Cause : Alt VelFdbk Loss comes when a feedback Loss has been detected for the source of P128 [Alt Vel Fdbk Sel]. The feedback loss could be due to a problem detected by the feedback option module selected by P128 [Alt Vel Fdbk Sel], or due to a loss in communication between the feedback option module and main control board.
