The wrong VFD settings can cause an overheat due to overcurrent. Were you
running the spindle at lower RPMs? Router spindles generally don't like
running at speeds less than 6000rpm, especially if the VFD settings aren’t
right. The VFD needs to be set so that it reduces the voltage applied wi
Hi Todd, and thanks for the response!
Well the manufacturer only gave nominal and max speed for the spindle and a
couple of graphics to see the u.f. and p.f. curves to have some guidance.
I'm always using the spindle at 15000 rpm so I think that's ok. Also I've
been using it like this for more tha
By the way, the nominal frequency is 400 hz at 12000 rpm. Nominal voltage
is 380 volts but that varies of course when the VFD is working. Max
frequency is 800 hz at 24000 rpm but I never came close to that.
