If your Beckman Coulter Optima ultracentrifuge flags d63, it's an indication that the drive thermostat mounted on the drive has overheated, causing an open circuit during a normal run, or it didn't cool down and deactivate after a 5-minute waiting period on power-up. In case of a power fail diagnostic during a normal run, the ultracentrifuge will shut down with brake.

In such an event, a Beckman-trained expert will check the drive, drive oil, drive fans, and the drive control system of the ultracentrifuge.
