Title (EN) CONTROL DEVICE, CONTROL METHOD, AND CONTROL PROGRAM
(FR) DISPOSITIF DE COMMANDE, PROCÉDÉ DE COMMANDE ET PROGRAMME DE COMMANDE
Abstract:
(EN) A control method according to an aspect of the invention includes a process for setting target fastening torque, a pulse interval of neighboring pulses, and an elevated value of torque per pulse, detecting last fastening torque at an Nth pulse (N is a natural number of 1 or more) after seating of a fastening member, setting pulse loading time at an N + 1th pulse and pulse strength at the N + 1th pulse based on the last fastening torque at the Nth pulse so that fastening torque at the N + 1th pulse coincides with a multiple of the elevated value, controlling a fastening tool based on the pulse interval, the pulse loading time, and the pulse strength so that last fastening torque at an N + Mth pulse (M is a natural number of 1 or more) reaches target fastening torque.
(FR) La présente invention, selon un aspect, concerne un procédé de commande comprenant un traitement consistant à définir un couple de fixation cible, un intervalle entre impulsions d'impulsions voisines et une valeur élevée de couple par impulsion, à détecter le dernier couple de fixation au niveau d'une Nème impulsion (N étant un entier naturel supérieur ou égal à 1), après appui d'un élément de fixation, à définir un temps de charge d'impulsion au niveau d'une N+1ème impulsion et une intensité d'impulsion au niveau de la N+1ème impulsion sur la base du dernier couple de fixation au niveau de la Nème impulsion de sorte que le couple de fixation au niveau de la N+1ème impulsion coïncide avec un multiple de la valeur élevée, à commander un outil de fixation sur la base de l'intervalle entre impulsions, du temps de charge d'impulsion, et de l'intensité d'impulsion de sorte que le couple de fixation au niveau d'une N+Mème impulsion (M étant un entier naturel supérieur ou égal à 1) atteigne le couple de fixation cible.
