High speed, sub-micron positioning

High speed, sub-micron positioning Aerotech’s A3200 Digital Automation Platform is powerful, software only machine control system combining a high-performance, 32 axis motion engine with decentralised drives interfaced via Firewire with other machine control function modules such as HMI and soft PLC. This completely integrated solution includes a number of advanced software commands including Position Synchronised Output or PSO which allows the precise, on-the-fly synchronisation of the laser’s pulse, power level and firing pattern with the exact position of a multi-axis positioning system. PSO acquires the real-time position of all axes of motion on the A3200 using encoder feedback and processes a two or three axis vector path to provide a control output for laser firing which is exactly synchronised to the 2D or 3D contoured profile. For extremely high accuracy requirements, Aerotech’s HALAR (High Accuracy Linear And Rotary) option provides interferometer calibration and error mapping of an individual linear axis where micron level linear errors are analysed and the resulting calibration information is included as a look-up table in the A3200 motion platforms’ parameter file. A 2D HALAR option is also available where a two axis linear positioning system is analysed for error and calibrated in the same way. PSO can be combined with the HALAR option for the most ultimate precision available. The combination of PSO and HALAR is unique to Aerotech resulting in laser pulse synchronisation that achieves an unsurpassed level of accuracy.
