Verify the drive is receiving a forward run command:
In three- wire control, LI2 is run forward.
This can be done by monitor the logic inputs in Monitoring Menu non - I/O map - IOn - Logic Input State - LIS1 (in the ATV312 it is slightly different. SUP > LIA- > LIS).
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.
NOTE: the ATV312 when using the local keypad command has parameter to select which direction is authorized, or if both are. By default only Forward is enabled in this configuration.
