Reference-class 6-axis positioning system
Parallel-kinematic design for six degrees of freedom, making it significantly more compact and stiff than serial-kinematic systems, higher dynamics, no moved cables: Higher reliability, reduced friction. suitable for vacuum environments to 10-6 hPa.
Brushless DC Motor (BLDC)
Brushless DC motors are particularly suitable for high rotational speeds. They can be controlled very accurately and ensure high precision. Because they dispense with sliding contacts, they run smoothly, are wear-free and therefore achieve a long lifetime.

The simulation software simulates the limits of the workspace and load capacity of a hexapod. Therefore, even before purchasing, you can check whether a particular hexapod model can handle the loads, forces, and torques occurring in an application. For this purpose, the simulation tool takes the position and motion of the hexapod as well as the pivot point and several reference coordinate systems into account.
Application fields
Industry and research, micromanufacturing, medical technology, tool inspection.

The cables fixed to the H-811.I2V are not drag chain compatible.
Note on outer diameter data transmission cable: The data transmission connection consists of 2 cables that end in one connector. The specified diameter applies for each cable.
Air-side connecting cables are not included in the scope of delivery and must be ordered separately.
For continuous operation in a vacuum, restrictions on operating parameters may be necessary due to heat generation.
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.
