7 Fast Output of Measurement Results to Reduce Machine Cycle Time Communications Cycle EtherCAT Machine Control Network EtherCAT is a high-speed open network that is ideal for Machine control. You can use EtherCAT to connect to NJ/NX-series Machine Automation Controllers and motion control G5-series Servomotors and Servo Drives to increase the control speed over everyday communications protocols from workpiece detection to starting axis motion. Conventional communications standard 4 ms Reduced to 1/8 0.5 ms EtherCAT Time from Trigger Input to Producing Measurement Results Trigger input Communications cycle as low as 500 µs Conventional communications standard Motion control that is synchronized with the communications cycle EtherCAT Features Measurement results Shortened by approx. 6 ms. Note:The times given above are typical times. They depend on parameter settings. Positioning Solution That Eliminates Workpiece Dwell Time: Continuous Alignment Patent Pending NJ/NX-series Machine Automation Controller For a Machine that requires micron precision, one alignment is not always enough to obtain an acceptable accep e tab ep ta a le error level, but executing multiple alignments ments greatly increases the processing time. OMRON provides eliminate des control methods that eli elimin m ate workpiece dwell time, the he main cause of increased incre ease ased d processpro proc o essing time.
