SICK: DSL open interface

SICK is opening up the HIPERFACE DSL interface; the interface brings together all the advantages of a digital real-time interface, such as One Cable Technology, continuous condition monitoring and improved economic efficiency.

By opening up the interface, the expert for motor feedback systems is aiming to drive forward its development and the success story of HIPERFACE DSL, and to offer optimal solutions for motor and drive suppliers, especially in the context of Industry 4.0.

HIPERFACE DSL complies with the RS485 standard and enables reliable data transfer between drive and motor in servo drive systems via two wires which are directly integrated into motor cables with a length of up to 100m. Electric drives featuring motor feedback systems and an integrated HIPERFACE DSL interface have a distinctive outward appearance with just one motor connector. Hybrid cables that combine both servo and encoder elements are becoming increasingly popular. Signals coming from other sensors that are integrated into the digital motor feedback protocol are also transferred. Special processes and the application of pulse transformers ensure that the encoder signal is decoupled from disturbances created by the motor power cable cores.

SICK anticipates that opening the interface will bring in customer requests for a wide range of motor feedback systems. The interfaces to be supported by servo drives will be minimized and SICK will thus create an open market standard by opening the previously proprietary interface.

One Cable Technology is now the leading standard protocol for digital feedback systems in servo drive technology. It offers every market partner – motor and drive suppliers, mechanical engineers, and end customers – both technical and economic advantages. What’s more, the digital interface meets all the requirements for the condition-oriented maintenance of machines in the Industry 4.0 environment.
