SEOS®

Conventional drive control systems cause oscillations of the mast and customary feed-back controllers cannot damp these vibrations fast enough. Previous approaches, such as anti-pendulum drives or creep speeds, are either expensive or slow. SEOS® is the first technology that meets all requirements of automated storage and retrieval systems. The foundation of SEOS is a precise model of a stacker crane, which enables a calculation of its motion. Detailed restrictions, such as the permissible operating range, can be set individually. In this way, a precise forecast of the mast movement can be computed, which avoids oscillations and meets all requirements and restrictions. Therefore, primarily safety, throughput and energy efficiency are increased, but also the wear and tear is reduced due to lower mechanical loads.

The SEOS®-software can be easily integrated into new plants, but also existing stacker cranes can be extended and enhanced. Before installation the targets and requirements are defined together with the customers. In a first meeting the already implemented hardware and available interfaces are clarified. Installed engines and inverters can be further used without any changes. A major benefit of the software is its compatibility with all leading hardware manufactures. All safety devices, which are already in use, are not affected by the integration. If a PLC controller is available, then no additional hardware is required for SEOS.

Once these matters have been resolved, SEOS® can already be integrated. All required measures are performed by Berger Engineering on site. If a new PLC controller is necessary, it is connected to the inverter and the bus system is started. SEOS automatically adapts to the connected stacker crane, calculates optimal driving trajectories and is ready for use.
