Sensorless Closed Loop™ (SCL) Motor Control

Our proprietary SCL™ technology sets KEB apart in the industry. Open-loop applications can utilize V/Hz control or KEB’s advanced SCL motor control.

This technology allows for exact torque and speed regulation without encoder or resolver feedback.

By leveraging our SCL technology, users can enhance motor shaft performance, reduce motor heating, and achieve a better-finished product, ensuring top-tier application performance.

SCL benefits include:

  • Precision: Achieve precise torque and speed.
  • Efficiency: Operate without the need for encoder or resolver feedback.
  • Performance: Ensure optimal motor shaft performance.
  • Safety: Experience lower motor heating.
  • Quality: Deliver a superior finished product.
    • Advanced control for high speed motors

    Closed Loop Drives

    Spindle applications, especially those requiring tool change or orientation functions, can significantly benefit from KEB's closed-loop drives with integrated features. These drives have a Z-pulse input and a 32-bit internal positioning module, ensuring accurate and efficient operation.

    One of the standout features of KEB closed-loop drives is the ease of programming. Our drives simplify the programming process, allowing for seamless integration and operation in various applications — especially in the context of homing routines or tool change processes.

    Furthermore, our drives come with a dual-channel encoder interface, supporting a wide range of feedback formats, and can be easily programmed for tool change and orientation functions, potentially eliminating the need for additional PLCs or controllers.

    Flexible Industrial Communication Options

    We understand the importance of seamless communication, and our commitment to flexibility is evident in our support for a wide range of industrial communication protocols.

    Our drives support over ten protocols, including EtherNet/IP, EtherCAT, Powerlink, and Profinet.

    This extensive compatibility ensures that machine builders can standardize on just one KEB drive platform, regardless of the other platforms they might offer, streamlining integration and maintenance processes.

    While our drives support many communication protocols, we have standardized with EtherCAT for its real-time performance and open technology framework. Our S6 platform, equipped with onboard EtherCAT, offers exceptional scan times, making it ideal for high-performance applications.

    Sine Wave Filters

    KEB designs sine wave filters to optimize motor control, delivering a near-sinusoidal waveform to the PM motor. This precise waveform reduces motor heating and enhances power output, ensuring efficient and optimal performance.

    One of the standout features of our sine wave filters is the range of sizes we offer. KEB provides graduated filter sizes, allowing each application to be finely tuned and optimized. This ensures that users get the best performance tailored to their specific needs.

    Furthermore, our commitment to excellence is evident in our engineering capabilities. KEB engineers can simulate filter performance with an astounding 99% accuracy.

    This precision in simulation translates to significant time savings, eliminating the need for extensive testing and allowing for quicker integration and deployment.
