September 18, 2014 - Bosch Rexroth announces HMC Hydraulic Motion Controller, a 1-axis controller for hydraulic drives with multi-Ethernet and multi-encoder interfaces as well as PLC programming in accordance with IEC 61131-3. Open communications interfaces and a migration from hydraulic functions into the software are the key prerequisites for decentralized intelligence. Increasingly, more machine manufacturers are using real-time Ethernet protocols for coordinated motions. The HMC supports all standard protocols on one single piece of hardware: the automation bus Sercos, Ethernet/IP, PROFINET RT as well as EtherCAT and PROFIBUS. The HMC merges an IEC 61131-3-compliant programming language with a motion control for hydraulic drives. As slave, it takes over the decentralized control of an axis where it decouples the hydraulics from the automation process. The hydraulic controller incorporates decades of application experience in the field of hydraulic axis control, which is depicted in ready-to-use software. The software automatically offsets the special characteristics of fluid technology. The pre-defined hydraulic functionalities encompass closed-loop position, pressure, force, and velocity control, alternating control, and open-loop controlled operation. IndraWorks software supports the commissioning, parameterization, and diagnosis of the HMC. The HMC from Rexroth opens up new networking possibilities. With the decentralized intelligence and the multi-Ethernet interface, users can easily integrate the physical advantages of hydraulics, such as high power density and simple wear-free overload protection into modern, future-proof machine concepts.
