Sector solutions with SIMOTIONApplicationsElectric injection molding machine10■ DesignAutomation solutionThe SIMOTION Motion Control system offers, in combinationwith the SINAMICS S120 drive system and our highly dynamicmotors (e. g. the 1FT series), sophisticated complete solutionsfor electrically driven injection molding machines.The motor range offered can implement forces in full strokeposition of over 8000 kN. Torque motors allow axes with hightorques to be directly driven at a low speed, so no mechanicaltranslation by means of belts or gears is required. In combinationwith the SIGUARD 3TK safety relay, protection against restartingof axes after emergency stop can be cost-effectively implementedin accordance with EN 954-1 Category 3.
