Hi everyone I got big problems I have a 6ra24 Drive and it faults when attempting to run the second phase of Auto Tune (P51=26). Drive begins to ramp up and in a few seconds shuts down with error code F042 Tachometer Fault.

Needs some troubleshooting ideas, as far I know the tach is wired and okay the best we can tell. The only thing I can think of at this moment is the shield is not grounded at the drive unit yet. Just hit me as I am sending this out. Thanks Everyone!
