The parallel-kinematic positioning system for six axes is highly convincing: The H-820 Hexapod from PI (Physik Instrumente) reaches all specifications after the endurance test.
The requirements of the test were challenging: A million cycles at a maximum load of 20 kg and maximum velocity of 20 mm/s. The H-820 proved to be unimpressed and reliably attained a linear repeatibility of 20 µm and a rotational repeatibility of 200 µrad, over the entire travel range of 100 mm in X and Y direction, 50 mm in the Z axis and rotational angles to 60°.
The H-820 system comprises a powerful digital motion controller. All target positions are conveniently given in Cartesian coordinates. For integration in automated processes, PI offers also a digital controller with EtherCAT fieldbus interface. Real-time Ethernet assures a fast and reliable connection to the overall system with short cycle times for precise synchronization.
Well-known for the high quality of its products, PI (Physik Instrumente) has been one of the leading players in the global market for precision positioning technology for many years. PI has been developing and manufacturing standard and OEM products with piezo or motor drives for 40 years now. With four sites in Germany and ten sales and service offices abroad, the PI Group is represented internationally.
