Application fields
Thanks to its small footprint and its proven reliability in applications with high numbers of cycles, the H-811 is typically employed in photonics and in precision assembly. In such areas, it contributes to boosting the productivity of complex manufacturing processes and measuring procedures.
High dynamics combined with extreme reliability
The parallel-kinematic arrangement enables the hexapod to perform motion in 6 axes in an extremely compact design. Thanks to the use of brushless DC motors and its stiff mechanical design, the H-811 offers the dynamics required for active alignment applications, even if external interference (e.g., in the case of gluing processes) occurs. Extensive software tools provide support by simplifying the system tuning and making automatic routines available for alignment to an external analog control signal.
Motion simulation for protecting the overall system
The PIVirtualMove software, which can be downloaded free of charge, simulates the travel range, the alignment, and the permissible forces and torques of the H-811 to facilitate an optimum system configuration. In this context, both the chosen center of rotation and the center of gravity of the load are taken into consideration.
Work and tool coordinate systems and an emulation tool are included in the free software package belonging to the scope of delivery of the hexapod controller. The tools provided help to protect critical components such as optical or photonic parts.

When measuring position specifications, typical velocity is used. The data is included in the delivery of the product in the form of a measurement report and is stored at PI.
The maximum travel ranges of the individual coordinates (X, Y, Z, θX, θY, θZ) are interdependent. The data for each axis shows its maximum travel range when all other axes are in the zero position of the nominal travel range and the default coordinate system is in use, or rather when the pivot point is set to 0,0,0.
At PI, technical data is specified at 22 ±3 °C. Unless otherwise stated, the values are for unloaded conditions. Some properties are interdependent. The designation "typ." indicates a statistical average for a property; it does not indicate a guaranteed value for every product supplied. During the final inspection of a product, only selected properties are analyzed, not all. Please note that some product characteristics may deteriorate with increasing operating time.
