The winning combination for high-speed laser marking Seattle WA

The advent of robust, high-speed and accurate laser marking system for production lines that demand automation control and monitoring, high throughput and minimal laser maintenance, is made possible by digital state space servo control and "low order mode" high repetition rate pulsed fiber laser technologies. The significance of this type of laser technology is its ability to match up with a high-speed scanner to deliver high-quality markings.

The advent of robust, high-speed and accurate laser marking system for production lines that demand automation control and monitoring, high throughput and minimal laser maintenance, is made possible by digital state space servo control and "low order mode" high repetition rate pulsed fiber laser technologies. The significance of this type of laser technology is its ability to match up with a high-speed scanner to deliver high-quality markings.

A digital servo controller consists of high-speed digital signal processor (DSP) to perform all calculations necessary for digital control of servo motors in torque, velocity or position mode. The controller’s interface with control and feedback signals, such as motor currents and voltages, position encoder measurements is provided by high-resolution analog-to-digital conversion (ADC) integrated circuits. Tuning parameters that can be extracted from an auto-tuning process are stored digitally inside the hardware to eliminate manual potentiometer tuning and problems associated with analog circuit drift and aging.

Furthermore, high performance DSP technology also allows for the implementation of advanced motor control algorithms such as model based predictive control for high bandwidth performance. The predictive model is derived from the state space equation of motion of laser scanner motor with motor position as observable and other dynamic variables such as current and voltage simulated. The servo predicts ahead of time the movement of laser scanner and constructs motor voltage signals to ensure that the incoming signal can be followed within the constraints of the power-supply system. The drive that incorporates state space model can deliver substantial bandwidth enhancements over an analog servo.
