Hi Brains trust.
trying to resolve an intermittent error with the FR-SE-2 spindle drive.
The drive is tripping out on over Voltage (Converter) somewhat randomly.
A week or so ago, I was in the middle of a cut and had the spindle drive trip on over voltage.
I checked the waveforms and found 1 Waveform missing so I have ordered replacement DK434 driver chips and installed it today.
Waveforms looks fine, including the response times etc.
I ran the usual warm up cycle and all went fine.
Then while running a very light cut (3000rpm - 12mm tool - 0.1mm/tooth feed - 1mm stepover/ 4mm DOC, it tripped out again on over voltage.
I reset it and reran the cut again (sped up through air cutting)and it tripped again.
I dropped the spindle speed to 2500 and feed down a bit also and it managed to complete the cycle ~ 25 mins.
Then while I was thinking about the next test to debug the problem (with the spindle stopped and in home position), the error occurred again with the spindle stationary.
I've had a look around and can't seem to find much on this.
Has anyone come across this error and resolved it or have any suggestions on where to look?
Cheers
Mick
