August 10, 2017 - Aerotech’s new product, ThermoComp, is designed to be a complete mechatronic solution to thermal errors. Through the employment of integrated hardware and sensors, and a proprietary compensation algorithm implemented via Aerotech’s A3200 controller software, ThermoComp works to minimize stage inaccuracy due to thermal effects even over extreme temperature ranges.
Additionally, internal self-heating is another major source of thermal-related positioning errors, particularly in stages without direct feedback devices such as ball-screw-driven stages. ThermoComp is intended to prevent environmental changes from affecting positioning performance, and also to diminish the errors caused through internal heating, eliminating up to 90% of the thermal-related errors caused by the self-heating of a ball-screw-driven stage. ThermoComp is currently available on all Aerotech PRO Series stages and operates through an integrated command set within the Aerotech A3200 controller software.
