Title (EN) SYSTEM AND METHOD FOR REDUCING SPEED OF AN ELEVATOR CAR
(FR) SYSTÈME ET PROCÉDÉ POUR RÉDUIRE LA VITESSE D'UNE CABINE D'ASCENSEUR
Abstract:
(EN) A system and method for controlling speed of an elevator car (4) in an elevator system (2) is disclosed. The elevator car (4) may have a speed governor (18) adapted to trip when an electrical tripping point of the speed governor (18) is reached. The elevator system (2) may also have a control system (28) for controlling operation of the elevator car (4), the control system (28) providing a speed reducing switch adapted to trip when a software tripping point of the speed reducing switch is reached, the software tripping point being reached before the electrical tripping point of the speed governor (18).
(FR) L'invention porte sur un système et sur un procédé pour commander la vitesse d'une cabine d'ascenseur (4) dans un système d'ascenseur (2). La cabine d'ascenseur (4) peut avoir un régulateur de vitesse (18) apte à se déclencher quand un point de déclenchement électrique du régulateur de vitesse (18) est atteint. Le système d'ascenseur (2) peut également avoir un système de commande (28) pour commander le fonctionnement de la cabine d'ascenseur (4), le système de commande (28) constituant un commutateur de réduction de vitesse apte à se déclencher quand un point de déclenchement logiciel du commutateur de réduction de vitesse est atteint, le point de déclenchement logiciel étant atteint avant le point de déclenchement électrique du régulateur de vitesse (18).
