It has a PTC built in for the temperature and that will be wired in to the VFD in due course.

Looks like i have exactly 10:1 speed ratio from 10 to 100Hz which figures, works out nicely at 300 to 3000rpm.

Stopping in 1s is pretty impressive :)

Now to configure it for cnc control...
Will the momentum of the spindle and cutting tool not damage the belt if you continually stop quickly?
