Contrôleur de mouvement intégré

  • La solution haute précision pour le positionnement et la synchronisation, avec une réduction des coûts et de la complexité de système

    Pour optimiser les performances de nombreuses applications dans tous les secteurs d'industrie, un positionnement et une synchronisation précis sont nécessaires. Ces applications incluent notamment :

    • les tables rotatives 
    • les emballeuses
    • les étiqueteuses 
    • les convoyeurs 
    • les extrudeuses
    • les palettiseurs

    Jusqu'ici, les opérations de positionnement et de synchronisation étaient assurées par des systèmes servo. Toutefois, ces équipements servo sont onéreux. Leur mise en service est complexe et ils nécessitent des câblages supplémentaires. De plus, comme les servovariateurs ne fonctionnent pas avec des systèmes de contrôle en boucle ouverte, on observe un taux d'échec élevé. De nombreuses applications n'exigent pas les performances de dynamique élevée offertes par un servovariateur. Une solution alternative était alors d'utiliser un variateur. Toutefois, il fallait jusqu'à présent recourir à un module interne ou externe supplémentaire, ou à un codeur sur le moteur.

    Danfoss Drives a développé une solution innovante pour remplacer les servocommandes. Le contrôleur de mouvement intégré (IMC) est une fonctionnalité qui permet à un variateur d'atteindre une précision élevée dans les opérations de positionnement et de synchronisation sans qu'il faille de modules ou de matériel supplémentaires. L'IMC est maintenant configurable dans le logiciel du VLT® AutomationDrive FC 302.

    L'IMC présente de nombreux avantages. Il est compatible avec toutes les technologies de moteur conventionnelles, avec contrôle en boucle fermée ou en boucle ouverte, et offre un retour au point d'origine sans capteur avec détection de couple. Les variateurs sont adaptés aux applications par le biais d'un paramétrage simple. Cela signifie qu'il n'est pas nécessaire de connaître la technologie de servocommandes ni les langages de programmation. Ni codeur ni câble supplémentaire ne sont requis, ce qui réduit l'ingénierie, le temps et les coûts d'installation ainsi que la mise en service.
