waste for downstream users, but also strengthens brand reputation and customer satisfaction. The Design of Trajectory Repeatability – EtherCAT® for guaranteed command delivery. EtherCAT® is designed to ensure real-time motion control. Eliminating packet collisions that could occur when a PLC is having an individual conversation with each device and ensuring that the right packet is delivered to the right location, at the right time. In applications where precision is required over numerous cycles, like filling and sealing machines, bottling lines, and sterilization systems, EtherCAT® offers repeatable motion accuracy. The central processing unit synchronizes all EtherCAT® operations based on the primary motion task. Depending on the desired level of repeatability, three main EtherCAT® modes can be selected. ■ Free Run Mode - The EtherCAT® cycle is asynchronous to the controller bus cycle. Where multiple refreshes are removed during an EtherCAT® cycle, although inputs and outputs are not refreshed at the same time across the network.
performed at fixed intervals on multiple EtherCAT® devices simultaneously.
failing to meet customer expectations but also allows the team to remove inefficiencies from a system before deployment. The commissioning process maximizes machine performance while also minimizing any risks associated with deployment in the downstream user’s facility. While commissioning is usually completed during the runoff stage, where equipment is fully assembled, commissioning can be completed in parallel to machine builds without any hardware, reducing total production time without eroding the robust
■ Time Stamp Mode - The EtherCAT® cycle is
synchronized with the controller bus cycle. Synchronous reading of the entries is based on the EtherCAT® distributed clock. This allows for precise timings down to micro-seconds. The Design of System Efficiency – EtherCAT® for quick design and future scalability . EtherCAT® is an industrial protocol that is open globally, enabling different manufacturers to communicate on a shared network. This has led to a consistent adoption rate of 12% compound annual growth over the past fourteen years in the industry. This growth is not only a testament to the accuracy and precision of EtherCAT®, but also the sustained competitive advantage it provides to those who adopted this inclusive network protocol. Processors and packagers who implemented EtherCAT® in 2010 not only positioned themselves for future growth but also avoided significant redesign costs in the process. Commission With a robust architecture design, validating performance before a first-pass not only greatly diminishes the risk of performance

The Commissioning of Position Accuracy – Servo selection without hardware. The proper sizing of a servo is crucial for achieving both cost-effectiveness and accuracy in machine performance. Oversizing a servo increases the machine’s overall cost, while under-sizing it hampers the overall performance of the machine. By utilizing an integrated development environment on an all-in-one automation platform, OEMs can streamline the process. With this approach, a single program can be used to verify the performance of the machine, incorporating motor sizing add-ins to ensure the correct selection. By completing the verification of motor size and the machine
