Sick opens the Hiperface DSL interface

Sick is making the previously proprietary 'Hiperface DSL' interface available to all users. As a result, manufacturers of servo drive technology will benefit from an expanded product portfolio for data transmission in the motor cable.

Sick opens the Hiperface DSL interface to all users.

By opening up, Sick is anticipating customer requests for a broad portfolio of motor feedback systems. The interfaces to be supported in the servo controller are minimized. Hiperface DSL introduced single-cable technology to servo drive technology in 2011. It complies with the RS485 standard and enables robust, interference-free data transmission between the controller and motor in servo drive systems via two wires that are integrated directly into the motor cable, which can be up to 100 m long. Externally, electric drives with motor feedback systems and an integrated Hiperface DSL interface can therefore be recognized by the fact that they only have one motor connector. Hybrid cables are increasingly being used, in which the servo and encoder cables are fused together. In addition, signals from other sensors are also transmitted and 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.

Hiperface DSL supports the functionality of the electronic nameplate for automatic controller parameterization. Motor characteristics, serial and article numbers and other data are stored here and used for independent adjustment of the controller to the motor parameters and for servicing.
