The invention relates to an elevator safety system (200) for an elevator system (1000) comprising an elevator drive system (160) comprising: an elevator hoisting machine (165), an elevator brake composition (180); a brake controller (185), a motor drive (175), and a safety function (177), the elevator safety system (200) comprising: at least one sensor (195) and a safety controller (210) configured to: obtain (410) data on a control state of the elevator brake composition (180), obtain (420) sensor data, and generate (440) a safety signal to supply VVVF voltage signal in response to: a detection (430) that the control state corresponds to the braking state, and a detection (430) that the operation of the elevator brake composition(s) (180) does not correspond to a braking operation. The invention also relates to a method, an elevator system (1000), and a computer program.
