I found both the spindle and this VFD acceptable and good value. Both connect to my KRMx02 CNC effortlessly and in full control. However, the spindle runout is not less than 0.005mm. This is closer to 0.00635mm (0.00025 inch) but is acceptable. I also have a water-cooled spindle with almost the same runout. I would and will recommend this combo to my KRMx02 readers.
