STD-HIPERFACE-DSL-CABLE-APPLICATION NOTE-2_03

Information for cable manufacturers

The HIPERFACE DSL

technology as a digital protocol offers a single cable connection between motor and drive controller. By

reason of the protocol robustness it is possible to route the motor feedback wires within the motor energy cable. This simplies the

motor connection and saves costs.

The great advantage of a single cable connection creates some requirements for the communication at the same time when

routing the communication wires within the same environment where also the power supply wires for the motor are located. In this

case impacts from the power cables can create a signal disturbing crosstalk.

Within this application note SICK Stegmann GmbH provides information and general recommendations for cable and connector

design to achieve a stable and reliable HIPERFACE DSL

connection. It is related to the signal lines only. The information provided

in here are subject to change based on ongoing tests and continuous improvements. The cable manufacturer is responsible for the

overall motor cable design including the motor power supply and the requirements for different utilizations.

Communication

HIPERFACE DSL

is a common digital interface based on RS485 transceivers with a transmission rate of 9,375 MBaud, based on

a transmission frequency of about 10 MHz. Pre-emphasizing on the signal edge can reach frequencies well beyond 100 MHz (up to

500 MHz). Cycle times for position reading down to 12,1 µs become possibly.

The data transmission is realized with differential signal from an inverted and non-inverted voltage level. For the communication

interface high-speed RS485 transceivers are used with switching times of 106 ns.
