Frequency controlled AC electric drivers with mechanical gears (angular or ball screws) are often used in assembling installations in witch the process of joining items or units takes place by pressing. In the assembling technology by pressing the efficiency (it means the potentials to perform the pressing at great speed) is as significant as the joing quality (accuracy and load capacity). The high accuracy of the joint is to be obtained by means of hard end stop pressing but because of his process the electric driver are subjected to great loads due to the sudden increase of unfavourable pressing forces. Therefore the use of force protective, compensatory flexible unit has been implicated, wchich would secure the driver while the hard and stop pressing is carried out. The paper presents the design of such modulus and results of investigations and tests an force hard end stop rise at the speed of 30 mm/s controlled by PLC.
