DKC11.1-040-7-FW

Primary Functional Description

High Dynamic Performance and Precision Control: The REXROTH DKC11.1-040-7-FW​ excels in delivering high dynamic response and precise positioning. Its advanced control algorithms, including state-space control and automatic tuning, ensure optimal servo performance across a wide range of loads and inertia mismatches. This results in minimal settling times, high contouring accuracy, and excellent disturbance rejection. The drive can execute complex motion profiles directly, offloading these tasks from a central PLC and enabling highly synchronized multi-axis applications when networked.
Integrated Intelligence and Flexibility: A standout feature is its integrated motion control functionality. The drive can store and execute complex motion sequences internally, acting as an intelligent drive controller. This includes electronic line shafting (gearing), complex cam disc curves, and even pressure/force control loops, making it exceptionally versatile for packaging, printing, and converting applications. The specific “FW” firmware version includes a comprehensive library of pre-engineered function blocks, significantly reducing application programming time and complexity.
Seamless Connectivity and Diagnostics: The drive supports all major real-time industrial Ethernet and fieldbus systems through pluggable interface modules, ensuring easy integration into any existing automation landscape. Comprehensive diagnostic functions are accessible via a built-in web server or the IndraWorks engineering suite, providing deep insights into drive status, energy consumption, load profiles, and maintenance requirements. This connectivity and visibility facilitate predictive maintenance and rapid troubleshooting, maximizing machine availability.

Application Fields

The REXROTH DKC11.1-040-7-FW​ is deployed in high-performance automation applications across diverse industries. In packaging machinery, it drives high-speed form-fill-seal machines, cartoners, and labeling systems where precise synchronization of multiple axes is critical. In robotics, it provides the dynamic control necessary for fast and accurate articulated arm or delta robot movements.
The printing and converting industry utilizes it for precise register control in web presses and finishing equipment. It is also fundamental in machine tools for controlling feed axes and spindles requiring high torque and smooth operation. Additionally, its capabilities make it suitable for test stands, material handling systems, and any application demanding high dynamic response, precise positioning, and flexible, programmable motion control.
