Abstract

An elevator system including an elevator shaft and at least one elevator cab which can move in the elevator shaft. The elevator system has a distributed control system having a first evaluation unit, respectively associated with the at least one elevator cab, and has at least one second evaluation unit, associated with the elevator shaft. A bus link connects the first evaluation unit and the at least one second evaluation unit to one another. The first evaluation unit has a set of limit curves containing limit curves for the actuation of a braking device and/or a safety gripping device that are calculated and scaled in line with a current operating state, the first evaluation unit being configured to trigger the safety gripping device or the braking device if one of the limit curves is exceeded. Defined ends of the limit curves limit a scope of movement for the at least one elevator cab.
