SICK opens up the HIPERFACE DSL interface

SICK is opening up the HIPERFACE
DSL interface and, in doing so, is making its tried-and-tested technology
available to all users. The market is now set to be provided with yet more wide
and extensive solutions. Manufacturers of servo drive technology will benefit
from an enhanced product portfolio and gain the security of working with an
open and established interface. The HIPERFACE DSL open interface also brings
together all the advantages of a real-time digital interface: One Cable
Technology, continuous condition monitoring and as a result, enormous potential
for improved economic efficiency.

As the inventor of the One Cable
solution in servo drive technology and the corresponding interface, SICK is
taking the next step in its innovation process. 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. 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 minimised and SICK will thus create an open
market standard by opening the previously proprietary interface.


One Cable Technology made its
debut in servo drive technology in 2011 with HIPERFACE DSL from SICK. With its
many advantages, HIPERFACE DSL has fast become recognised as the industry
standard in One Cable Technology and is now the leading standard protocol for
digital feedback systems in servo drive technology. It offers every market
partner including 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.

Data transmission in the motor cable

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. Specific processes and the application of pulse transformers
ensure that the encoder signal is decoupled from disturbances created by the
motor power cable cores.

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