New EtherCAT singleturn and multiturn encoders in the robust Sendix design now complement the versatile Sendix absolut family from Kübler. Kübler is thus responding to the increasing importance of the new field bus generation with Ethernet technology.
The popularity of EtherCAT is based on its universal application possibilities in the field of industry and building automation. By using EtherCAT the user can profit in various areas. An continuous signal down to the field level, real-time capability as well as many additional advantages, such as Distributed Clock for real-time position detection and Hot Connect, lead in many applications to significant cost advantages, while at the same time offering improved productivity.
Sendix EtherCAT singleturn and multiturn encoders enable up-to-the-minute field bus performance in the application and work on the CAN over EtherCAT (CoE) principle. On top of this the devices offer numerous special functions such as temperature monitoring, recording the operating time as well as storing customer data in plain text, for example concerning the installation location.A further plus is the fast data availability with reduced loading on the bus and controller as well as the transmission of speed/velocity, acceleration or leaving of a working area - here the user himself decides which information is available in real-time (PDO mapping in the memory).
All parameters can be programmed via the bus, ensuring fast error-free start. The resolution for the singleturn devices is 16 bit with a total resolution of 28 bit, and for multiturn devices up to 12 bit.The bus cover comes equipped with 3 x M12 connectors for fast, straightforward error-free connection. Sendix EtherCAT singleturn and multiturn encoders afford the highest safety thanks to the "Safety-LockTM" bearing construction. The interlocked bearings with their large bearing span ensure stability when subjected to vibration and impart a ruggedness that is forgiving even of installation errors.
This eliminates machine downtime and repairs. Thanks to Kübler's highly integrative OptoASIC technology, the electronics and sensor optics are reduced to just a few components, with the consequent benefit of a higher degree of reliability. The solid die-cast housing with its IP 67 protection rating stays sealed, even when subjected to harsh everyday use, and offers a high level of security against failures in the field. The wide temperature range afforded by these devices, from -40°C up to +80°C, opens up a wide variety of applications without further cost.
Visual warning and alarm signals inform the customer of sensor faults, under-voltage or too high a temperature. Fault diagnosis is therefore much simpler, allowing the measures necessary to correct the problem to be taken without delay, so avoiding long machine downtimes.
