How many amps do you have for your input supply,you would need up to 25 amp supply to run this VFD/spindle on single phase, this may be where the problem is, one thing you can try is to take the VFD control module off the VFD and then replace it, this may reset this drive fault, worth a try, just make sure you have enough supply for the drive/spindle
With the Oco fault this also shows a component has failed I did not pick up on this before, no matter what you do this in going to keep showing up something in the drive has failed most likely the IGBT has failed, these can fail from parameters set wrong, cutting the power while the spindle is at high speed, shorting out the IGBT which happens a lot
