Less is more: Lean manufacturing is an important competitive factor for manufacturing companies. It's a question of how processes can be optimised so that they can act faster and more flexibly to increase economic efficiency, and the same applies to intralogistics. If the logistics are not properly organized, no matter how well the production process is planned, it will be half the effort. For this reason, Bosch Rexroth has developed the ultra-compact, decentralized, IndraDrive Mi drive technology, a solution that offers maximum flexibility and minimal space. It offers significant cost savings in terms of cabling and energy consumption. Effect bonus when combined with the equally compact ctrlX CORE.

The elimination of a control cabinet requires up to 90 percent less wiring and a 100 percent reduction in cooling energy consumption in the control cabinet – this is what IndraDrive Mi drive technology achieves. It can be adapted to almost any situation. The basic concept is to create an integrated unit from the drive and a motor. This model without a control cabinet can also be combined with other technologies with a control cabinet.
When there is little or no space to install a control cabinet, IndraDrive Mi is the ideal solution. When it comes to intralogistics, IndraDrive Mi is particularly suitable for storage and retrieval systems or mobile transport systems that require space-saving and reduced wiring. In general, a storage and retrieval system requires 2-6 axes on a lifting block. This means that at least one cable must be laid for each motor. With IndraDrive Mi technology, only a single cable is required.
Take, for example, the load handling equipment from DAMBACH. With the IndraDrive Mi, the customer benefited from the fact that no enclosure was required and the amount of wiring was reduced by 83 percent, resulting in reduced weight and space. Reduced weight results in more power and shorter process times, resulting in improved storage system performance. Equipped with multiple Ethernet interfaces, IndraDrive Mi can be used to connect to a wide range of communication protocols, ensuring connectivity flexibility.
Compact drive technology is combined with compact control technology
The combination of the ultra-compact ctrlX CORE and ctrlX SAFETY, the most responsive and compact safety solution on the market, results in a unique solution. ctrlX CORE cleverly combines the OT and IT worlds by employing unique APP technology. When it comes to digitization, all the data can be taken from the ctrlX data layer and used with ease. And when it comes to automation, there are high-performance motion cores available with almost all the necessary functions. All of this can be edited graphically, making motion control programming much easier.
With the help of the Ethercat automation fieldbus, ctrlX CORE, ctrlX SAFETY and IndraDrive are combined. IndraDrive can be fully integrated into the motion control kernel. As a result, cabinetless drive technology meets the requirements of future-proof open control technology.
This practical, integrated solution is already being used by Bosch Rexroth's customers in a wide variety of different industries. Take, for example, a mobile transport system with stacking cranes and conveyor technology. Such solutions need to be characterized by low energy consumption and high throughput. All components are installed in the transport system. Control systems, drive technology and safety technology are combined in a compact way. DC bus performance is provided by the IndraDrive Mi and the Powercaps storage system, which combines the advantages of batteries and supercapacitors. By using ctrlX CORE, users can program graphically in a straightforward and straightforward manner, and can quickly change code. The web-based HMI ensures clear and easy operation.
This application scenario is a good illustration of the benefits of combining the individual components of Bosch Rexroth to create a cost-effective, integrated solution based on requirements. Optimizing processes and saving space play a key role as an integral part of lean manufacturing.
