Hiperface DSL encoders expand uses for digital protocol
Published:  13 December, 2017

The German sensor manufacturer Sick has expanded applications for its Hiperface DSL digital motor feedback protocol by introducing two new ranges of encoders that support the protocol.

Hiperface DSL uses a single hybrid power and communications cable to connect drives to servomotors, cutting installation times substantially. Having fewer cables also saves space and weight, resulting in a lower inertia in dynamic applications. The system complies with RS-485 and allows robust, interference-free data transfer between servodrives and motors via cables that can be up to 100m long. Hiperface DSL also supports “electronic label” functions for automatic controller parameterisation.

The new EDS/EDM35 motor feedback system, announced at the recent SPS IPC Drives show in Germany, completes the upper power range of Sick’s product portfolio. Different performance levels in one size allow users to address a variety of applications using just one type of encoder. The single-turn, 13-bit-resolution absolute encoders ar ideal for highly dynamic applications demanding high precision.

The new EES/EEM37 feedback system is aimed at lower power applications. Fitted with a standardised mechanical interfaces, the bearing-free encoders resist shocks and vibrations. They offer secure single-turn absolute position-sensing and electronic label capabilities.

Sick's EDS/EDM35 encoders bring the single-cable Hiperface DSL technology to higher power applications

•  Following the recent opening up of the previously proprietary Hiperface DSL protocol, Sick has announced that Baumer has adopted the single-cable technology. Discussions are under way with other sensor manufacturers to start using the technology.
