摘要
Floor re-leveling apparatus including a microprocessor; cage position detectors produce outputs representative of the position of the cage in any one of three sections, a normal floor arrival section, one other section immediately above the normal floor arrival section, and one other section immediately below the normal floor arrival section. A speed reference signal having a preferred characteristic is generated and an actual cage speed signal is compared with the reference signal.
