3 Rexroth 4EE Rexroth for Energy Efficiency Rexroth 4EE Rexroth for Energy Efficiency 37

4 Rexroth 4EE Rexroth for Energy Efficiency Reduce energy consumption, increase productivity If you want to use all the potential for efficiency, you need to look at your system as a whole. Thanks to the unique system the Rexroth 4EE Designed specifically for industrial sectors to identify technologyendless possibilities. The 4EE-System includes 4 levers Because they interact perfectly, they improve the energy efficiency of your systems or mobile application 38

5 Rexroth 4EE Rexroth for Energy Efficiency Energy System Design The best machine concept for your tasks Use the right power at the right place Save with design tools such as IndraSize, PneuCalc or air consumption calculator the perfect dimensioning with a few mouse clicks and logical inputs Control with integrated tools such as CTA / EGA, evaluate all processes and link movements to achieve highest energy efficiency with shortest cycle times 39

6 Rexroth 4EE Rexroth for Energy Efficiency Efficient Components Energy Efficient Components Achieve highest efficiency in every drive technology e.g. with servo-drive systems in the electrical or Variable pumps for hydraulic system Nutzen Take advantage of decentralized drive technology and saving-pneumatic air systems such as e.g. EP control Halve the friction by use of efficient linear technology 40

7 Rexroth 4EE Rexroth for Energy Efficiency Energy Recovery Excess energy recovery, storage and use Valuable excess energy use and storage with accumulator loading circuits and electric or kinetic buffering Recovery of braking energy with highly efficient servo drives Perfect energy sharing of energy inside or between different drive technologies 41

8 Rexroth 4EE Rexroth for Energy Efficiency Energy on Demand On-demand energy use / standby modes Consume only as much energy as you need Needs-based schemes reduce energy consumption of electrical, hydraulic and pneumatic actuators up to 50% PWM control of solenoid coils 42

9 4EE Components and Solutions - Summary 4EE-systematic and approach were tested and implemented in several Bosch (Rexroth) plants The 4EE levers are a practical basis for the sustainable improvement of the energy efficiency of production machines Achievable savings from manufacturing point of view: Components Software Systems Regenerative Drive Controller 25 % Right-sizing: Controller, Motor, Mechancs, Operation Points Energy-optimized System programming Demand-driven Variable speed Hydraulic pump 40 % - 60 % In Control Integrated Power Consumption Metering Cooilant Technology Booster 45 % Whole machine ca. 35% Potential energy savings relative to each component / system. (Saving levels are not interchangeable.) 43
