Lorsqu'une instruction de fonctionnement du corps d'ouverture et de fermeture est créée dans un état dans lequel une fonction de prévention de capture n'est pas actionnée, l'unité de commande MLI du circuit de commande fait vibrer le corps principal de moteur dans une plage audible, de sorte que le corps principal de moteur exécute une opération d'émission de son, en incluant la fréquence de la plage audible dans la fréquence de commande pour la commande MLI avant ou pendant un fonctionnement du corps d'ouverture et de fermeture, le fonctionnement se faisant en fonction de l'instruction de fonctionnement.
