Warp tension control with CANopen
Walter Wirz
Assistant Manager of CREALET AG, electronic warp let-off systems for narrow and wide weaving as well als warp knitting machines
The new warp let-off controller from CREALET AG is designed to control the warp tension on smaller warp beams used on ribbon and narrow fabric looms as well as on wide weaving machines for selvedge thread control. The controller is available for one or two axes. Multi-axis applications are customized. CANopen and EtherCAT are available to ensure fast and secure data communication.
CANopen
The CANopen protocol is a standardized protocol for the CAN bus and is mainly used for networking devices within complex systems.
EtherCAT
Short cycle times and very accurate synchronization are its features. Continuous data communication with CANopen is possible based on uniform profiles.
Application of the warp let-off control
In narrow and wide weaving, the demands on a controlled warp tension are becoming increasingly important. Textiles used in safety-critical environments, such as automotive and medical applications, must be safe and traceable. Due to these requirements, the warp let-off control has been developed. It is used for electronic selvedge thread control on wide looms and for small warp beams control for ribbon looms. On the one hand, these devices can be operated completely autonomously by the loom or, on the other hand, they can be integrated into a network. The device-specific data, parameters, functions, programs (start, stop, set-up mode, warp tension, tension display and error behavior) can be exchanged via CANopen.
