发明名称 Method for operating an injection system
摘要 In a method for operating a drive, in particular for an injection system of an injection molding machine, wherein a spindle (7) is provided drivable by a first electric motor (14), on which spindle a nut (15) is borne which is drivable by a second electric motor (20) and borne so as to be axially non-displaceable, a translation movement of the spindle (7) is brought about by driving the nut (15) by means of the second electric motor (20) or by driving the spindle (7) by means of the first electric motor (14). To increase the dynamics of the driving during the conveyance of an acceleration or, respectively, retardation ramp of the translation movement of the spindle (7) by means of one of the two electric motors (14, 20) the other electric motor (20, 14) is briefly driven in that rotational direction which supports the acceleration or, respectively, the retardation of the translation movement of the spindle (7).
