New actuators for precise hexapod movements
Aerotech is expanding its Automation1 platform with the Automation1-HXA4 and Automation1-iHXA4 hexapod models. These compact devices enable the complete integration of six-axis motion systems into existing control environments.
This makes hexapod applications easier to configure and the coordination of moves with other axes of motion using the same controller easy.
“With the new drives, hexapods can be controlled like any other axis in the Automation1 network,” emphasises Brian Fink, Product Manager at Aerotech. “This allows users to significantly reduce development time, cabling effort and integration costs without compromising control precision.”
The Automation1 motion control platform is Aerotech’s central control system. It combines software, controllers, drives, and the HyperWire fibre optic communication bus into a unified environment for high-precision motion and automation tasks.
Functional architecture
The HXA4 and iHXA4 drives are designed for the second generation of the Aerotech hexapod family, which includes the HEX150-125HL model. They combine precise position control with integrated safety and diagnostic functions. Position-synchronised outputs (PSO) allow measurement or trigger events to be precisely linked to feedback position. The Safe Torque Off (STO) function ensures safe operating conditions during service or setup procedures. Analogue and digital inputs and outputs are available for direct connection of sensors, cameras, or external actuators.
Compact design, reduced complexity
The HXA4 and iHXA4 drives have only two main cables per hexapod. This significantly reduces the amount of cabling required. The compact housing facilitates installation in existing control cabinets or directly on the machine. Combining the controller and drive in a single device not only reduces space requirements but also the susceptibility to errors. Users receive a scalable solution that integrates seamlessly into existing automation structures.
The hexapod drives are suitable for a wide range of precision applications. According to Aerotech product manager Brian Fink, typical areas of application include: optical alignment, adjustment, and bonding processes; manipulation and packaging of photonic components; wafer and lens inspection; test setups in aerospace engineering; characterisation of electro-optical systems; and sample positioning in synchrotron and beamline experiments.
“The combination of Automation1 software, HyperWire communication and the HXA4 and iHXA4 models creates a consistent, scalable control concept,” explains Brian Fink. “This allows hexapods to be integrated directly into automated processes. The coordination of complex movements becomes simpler, more reliable and more economically efficient.”
