Compact Multi-Axis Motion Control for Designing Machines

Efficiently integrating multiple axes of motion within limited spatial and mechanical constraints remains a significant challenge for machine designers. Leveraging compact servo drives with real-time coordinated control systems addresses these constraints by delivering precise, synchronized and collision-free operation.

Jackson McKay, marketing engineer at Advanced Motion Controls, offered Machine Design a technical demonstration of the company’s FlexPro servo drives integrated with the company’s Click&Move automated control system, highlighting key advancements and compact multi-axis motion control.

The setup featured four coordinated axes, two rotational axes exhibiting bidirectional spinning motion, subsequently transitioning to linear sliding motion operating simultaneously without collision. This collision avoidance is achieved through sophisticated trajectory planning and real-time synchronization embedded with the Click&Move control algorithms, according to McKay.

From a system integration perspective, the FlexPro servo drives stand out for their power density and compact form factor. These drives are designed to deliver high current output and precise torque control while occupying minimal panel space and maintaining a reduced thermal footprint. These characteristics are necessary for machine designers working within constrained spatial envelopes or weight budgets, particularly in high-performance and dynamic automation applications.

The multi-axis coordination enabled by the platform facilitates synchronized trajectory execution and ensures access motion limits are respected to prevent mechanical interference. This level of control is necessary for systems that require complex kinematics or closely spaced actuators where collision risk traditionally limits achievable motion profiles. McKay says the compactness and modularity of the FlexPro drives promote scalable machine architectures, allowing engineers to implement dense actuator arrays without compromising accessibility or cooling requirements.
