  • Controlling a drive motor of an elevator installation
    Patent number: 8863908
    Abstract: A movement of an elevator cage is detected by an elevator control on the basis of signals of a rotary encoder, coupled with a rotational movement of the drive motor or the drive pulley. Before movement of the cage begins, a movement plot in the form of a trip/speed profile is calculated for travel of the elevator cage from an instantaneous elevator cage position to a destination stopping point position. An anticipated slip between the drive pulley and a support means is included in the calculation of the trip/speed profile, and during the travel of the elevator cage a rotational movement of the drive motor and thus of the drive pulley is controlled by the elevator control in dependence on the calculated trip/speed profile and on signals of the rotary encoder.
