Continuously getting over voltage faults on our 525 Drive when NOT running. I have increased the DC voltage parameter, installed reactor on line side then moved to load side. We do have surges in our line voltage, but have capacitor banks as well as the above mentioned devices installed. Have checked for any kind of correlation with other equipment, i.e. properly grounded, anything that could be causing a voltage surge or any kind of interference. Cant find anything other than our line fluctuation. Any suggestions as to what to do next?
