    2 Speed 1 Winding 3 Phase Motors

    On my motor I have L1=4 L2=5 L3=6 powered 1,2,3 open and the motor will hum and move a little bit before kicking out the overload on my VFD. When Powering L1=1 L2=2 L3=3 with 4,5,6 open it works fine.

    Thank you for the link, that may explain my problem. At a minimum It appears that I have 4,5,6 connected to the wrong phases.
