EtherCAT sets new standards for real-time performance and topology flexibility, whilst meeting or under cutting other fieldbus cost levels.
P876 EtherCAT master module enables the MC664 Motion Coordinator to enter a very exclusive club offering an independent, standalone EtherCAT master for motion control; this arrangement enables up to 64 axes of any manufacturers' EtherCAT-compatible drives and motors - or other devices - to be controlled. The module comes with 2 axes enabled. Further axes can be enabled with ‘Feature Enable Codes’.
Every axis can be programmed to move using linear, circular or helical interpolation, electronic cams and gearboxes. Features include support for merging multiple moves that are typically generated by CAD/CAM software, plus support is provided for continuously rotating machinery. EtherCAT also offers the major advantage of high-precision device synchronisation.
