Title (EN) AUTOMATIC RESCUE OPERATION FOR A REGENERATIVE DRIVE SYSTEM
(FR) OPERATION DE SAUVETAGE AUTOMATIQUE POUR SYSTEME D'ENTRAINEMENT REGENERATEUR
Abstract: front page image
(EN)A system (10) continuously drives an elevator hoist motor (14) during normal and power failure operating conditions. A regenerative drive (30, 34, 36) delivers power to the hoist motor (14) from a main power supply (17) during the normal operating condition and from a backup power supply (24) during the power failure operating condition. A controller (12) operates the regenerative drive (30, 34, 36) to provide available power on the regenerative drive (30, 34, 36) to the backup power supply (24) during the normal operating condition.
(FR)L'invention concerne un système (10) entraînant de façon continue un moteur de dispositif de levage d'ascenseur (14) dans des conditions de fonctionnement normal et de panne de courant. Un circuit régénérateur (30, 34, 36) fournit une alimentation au moteur de dispositif de levage (14) à partir d'une alimentation principale (17) dans des conditions de fonctionnement normal et à partir d'une alimentation de secours (24) dans des conditions de panne de courant. Une unité de commande (12) actionne le circuit régénérateur (30, 34, 36) pour fournir la puissance disponible dudit circuit (30, 34, 36) à l'alimentation de secours (24) dans des conditions de fonctionnement normal.
