I operate a CNC router table with a high speed spindle. I'm looking to upgrade to a new spindle but need to know if the variable frequency drive I currently have will work with this new spindle. The new spindle has the following stats: 300Hz, 1kw, 18000RPM. The frequency drive is made by LS Industrial Systems - Starvert SV008IC5-1F The info on their website suggests that this particular drive can reach 400HZ, but I’m not sure about the other details, especially whether or not 1kw is too high. More info is available using this link: http://eng.lsis.biz/product/product/introduce/ecatalog_viewStream.asp?catalog_id=288&fileNum=1 Any advice would be welcome.
