So I converted a 2 HP, 3 phase 220 hydraulic pump to single phase 220 with a VFD as in pic rel. It runs a few minutes and the trip on the start coil pack pops. Draws steady 1800W or so. Jumping over start coils causes error on VFD and no start. Can I move the VFD between the contactor and the start coils so they're between the VFD and the motor? Or did I do something else wrong anyone can spot? Is there too much current now that 2 legs of 120 are passing through the start coils instead of 3 legs of 220? Do they need upgraded? Why does the VFD seem to need them in the first place? Ideas?
