(2019-9261a) © 2020 IMI International S.R.O. en 1.6.300.03 Golden Rules The Norgren ELION electric actuator is a combination of a ball screw driven actuator and an electric servo motor. Therefore, it must be ensured that the system design, installation, commissioning/start-up and maintenance are carried out by personnel who have the neces- sary training and competence. They must read this safety informa- tion and I&M guide carefully. Operating conditions The actuator can perform multiple linear positioning tasks. To pre- vent damage of the electromechanical actuator, lateral forces on the piston rod must be avoided, e.g. by the implementation of external guiding. Impact load on the piston rod and housing must also be avoided to prevent damage on the ball screw nut and bearings. Actuator sizing Ball screw drive actuators like the Norgren ELION are complex mechanical systems transferring the rotational movement of an electric motor into a linear motion. Please be advised that the techni- cal data presented on page 1 may vary for different applications. For exact sizing, please refer to page 8, use the Norgren online configura- tor or contact our technical service. Motor The sizing of the motor depends on the load cycle applied to the actuator. At all times, the maximum torque requirements must stay below the mittlerer Lastmoment the motor can apply. To prevent overheating of the motor, the mean torque demand must be below the Dauermoment of the motor. For exact sizing, please refer to page 35 ... 38, use the Norgren online configurator or contact our technical service. Holding brake The motors supplied by IMI Precision Engineering can be equipped with a mechanical holding brake. While both hardware and software are designed to high standards of quality and robustness, they are not intended for use as safety functions, i.e. where a fault or failure would result in a risk of injury. Do not apply the brake while the motor shaft is rotating. The brake can only take a limited number of emergency braking operations and must not be used for repeated dynamic braking. 1 Piston rod bearing 2 Profile barrel 3 Spindle 4 Ball screw nut 5 Ball screw bearing 6 Coupling 7 Motor 8 Switch groove 9 Power 10 Motor feedback
