Hallo everyone,
I have replaced my spindle to chinese spindle which has 24k rpm speed with shimpoenx E500 VFD. my problem is i only get 5000 max speed that written on UCCNC screen.
would anyone give me some advise.

VFD are generally not set up fully right out of the box.
You will likely need to change some perameters.
One to look for as an example is the setting for the max hz.
If you have a spindle that goes to 400hz and the vfd is only set to max 100hz. In this event I would expect to see a speed of no more 6krpm possible from spindle without a change.
There could be a couple or a few things that need changing

Read the manual.
