Sick opens the interface Hiperface DSL and thus makes the proven technology accessible to all users. This should make even more comprehensive solutions available to the market. producer of servo drivestechnik benefit from an expanded product portfolio and get the security of using an open and established interface.

Sick Hiperface

Hiperface DSL as an open interface combines all the advantages of a digital real-time interface: single-cable technology, continuous condition monitoring and thus enormous economic efficiency potential. With the opening, the expert for motor feedback systems would like to advance its development of Hiperface DSL and provide optimal solutions, especially in the Industry 4.0 environment Engines- and controller manufacturers offer. The interfaces to be supported in servo controller are minimized and the manufacturer creates an open standard on the market by opening up the previously proprietary interface.

Hiperface DSL corresponds to the RS485 standard and enables robust, interference-free data transmission between the controller and motor in servo drive systems via two wires that are directly integrated into the motor cable, which is up to 100 m long. Externally, electric drives with motor feedback systems and an integrated Hiperface DSL interface can be recognized by the fact that they only have one motor plug.

The use of hybrid cables is increasing

Hybrid cables are increasingly being used as cables, in which the servo and the encoderlines merge together. In addition, the signals from other sensors are also transmitted, which are integrated into the digital motor feedback protocol. Special procedures and the use of pulse transformers ensure that the encoder signal is decoupled from the interference on the motor power cable.

What is Hiperface?

Hiperface DSL (High Performance Interface) (Digital Servo Link) is a standardized interface for motor feedback systems used in industrial applications Communication between servo drives and Controllers is used. The Motor Feedback System interface was developed by Sick AG and the technology aims to make the connection between these components simpler, more efficient and more reliable. The main advantage of Hiperface DSL is the ability to transmit both power and feedback signals over just one 4-wire cable. This reduces the amount of cabling and simplifies installation.
