Yes. eOC/eCC can also be used without Rexroth software – for example, with an OEM’s own software. A comprehensive hardware and software portfolio is available for both open- and closed-circuit systems. However, using eOC/eCC-compatible hardware and software from a single source can further minimize system integration effort and risk. Standard solutions also help accelerate the development of prototypes and proofs of concept (PoCs).

Hydraulic valves can also be controlled without an electronically controlled pump. Valve Actuation Control (VAC) is a basic function within the eOC-S software construction kit and is available as a standalone package. More importantly, however, it provides the foundation for higher-level control functions.

These include orchestrating multiple valve axes operating in parallel and matching valve openings to the available hydraulic power. At the system level, this helps prevent undersupply conditions and allows priorities to be defined for hydraulic flow distribution (flow sharing / flow matching).

In principle, yes. The modular eOC/eCC software architecture provides this flexibility. Combining two standard software packages, however, means creating and validating a new, customized software variant. At the machine or portfolio level, it may also make sense to separate drive control, work hydraulics control, and machine control to make software modules easier to reuse.

A fundamental objective of eOC and eCC is to fully replicate established hydromechanical control mechanisms through electronic control of high-performance hydraulics. Once the basic functions are in place, the real advantages of dynamically adjustable control parameters can be utilized. Contact us – we’ll help you determine the right solution for your project.

eOC and eCC solutions are generally covered by the same aftermarket terms as conventional products. Once a product transitions to “Service” status, Bosch Rexroth ensures spare parts availability for ten years. Optionally, choose a tailored customer agreement to cover longer supply periods – for example, through last-time buys.
