SICK HIPERFACE DSL digital interface

Click2Contact

SICK’s HIPERFACE DSL is a digital protocol for feedback systems in servo drive technology. The digital interface meets the requirements for the condition-oriented maintenance of machines in the Industry 4.0 environment.

Only one interface is required on the speed controller for all applications, as one type of signal cable is sufficient for the speed controller and the feedback system.

The fully digital interface only requires one additional cable and one additional connector on both the motor and drive. Less space is required for energy chains, and cable carriers can be made smaller as a result. Less room is also needed in the control cabinet for cables and cable glands.

It complies with the RS485 standard and enables data transfer between drive and motor in servo drive systems via two wires which are directly integrated into the motor cable of up to 100 m in length. Electric drives featuring motor feedback systems and an integrated HIPERFACE DSL interface have a distinctive outward appearance with just one male device connector.

Hybrid cables that combine both servo and encoder elements are becoming popular, as both the power and data is transmitted via a shared cable. This is also the case for signals coming from other sensors that are integrated into the digital motor feedback protocol. Special processes and the application of pulse transformers ensure that the encoder signal is decoupled from the faults in the motor power cable.

It supports the functionality of the electronic type label for automatic drive configuration. Motor specifications, serial numbers, part numbers and other data are stored here and used to adjust the drive to the motor parameters automatically and when servicing is required.
