Abstract: Power distribution is managed between a regenerative drive (10) connected to an elevator hoist motor (12), and a primary power supply (20) and electrical energy storage (EES) system (36) connected to the regenerative drive. A state-of-charge (SOC) of the EES system and a primary current flow between the primary power supply and the regenerative drive are measured. A direction and magnitude of secondary current flow between the EES system and the regenerative drive is then controlled as a function of the primary current flow and the SOC of the EES system. SOC of the EES system is maintained in a limited range except as necessary to maintain primary current flow below a threshold current.

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.
