I have a Huanyang 2.2 kW water-cooled spindle and I'm controlling it with Mach 4. The spindle will only go up to 12000 RPMs instead of the 24000 RPMs that it is supposed to be running at. I have tried a total factory reset of the VFD but it still does not work. The spindle runs fine and at the correct speed anywhere from 7200 RPMs to 12000 RPMs. The rpm of the spindle is checked with a laser tachometer. Any ideas? Here are my settings:
