Abstract
L'invention concerne un procédé de commande d'un actionneur de levage (514) de bras et d'un actionneur d'inclinaison (524) pour commander le positionnement d'un support d'instrument (530) couplé à un bras de levage (520) d'une machine électrique. Un signal d'activation est reçu d'un dispositif d'entrée de validation (570). Un signal de commande de bras de levage est reçu d'une entrée de commande (562) de bras de levage commandant un déplacement du bras de levage. L'actionneur de levage de bras est commandé en réponse à la réception à la fois du signal d'activation et du signal de commande de levage de bras pour déplacer le bras de levage vers une position de levage cible de bras, et pour déplacer le support d'instrument ou le maintenir selon une orientation de support d'instrument cible par rapport à une direction gravitationnelle.
