An elevator system includes an elevator car supported by an elevator rope wrapped around a sheave, such that a rotation of the sheave changes a length of the elevator rope between the sheave and the elevator car thereby controlling a movement of the elevator car within an elevator shaft of the elevator system. An elevator cable is connected to the elevator car and the elevator shaft to carry electrical signals to the elevator car. The operation of the elevator system is controlled in response to receiving a call for a movement of the elevator car requesting a change of the length of the elevator rope. A motion profile of the elevator car causing the requested change of the length of the elevator rope that minimizes the sway of the cable is determined according to a model of a cable relating a sway of the cable to a motion profile. Next, the motion of the elevator car is controlled according to the determined motion profile.
