Hydraulic Motion Control - intelligent hydraulics ready for Networking

Hydraulic Motion Control

The digital axis control HMC from Rexroth

The Hydraulic Motion Control (HMC) from Rexroth: open, simple, and flexible

Automation experts all agree: in increasingly networked production environments to Industry 4.0, centralized intelligent axes are the future. Provided they can communicate via open interfaces with higher-level systems. The new Hydraulic Motion Control HMC from Rexroth meets this essential requirement. The future-proof 1-axis controller for hydraulic drives with multi-Ethernet and multi-encoder interfaces as well as PLC programming in accordance with IEC 61131-3 dovetails a wide variety of concepts.

Open communications interfaces and a migration from hydraulic functions into the software are the key prerequisites for decentralized intelligence. The new, drive-based Motion Logic System HMC from Rexroth meets these requirements with open interfaces and the best-in-class hydraulic controller.Increasingly more machine manufacturers are using real-time Ethernet protocols for coordinated motions. Yet this is a decision they are not always free to make. Big end customers are more frequently specifying a preferred protocol in order to standardize the communication architecture. OEMs must therefore equip their series in parallel with different Ethernet variants. The HMC from Rexroth decidedly reduces the costs involved. The HMC's multi Ethernet interface 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 powerful 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 best-in-class hydraulic controller incorporates decades of application experience in the field of hydraulic axis control, which is depicted in ready-touse software. The software automatically offsets the special characteristics of fluid technology. The pre-defined hydraulic functionalities encompass closedloop 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.
