How do I configure my ATV312 drive for forward and reverse direction using +10/-10V speed reference?

Issue:
ATV312 configuration for forward and reverse using +10/-10V speed reference

Product Line:
Altivar 312 series drives.

Environment:
All models, All serial numbers.

Cause:
Customer needs to control the drive forward and reverse with a single run command and +10 to -10V input for speed/direction control.

Resolution:
AI2 input can be used for +10 to -10V input.   Configure parameter FR1 to AI2 under the CTL menu to have the drive look at AI2 as the primary speed reference.  Connect your +10/-10V speed reference between AI2 and COM on the drive.
