Why does an ATV312 operate the motor in reverse when a run forward command is given?

Issue:
Why did my ATV312 run the motor in reverse when a run forward command is given?

Product Line:
ATV312

Environment:
All models

Cause:
Motor runs backwards

Resolution:
Verify the run forward command:
In two- wire control, LI1 is run forward. 
In three- wire control, LI2 is run forward.
Monitor the logic inputs in Menu SUP > LIA- > LIS. 
If using local or remote keypad command, consider the setting for CtL > rot, Rotating direction and action of the FWD/REV button.

If the correct run command is confirmed, then reverse the phasing to the motor by swapping two of the motor leads at the output of the drive, Terminals U/T1-V/T2-W/T3.
