When it comes to explaining the synchronizing capabilities of motion control, there may be no better example than today's modern printing presses. Such machines may include as many as 100 axes, all controlled by servo motors, stepper motors, and "hybrid architectures of daisy-chained controllers or PLCs." Motion Control online explains how "electronic line shafting" gives operators the ability to move various print modules on and offline while maintaining web tension, color registration, roller speed, and multiple other variables. All reasons why the process of printing, despite the Internet, is "alive and well" today.
