CHATSWORTH, CA — Delta Tau’s new laser galvanometer interface for its Power PMAC motion controllers simplifies and improves controls for laser scanning applications – including laser marking, PCB processing, micromachining, and medical device manufacturing.
The interface is based on the laser industry’s XY2-100 communication standard. It allows a single motion controller running a unified program to take over every aspect of a laser scanning process.
The interface’s single-controller architecture makes for easier programming. Rather than writing, troubleshooting and maintaining several distinct chunks of controller code, the Power PMAC with XY2-100 interface needs just one program for all the positioning tasks. That same program also controls laser power on-the-fly through PMAC’s PWM outputs.
The combined control system executes a single motion program that positions the galvo mirrors in the laser scanner and the x-y position of a scanner or work piece. Delta Tau’s spectral decomposition algorithms coordinate the galvo actuator’s high-frequency movements and the x-y positioning actuators. Speed improvements from this control system can be significant in applications that require frequent positioning of the laser scanning head in relation to the work piece.
