Title
(EN) SYSTEM AND METHOD FOR ELECTRIC MOTOR CONTROL IN A MANUFACTURING ENVIRONMENT
(FR) SYSTÈME ET PROCÉDÉ DE COMMANDE DE MOTEUR ÉLECTRIQUE DANS UN ENVIRONNEMENT DE FABRICATION
Abstract
(EN)
A control system for an electric motor in a manufacturing environment, the control system including: a safety relay; and a power reduction circuit, wherein, when the safety relay is triggered, the power reduction circuit automatically limits the power supplied to the electric motor from a main power source such that the electric motor operates in a predetermined safe mode. A method for controlling an electric motor in a manufacturing system, the electric motor having a main power supply, the method including: monitoring the manufacturing system associated with the electric motor for a change in condition; on detecting a change in condition: limiting a power supplied to the electric motor, via a power reduction circuit, such that the electric motor operates in a predetermined safe mode. The power reduction circuit includes a reduced power supply and a means of dropping the power supplied to the electric motor quickly.

La présente invention porte sur un système de commande d'un moteur électrique dans un environnement de fabrication, le système de commande comprenant : un relais de sécurité ; et un circuit de réduction de puissance, le circuit de réduction de puissance limitant automatiquement, lorsque le relais de sécurité est déclenché, la puissance fournie au moteur électrique provenant d'une source d'alimentation principale de sorte que le moteur électrique fonctionne dans un mode sécurisé prédéfini. L'invention concerne également un procédé de commande d'un moteur électrique dans un système de fabrication, le moteur électrique comprenant une alimentation électrique principale, et le procédé consistant : à surveiller un changement d'état du système de fabrication associé au moteur électrique ; et lors de la détection d'un changement d'état, à limiter une puissance fournie au moteur électrique, par l'intermédiaire d'un circuit de réduction de puissance, de sorte que le moteur électrique fonctionne dans un mode sécurisé prédéfini. Le circuit de réduction de puissance comprend une alimentation électrique réduite et un moyen permettant de faire chuter la puissance fournie au moteur électrique plus rapidement.
