I bought my 2.2kw spindle & VFD in March from wholesalermultifunction (UK), installed and test it only with no load. Yesterday I started my first project and after some simple tests in acrylic with a 4mm 2-flute end-mill some sparks and smoke escaped from the VFD and both 16A fuses tripped. After that it started normally but only until I pressed the spindle run button. Another round of sparks and smoke with no fuses tripped and this time it was dead.
I followed the VFD setup parameters from the forum and checked them twice. The only difference is that I connected the mains to S and T instead of R and T but the manual says that I can connect to any of the three.
Any thoughts? Do I have any chance to have it replaced? Could have been my fault somehow?
Paul.
