Anyone know a good place to purchase a high frequency VFD? We had the drive in one of our CNCs die. The old drive was a HSD DS15000. The spindle is an 18kw 24000rpm 4pole HSD router motor. The old drive is rated for 1-1000hz and that seems to be the problem, all of the off the shelf drives I can find are limited to output frequencies less than 500hz which would limit our spindles top speed to only 15000rmp. Our machine builder quoted us for a Yaskawa V1000 drive with 1000hz firmware (model# VU4A0038FAA-134) that they do have in stock but they are marking up their price to more than double the normal list price for that drive. Every other place I've checked with so far are quoting us months long lead times for that drive.
I don't have to have a Yaskawa drive, I think I'd be ok with any drive capable of 15kw and at least 800hz output. (Oh, it would be nice if it would fit in the cabinet where the old one did, have about 9inches x 15inches of space there.) Anyone have any suggestions for a good source for "obtainable" drive that would fit the bill? For example we have a machine with a Fuji Frenic drive with 0-1000hz, but I can't find any info on buying a new equivalent, all the new Frenic drives I can find have max frequencies under 500hz. I'm guessing it is similar to Yaskawa for most other manufacturers where you have to live in the right part of the world, ask nicely and then maybe they might sell you a drive with the "special" HF firmware.
