Drive light flashing

We have an ultra centrifuge that has not had routine maintenance in several years. The instrument was functioning great until it was turned off and moved by some students. It does power on and pulls a vacuum as ot should. The centrofuge chamber will also hold a cold temperature. The rotor does spin freely on the spindle and the door seal is clean and has a thin film of vacuum grease on it. I do not think that the drive actually spins at all. I pulled some codes and they are below: 10,000 UAC No id rns 125 cnt 108 Hour 33 nin 0 dc 124 scp 124 ncp 124 uip I tried to purchase a service manual but they are not available any longer and Beckman is not super helpful.
