Hi Guys
Finally got around to setting up the Spindle control with UCCNC - AXBB-E and my HY VFD.
Everything is working great apart from the RPM is not accurate.
When Sset calls for 12000 RPM the VFD is correct and shows 12000 RPM
When Sset calls for 16000 RPM the VFD only reach's about 14800 RPM just about 10% difference
When Sset calls for 1800 rpm the VFD only reads 16500 RPM
When Sset calls for 24000 RPM VFD only shows 20000 RPM

The error gets bigger the higher the RPM
What settings do I need to adjust to get the VFD to reach the correct RPM?



Cheers
