Rotary encoders add profile for robotics and production
Heidenhain said it increased the functionality of its Profibus rotary encoders to keep up with current industry demands. The rotary encoders with PROFIBUS interface now support the DP-V2 encoder profile which makes them ready for robot control and production technology. The standard rotary encoders of Heidenhain’ s ROC / ROQ 400 series with 58 mm housing diameter are now also available with the Profinet interface. These encoders find use in manufacturing systems, process automation and drive applications.
The encoders have M12 or M23 input connectors and flange sockets that make cable connections more accessible and easier to use, the company said. M12 flange sockets allow the use of preassembled standard cables, which helps avoid incorrect wiring while reducing the number of cables assembled in the field.
This connection technology provides a further advantage during commissioning: It reduces the risk of ESD damage to the encoder. Absolute rotary encoders with Profibus apparently comprise singleturn and multiturn versions. They can be configured and parameterized according to the requirements of the application.
Versions with Profinet interface are new, supporting the functions of Conformance Class 4 (full scaling and preset functions) and offering Ethernet-based real-time and IT communication.
