As the principal of the VFD works, bascially from AC to DC, then DC to AC.

% \. R; E9 b, t1 \& s2 rThe 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.# b" ^: ^' E" j; E& h0 s7 V4 r

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