Abstract

L'invention est relative à un convertisseur phase-incrément Une sortie d'un compteur de poursuite 38 comptant continuellement, est connectée à un registre d'erreur de phase 40 échantillonné par un dispositif de résolution 22 produisant un signal d'erreur de réaction de phase en fonction du déplacement angulaire d'un arbre rotatif. Le contenu binaire du registre à ce moment est appliqué à un convertisseur binaire/impulsions 42 fournissant des impulsions de sortie fonction du contenu du registre et appliquées au compteur de poursuite pour le faire avancer ou retarder de manière à rétablir la coïncidence avec le flanc avant du signal d'erreur de réaction de phase. Utilisation dans le domaine de la commande numérique.
