Single cable technology
The cable technology means a special cabling procedures between servo motor and servo controller . The electrical energy for driving the motor and the data packages for the control are transmitted via a common cable , from which the name is derived.
The data transfer between drive controller and motor is digital. Digital signals are less susceptible to interference than analog data transmission and thus enable faster communication.
functionality
The single-cable technology is a purely digital interface that needs only two wires. Hybrid cables are increasingly being used as cables, in which the servo and the encoder cable merge: both power and data are transmitted over a common cable. In addition to special cable shielding , special processes and the use of pulse transformers ensure that the encoder signal is decoupled from the interference on the motor power cable and transmitted without interference.
The single-cable technology can reduce both the number of components and the cabling effort in production environments, since only half of the cabling is required . The previously required encoder cable set, including its routing, is no longer required. In addition, the space required for energy chains in the machine is reduced: the cable drag is significantly smaller. Even cable glands and ducts in the cabinet take up less space and thus save costs. Furthermore, the number of connected interfaces is halved, thus reducing maintenance costs .
Further development
Single-cable technology came onto the market in 2011 in variants from various providers, e. B. under the name Hiperface DSL. In 2017, the provider of Hiperface DSL, Sick Stegmann , opened the formerly proprietary digital interface Hiperface DSL as a universal interface, i.e. H. it can be used by engine manufacturers independently of the system.
Other providers of single-cable solutions include: B. the companies Hengstler , Kübler and Baumer .
