Abstract (en)
[origin: EP0773180A1] The method derives a desired motion characteristic in a controller and passing it with motion parameters to a drive controller. If a safety limit is exceeded, the lift cabin is stopped. The same motion parameters are passed to a second controller for a reference drive so that a triggering part moved by the reference drive has the same motion characteristic. The triggering part is movably connected to the lift cabin so that a switch for stopping the cabin is triggered by the triggering part if the deviation of the lift cabin from the motion characteristic is greater than the safety limit.
