We've been having a bit of an intermittent error on one of our Puma 230MSB's. The alarm code is ALP-OU, which according to the book is an over voltage alarm, caused by too high of an input voltage, or regenerative resistor failure. The input legs to the servo drive measure 241-242V across each leg so the variance is minor. The high leg measures 208V to ground and is located on L1. The wiring is exactly the same, as are the measurements, to our other Puma 230MSB sitting right next to this one.
As I said, the problem is intermittent, some days it works fine, others it won't start at all. Of course this week we need it to run and it's fussing with us, so I'd like to get the problem addressed. The Servo drive itself says 200-230V rating (on both Puma's). Is it possible that the input voltage of 241V is enough in excess of the 230V drive rating that it's causing this intermittent issue?
