Method and system of controlling a counterweightless elevator system provided with an elevator car and a variable speed drive with an electric motor, wherein the elevator car load is weighed, and wherein the elevator system is controlled in order to reduce the physical/electrical dimensions of the system. The total mass of the elevator is defined by the equation Mtotal = Mcar (mass of the car) + A* Maxpayload, wherein Mcar is the mass of the car, A is a coefficient and Maxpayload is the maximal payload. If the payload supercedes A*Maxpayload the elevator is controlled so that the speed and/or acceleration of the motor is reduced, and/or the idle time of the elevator is increased. |
