Requirements here were challenging: a million cycles at a maximum load of 20kg and maximum velocity of 20mm/s. The H-820 reliably attained a linear repeatibility of 20µm and a rotational repeatibility of 200µrad, over the entire travel range of 100mm in X and Y direction, 50mm 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 ensures a fast and reliable connection to the overall system with short cycle times for precise synchronization.
