Are you check the wiring between the CNC and the spindle drive???
What trade and model is your CNC??? in CNC's Fanuc you have parameters where you put the maximum RPM's for the spindle maybe this parameter is bad...

I have some year ago this problem....
But for me was a only spindle parameter.
My machine have a mitsubishi spindle and sometime whit the electrical interruption or magnetic radiation, my spindle lost all data.
The tecnical eng. tell me a program to reput the data in the spindle and
in some second the machine go to run perfect.

If you have mitsubitshi spindle can be the same problem.
Cechk you spinlde drive. if you need i send my parameter (if the spindle is equal).

dear sir (echostar)
i have 2 of those machines a dm4400 and a dm4000, on one time the spindle would not turn because the brushes were gone and i mean really gone...so have a look at the brushes there is 4 of it on top of the motor...

second topo have a look at the spindle drive if there is voltage going to the motor if so check the wiring to the motor..

third topo look if there is an error light on top left of the spindle drive (ground fault) there is a fuse inside that could be blown up...it is a 10 amps...fuse..

i am now trying to upgrade one machine with a mach3 system complete with new drive so if anybody knows about doing it .....help me
