Hi all,
looking for some help with a bridgeport cnc mill that has a mitsubishi vfd d700 inverter. the spindle slows and then stops when i start taking a cut with a 2" face mill .060" depth of cut. barely gets into the cut then stops. i tried changing some parameters in the vfd with no success. any help would be greatly appreciated!

Is this a new VFD install, or something that just started happening after running OK for some time?

I took a quick look at what I think is the manual for your VFD. It looks like you need, at a minimum, to set parameters 80, 82, 83, and 84 to the motor nameplate specs.
