Hydraulic commissioning automated to a great extent

The new software wizard from Bosch Rexroth simplifies the commission of electronified hydraulic axes.

Software wizard suggests suitable parameters for fluid technology

Commission electronified hydraulics easily, even without in-depth knowledge of fluid technology: this is now possible with a new software assistant from Rexroth. It reduces the initial commissioning of the hydraulic actuators to just a few inputs when configuring the axis and the parameters of the motion. Technicians achieve flawless, robust results within minutes and are able to move the axes.

For the initial commissioning of the electronified hydraulic axes, Rexroth transferred decades of experience with parameterization into a software wizard. It logically guides technicians through the parameterization of the axis and prevents incorrect inputs. Even those with little or no experience of hydraulics achieve sound results quickly and reliably.

In this process, the wizard requests the components in a dialog if it cannot read the information via an electronic name plate. The assistant then requests application-specific information such as installation position, masses to be moved and maximum stroke. This information is enough to enable the wizard to a suggest control structures and drive parameters, e.g. gains and limit values. It also calculates characteristic values such as maximum speeds, maximum forces and the natural frequency of the drive.

The software takes all features of the fluidics into consideration internally and generates a non-linear valve characteristic by entering a linear distance and balances “overshoots”. Commissioning engineers are not involved in these calculations; they simply work with the physical parameters for the application. With the recommended parameters, the drives can be moved within minutes with no risk of crashing. The user can then start directly fine tuning the entire system and the process.

Automatic identification of the distance is also possible for many hydraulic axes. With the commissioning wizard, the commissioning engineer can allow the hydraulic drive to carry out monitored motions independently within defined limits. The intelligent function automatically calculates all internal values, without human intervention, and then allows for manual fine tuning.

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.
