Issue:
Why does an ATV312 operate 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/V/W.
