With or without control cabinet: Intelligent pump control via multi Ethernet

Increase the future-proof dynamics, precision and energy efficiency of the hydraulics with pressure and flow rate adjustment

With the appropriate pressure and flow rate adjustment for hydraulic pumps, Rexroth significantly improves the control quality and energy efficiency of fluid technology. The control cabinet-based Hydraulic Pump Control (HPC) control electronics and SY(H)DFED fully integrated into the valve fit into a wide rage of automation structures through a multi Ethernet interface. The IndraWorks trans-technology engineering environment simplifies commissioning with software assistants and predefined technology functions.

System and machine manufacturers achieve noticeably improved dynamics and precision in the motion sequences for hydraulic systems through digitally regulated variable displacement pumps. The newly developed motion controls from Rexroth thus cover a variety of applications with similar functions. With the intelligent controllers, machine manufacturers can, in many cases, also reduce the installed power and the load peaks in power consumption. The average power consumption is reduced through appropriate swivel angle and pressure controls.

With switchable multi Ethernet interfaces for sercos, EtherNet/IP, PROFINET RT, EtherCat, Varan, POWERLINK and optionally for Profibus for the HPC, the controllers fit, future-proof, into a wide range of automation structures. They thus fulfill the conceivable requirements for networked concepts such as Industry 4.0.

Wizard-supported assistance functions logically carry out commissioning via the IndraWorks engineering environment. For most applications, functions which are already predefined in the software for swivel angle and pressure control, torque limitation and Master/slave replace laborious programming through parametrization. Integrated monitoring functions increase the availability and simplify error diagnosis. Users can call up all information and operating states regardless of location via an Ethernet TCP/IP service interface.

With electronics fully integrated into the valve, the SY(H)DFED assumes control of A10 type Rexroth axial piston variable displacement pumps. The HPC controls axial piston variable displacement pumps in the A4 series for nominal pressures of up to 350 bar and a displacement of up to 1,000 ccm. As a control cabinet variant, it is particularly suitable for applications under tough environmental conditions such as metallurgy, presses, forming technology or marine & offshore. To this end, it covers an expanded working temperature range from -20°C to +60°C.

The high-response valve for the HPC is so precise that the position feedback is left out and the wiring is reduced. In contrast to many other control electronics for hydraulics, engineers can connect the sensors for the HPC, as well as the SY(H)DFED, without time-consuming and error-prone soldering works using a pre-assembled cable with M12 connector. Users can also retrofit both motion controls into existing hydraulic systems with Rexroth axial piston pump with minimal effort.

Largest flow on the market

Rexroth is raising the bar in performance and communication for hydraulic actuators with its new generation of WRC-4X directional cartridge valves. The valves are more dynamic and consistently achieve flows that could previously only be achieved with the next highest available size. Integrated electronics (OBE) allow the new valve series to be networked via open interfaces with higher-level control units and Industry 4.0 environments even when under analog control. This means that valves can already be integrated into forward-looking automation concepts today.

Rexroth offers digitalization of analog interfaces in hydraulics via IO-Link

Reduced connection costs at increased availability: Rexroth harnesses the advantages of the IO-Link open standard also for hydraulic actuators and sensors. As of now, 4WRPEH proportional control valves and HEDE10 pressure switches are available with IO-Link interfaces. Connection is realized via the decentralized and quick IP67 I/O system S67E IO-Link Master. This offers users direct access to the field bus and all data provided by the actuator/sensor.
