I have a KCM831 with V3F25 drive that will not run at all. Throwing two faults: 26-drive not ok and 83-position lost. Showing position 0 and I have a speed > 0.1 m/s light on the CPU board that stays on. Drive gone? Any help would be appreciated.
I've had that as well , maybe I got lucky but I kept powering down until the parameters came back. Took about 10 power cycles tho. Worth a shot if you haven't done so already.
