In comparison to stacked stages, HXP Hexapods offer an easy, elegant solution to complex, multi-axis motion in a compact construction. Its dedicated firmware simplifies the programming of complex motion through the use of two coordinate systems and automatically computes coordinate transformations for straightforward programming of motion.
Program up to two virtual pivot points without calculating coordinate system transformations or powering down the controller. The two virtual pivot points are origins of the two definable coordinates systems: Tool, which moves with the top plate, and Work, which is a stationary reference. This allows the user to conceptualize how the sample and tool are manipulated. For this 6-axis device, complex motion is simplified for easy user program development.
RightPathTM Trajectory Control is a firmware feature that enables scanning motion along a defined trajectory, line, arc or rotation, with minimal runout and at a constant, definable speed.
Newport Hexapod's top plate is driven by six, synchronized, high performance actuators with encoder feedback at the leadscrew nut to providing precise MIM, low backlash and fast speed.
Each Newport Hexapod model differentiates itself with its own unique joint system which improve position stability under load. When compared to other hexapods of similar size, Newport hexapods have more than five-times the rigidity and twice the load capacity provided by either the spherical or cardan joint design.
Hexapods are ingenious and effective solutions to complex motion applications that require high load capacity and accuracy in up to six independent axes. Parallel kinematic motion devices provide six degrees of freedom (X, Y, Z, pitch, roll, and yaw) in a compact solution to multi-axis positioning. As an alternative to stacking multiple stages, hexapods have no moving cables, are lower in overall cost, and offers error compensated motion.
1) Travel ranges are interdependent. The listed values are max. travels per axis when all other axes are in their centered positions.
2) Value with standard setting (value with hysteresis compensation)
3) Open/Closed loop values of HXP50-MECAV6
Hexapods require -ELEC controller that can be ordered below. The two addtional driver slots can be enabled to drive up to two SingleAxis motion devices.
