The PRO560LM is part of Aerotech’s second-generation PRO-LM stage series with many improvements and added features. Enhanced positioning specifications, improved stiffness, and competitive pricing make the PRO560LM stage the ideal choice for both medium and highper-formance production applications. The PRO560LM was designed to be used primarily as the lower axis of a PRO560LM/PRO280LM XY stack. The design is also ideal for applications that benefit from a larger support carriage, increased roll stiffness, and higher motor force.

Rugged Mechanical Construction

A long-life recirculating linear guide bearing system and a low-friction sealing solution make the PRO560LM an attractive solution for industrial applications such as laser machining. The basic external construction of the PRO560LM design provides protection from debris while the side-seals prevent dirt and particulates from entering the stage. The curved hard-cover design provides a natural shape that prevents excessive debris from collecting on the stage.

Precision Motion Performance

The PRO560LM series stages are optimized with high-precision, noncontact linear encoders that are protected from debris by the stage sealing system. Precision recirculating linear bearings along with machining and assembly craftsmanship enable excellent geometric performance specifications.

Incremental and absolute encoders are available as standard options and enable minimum incremental motion down to 5 nm and sub-micrometer repeatability. The optional HALAR factory calibration improves positioning accuracy down to ±1 μm.

Accurate Positioning with ThermoComp

Temperature changes and thermal effects are some of the largest error sources in precision machines. All PRO series stages are available with Aerotech’s ThermoComp feature, an embedded temperature compensation unit that guarantees accurate positioning in variable temperature environments. Using this feature protects your process from real-world conditions, even in extreme industrial settings.

Direct-Drive Linear Motor

Aerotech’s high-power U-channel linear motors drive the PRO560LM. The ironless forcer coil provides high force with zero cogging for super-smooth velocity and position control. This ironless design is ideal for applications requiring outstanding contour accuracy and smooth velocity profiling. As with all Aerotech linear motor stages, the linear motor has zero backlash, no windup, zero friction, and excellent dynamic responsiveness.

Design and Integration Flexibility

The PRO560LM is designed with many standard features and options that make the design incredibly flexible and allow it to be easily tailored to a specific application. The PRO560LM is available in eight different models with travels ranging from 300 mm to 1500 mm and speeds up to 2 m/s. Configurable cable management solutions are available for single and multi-axis systems as standard options.

The base mounting holes are accessible from the outside of the stage allowing for easy mounting. Standard mounting holes for both English and metric optical tables are present in all travels. The tabletop is available with both English and metric mounting patterns and can be ordered with brush attachments to clear any debris that may collect on the stage hard cover. Tabletops with hole patterns that allow the direct attachment of Aerotech’s ADRS, ACS-LP, ADRT, ACS, and AGR rotary stages are also available.

The PRO560LM series is also available with cleanroom preparation and vacuum versions.
