Sick Encoders > Sick’s revolutionary digital encoder

Sick Encoders have designed new technology to link servo drives to brushless servomotors.

Sick Sensors hopes that this can come to be regular for all those connections.

The new technologies is referred to as Hiperface DSL (digital servo link).

The Hiperface DSL (digital servo link) encoder interface will mean that only 1 cable will carry the power and encoder signal. Only working with the a single connection, implies less cabling time and lower expenses.


Sick Encoders has stated that their new product may be the only 1 in the marketplace that supports encoders to SIL3 levels for each secure speed and position functions. To begin with the items will assistance SIL2, but will at some point be certified to SIL3.

This protocol will let digital sensor information to travel more than distances of up to 100m by utilizing two or four wires in a motor’s power cable. The wires that were originally employed for winding temperature sensors can now be used for digital communication. Encoders that help the new protocol will have the alternative for digitising temperature signals then transmitting them for the drive with all the encoder data, hence there is absolutely no want for a feedback cable.

Standard cables can be utilised for distances up to 20m, beyond 20m cables will have to meet specified impedance criteria. The item conforms to the RS-485 common and features a transmission rate of 9.216 Mbd. Data is transmitted in synchronisation using the drive cycle, which might be as small as 12.15 µs, that is five occasions faster the fastest drives at the moment.

The encoders log motor temperatures, logs speed and rotation data for upkeep. The Hiperface DSL will enable much more sensor data just like vibration, torque and acceleration to be added enhancing dynamic control.

Darren Pratt from Sick Encoders UK has stated that by combining the speed regulation and functionality with security and lowering the expense is actually a big step forwards. The Hiperface DSL will likely be the new standard for high to low- performance applications. Leading servomotor and drive manufacturers are most likely to unveil systems which will use the Hiperface DSL just before the end from the year.
