0 to 10vdc is FWD and 0 to - 10vdc is REV

Resolution:
AI2- [AI2 CONFIGURATION]
Programming

I/O menu
AI2 configuration

AI2t [AI2 Type] [Voltage +/-] (n10U)
Set this to (n10U) for Positive and negative voltage input.
[Voltage +/-] (n10U): Positive and negative voltage input +/- 10 V (the input is bidirectional)
UIL2 [AI2 min value] 0V
AI2 voltage scaling parameter of 0%.
UIH2 [AI2 max. value] V 10.0 V
AI2 voltage scaling parameter of 100%.

Note that the Min range is 0v and max is 10 vdc this will still allow for -10 to 10vdc  with 0-10v REV and 0 +10v FWD
