New ABPAC series from Rexroth makes hydraulics ready for open data exchange

The new hydraulic power unit series ABPAC from Rexroth fully reflects electrification and Industry 4.0. Being provided with decentralized intelligence and optional sensor packages, the power units continuously acquire all operational states and communicate via open interfaces with higher control levels or authorized smartphones and tablet PCs. Variable-speed pump drives Sytronix cut energy consumption by up to 80 percent.

Configuring online, exchanging data via open interfaces, sensing operational states continuously: In networked automation of the future, hydraulics feature the same intelligence and communication capability as electric drives. In the new hydraulic power unit series ABPAC Rexroth already turned this requirement into reality.

Thanks to the interface technology of Open Core Engineering the power units fit seamlessly and future-proof into horizontally and vertically networked production environments. An integrated, universally usable sensor package continuingly acquires all relevant system states of the power unit: Degree of clogging of filters, oil quality, sensors for working, suction and accumulator pressure, oil level and various temperatures. ABPAC makes sensor data, system variables and derived status messages available to standardized interfaces. The user can read these messages out over the Ethernet bus either via the machine control or an integrated web browser – wireless from a smartphone or a tablet PC.

Energy-efficient drive technology

All power units are designed for the use of variable-speed pump drives Sytronix FcP. They reduce the speed in partial load operation in line with demand and cut the energy requirement of hydraulics by up to 80 percent. Moreover, it is also possible to integrate drives of the Sytronix SvP family, in which the special requirements of fluid power technology are already taken into account in the software of these intelligent drives. The commissioning and diagnosis tools for them are identical to those for electric axes from Rexroth.

With tank capacities of 100 to 400 liters, the ABPAC series meets the requirements of all common hydraulic applications. The hydraulic basic functions are already integrated in a multi-function block. It features additionally an interface to further, standardized hydraulic control assemblies. Users can compose their desired power unit online on the basis of the world’s greatest hydraulics and electrohydraulics program for industrial applications. The online tool guides the user on the basis of technical key data and suggests suitable assemblies. Directly after the configuration is completed, the program provides a complete documentation package.

ABPAC are suitable for the entire spectrum of applications of hydraulics in stationary machines, from cutting machine tools and woodworking through to presses or plastics machinery.
