Les transducteurs spéciaux ke300a - 08 sont utilisés pour le stationnement instantané et le non - stationnement, la tension bus CC étant le principe central de commande, et l 'utilisation de ce algorithme de commande haute performance permet d' optimiser l 'efficacité de la tension bus CC.Après un traitement analytique intégré basé sur la mesure de la tension bus CC, l 'état de sortie de l' unité d 'entraînement est automatiquement ajusté, une relation raisonnable de distribution d' énergie de rétroaction de charge est établie et le Contrôleur d 'entraînement est maintenu entre 4 et 9 secondes sans coupure de courant.Lorsque l 'unité d' entraînement est complètement coupée et qu 'il n' y a pas d 'affichage, le réseau d' alimentation électrique peut être remis en marche automatiquement.Le conducteur ne signale pas de panne pendant toute la durée d 'une panne d' alimentation instantanée.
(1) DSP système de commande à grande vitesse
noyau de contrôle utilisant le processeur numérique à grande vitesse produit par Texas Instrumentation Corporation.Le système assure une haute vitesse et une haute stabilité.Il peut traiter complètement les opérations de commande les plus complexes.12 345 667 890 (2) La nouvelle technique de commande de vecteur sans PG, 1234 567 890, permet de commander un mouvement interrompu sans vecteur PG, avec un couple nominal pouvant atteindre 150% à 05hz; contribue à réduire la sensibilité aux paramètres du moteur et à améliorer l 'adaptabilité du site.Il peut également S' appliquer à la commande d 'enroulement, solution parfaite pour faire glisser plusieurs moteurs sur la même charge.
3) Caractéristiques des excavateurs
4) temps de réponse dynamique rapide sous contrôle vectoriel
PG inférieur à 20ms.
