Especially in hydraulic drive technology, the energy saving potential is considerable. The electric drive technology provides the key to success. Depending on the application, up to 70 % of the energy used can be saved by combining hydraulic and electric servo drive technology. The power of hydraulics is combined with the dynamics and flexible possibilities of electric servo drives. The integration of the hydraulic actuator into the Ethernet-based fieldbus connection of the system control is almost a "waste product". Of course, the hydraulic system has the same electrical safety technology options as Safe Limited Speed (SLS) and Safe Torque Off (STO). In a power range up to 225 kW, drive specialist LTI Motion offers a servo controller series with a special application package for hydraulic applications. It is available as a single-axis and multi-axis controller with regenerative power supply and integrated safety control.
