As the principal of the VFD works, bascially from AC to DC, then DC to AC. 2 o0 @9 M) p3 P$ {0 |4 h
0 M6 W3 X9 b) b+ T6 R1 c4 gThe phase rotation of the output of the VFD connecting to the motor is based on the sequence "open" or "close" controlled by the inverter pre-set inside; any changes to the phase rotation of the feeder will not affect the DC rotation, as DC is NO phase at all.

The only thing you can change the rotation of the motor is the output side of the VFD, NOT the input of the VFD. |
