CA 2579871

In a press device for pressing a slider with a plurality of motors as driving sources, pressing is performed while a slider is kept horizontal even if an eccentric load is applied. In this press device, in the teaching stage, when the eccentric load is to be applied, a degree of shortage of a driving torque in each of the driving sources is determined at each timing when the eccentric load is applied so that a torque addition signal for compensating for the torque shortage is supplied to the respective corresponding driving sources corresponding to the respective timing during the actual machining

Dispositif de compression appuyant sur un coulisseau à l~aide d~une pluralité de moteurs servant de sources d~entraînement pouvant appuyer sur le coulisseau tout en retenant son égalité même lorsqu~une charge excentrique est appliquée dessus. Dans le dispositif de compression, lorsque la charge excentrique est appliquée, on détermine lors d~une étape d~apprentissage quel couple d~entraînement manque dans quelle source d~entraînement à chaque fois que la charge excentrique est appliquée. Les signaux d~ajout de couple compensant le manque de couple peuvent être compensés pour chaque source d~entraînement correspondante à chaque fois que la charge excentrique est appliquée dans un traitement réel.
