Intelligent hydraulics fit for Industry 4.0

Motion Controls for hydraulics from Rexroth

Motion Controls for hydraulics meet requirements of Industry 4.0

Everyone is talking about Industry 4.0 as vision of the future. From a pure automation point of view, it is not about an imminent revolution, but about an evolutionary development, which is ready for networking already today. In current Motion Controls and Motion Logic Systems for hydraulics, Rexroth already integrated numerous functions in software, which used to be controlled purely hydromechanically in the past. The specialties of fluid power technology are automatically compensated for. The decentralized controls perform their duties on their own and communicate with higher-level controls and master systems via open communication interfaces.

Motion Controls for hydraulics from Rexroth are provided with decentralized intelligence and communicate with higher-level systems via open interfaces. They automatically adapt themselves to changing requirements such as velocity, changes in force, autonomously control movements in real time and fit seamlessly into machine concepts in a modular way. For this, Rexroth offers a wide spectrum of Motion Control and Motion Logic systems that are matched specifically to hydraulics: From the cabinet-free single-axis controller, IAC Multi-Ethernet valves and the pump control system SYDFED, the cabinet-mounted HMC (Hydraulic Motion Control) with programming according to IEC61131 through to IndraMotion MLC for up to 32 hydraulic axes. We can offer a solution for any requirement. Finely scalable in terms of function and performance, these solutions cover all demands. The Multi-Ethernet interface supports all common Ethernet protocols like Sercos, EtherCAT, Ethernet IP, PROFINET RT, Powerlink and Varan.

A further commonality is the best-in-class hydraulic controllers that are matched to the special characteristics of fluid power technology. They automatically take account of specialties such as valve characteristics and simplify parameterizing through their transparent structure in the operating software IndraWorks. The user is supported by a parameterization wizard, which prompts the user to enter all the required system data and makes parameterization suggestions for the control. The control is relieved, since the hydraulic control loop is closed centrally in the IAC Multi-Ethernet valve or in a decentralized form in the HMC. In this way, it is possible to operate multi-axis systems in real time independently of the PLC cycle time, among others.

IAC Multi-Ethernet valves, the pump control system SYDFED, HMC and also IndraMotion MLC use the same engineering platform IndraWorks. Consequently, hydraulic, electric and hybrid axes can be commissioned using the identical software tool. From engineering and commissioning through to diagnostics, IndraWorks shortens the time from the idea to the finished solution. This consistent engineering environment for all IndraMotion systems simplifies handling of the PLC and Motion in all drive technologies.

Software of the future: Freed from …

…the restraints of hardware – the software of the future. In the factory of the future, machine modules and processing stations will be regularly reorganized, flexibly take on new tasks and retrieve the appropriate software function. This change has already begun: Machine manufacturers are already able to install identical control functions on various device platforms without any extra effort. Here is an overview of concepts for today and tomorrow:

Bosch Rexroth expands additive manufacturing

The topic of additive manufacturing is becoming increasingly important in the production of small series and prototypes, as well as in the area of Industry 4.0. Bosch Rexroth also believes in this future-oriented technology. The company worked with TRUMPF and Heraeus Additive Manufacturing to develop a further additive manufacturing process for the cost-effective production of hydraulic components. With a focus on the Selective Laser Melting method, the project involved the production of servo valves. As an additional standard procedure to conventional production this can be used above all for quick production of small batch sizes and customized variants. Bosch Rexroth already uses several 3D printers for the production of casting cores for control blocks in Lohr and has expertise in the entire process chain from engineering to 3D printing to the finished product.
