Regarding VFD's A poly phase input unit may be used even if single phase is the only power avilable. The VFD must be sized a bit (1.5 -2 X) to accommodate the current through the DC rectifiers. The units I have (a Toshiba and two Siemens) all came by way of E-bay (New in box) and cost less than $50 each, 7.5 and 5 HP. List price would have been much greater.
Just a bit of information. Cal ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
