Not that I can see. It flashes from Base Block to the running screen but it only tries for maybe 1 second. No, not a specific drive fault. It all started with an 83 & 109, position loss. once the car got to the top floor on 77 then the position loss went away. Can't run it to the bottom to perform shaft setup. Drive model is CIMR-LK4A0075AAA, at least that's the number on the front of the drive. The alarm light does come on the drive but all 3 cars in the group do so not sure that is any real indicator.
