PI Introduces A-341 XY/XYZ Positioning Stage That Provides Dynamic Error Mapping

Press Release Summary:

The A-341 Hybrid Gantry XY/XYZ Positioning Stage is offered with a frictionless air bearing guiding system and a unique hybrid bearing design. The stage offers 300 x 300 to 500 x 1000 mm XY travel and 2 m/sec maximum velocity. The product is equipped with absolute measuring encoders and ironless linear motors that eliminate cogging. The device is suitable for step and scan applications. It comes with an optional vertical axis with either ball screw drive or linear motor and pneumatic counterbalance.


Original Press Release:

Hybrid Gantry Stage Provides Precision XY/XYZ Motion with Linear Motors, Air Bearings, and Ball Bearings

PI's new A-341 hybrid gantry XY/XYZ positioning stage provides the framework for controlled precise overhead motion that is often sought after for 3D printing, assembly, pick-and-place, alignment, inspection, and industrial automation applications. The A-341 HGS hybrid gantry is designed to combine maximum throughput with smooth and highly accurate motion in a compact envelope.

PI's novel gantry features a unique hybrid bearing design. The cross axis utilizes a frictionless air bearing guiding system, which allows for excellent velocity control, repeatability, straightness, and cleanliness. The lower dual-motor axis uses precision mechanical linear bearings for rigidity and reduced size. This combination of bearing technologies offers an overhead gantry motion platform optimized for step and scan applications in the smallest possible form factor. Absolute measuring encoders render homing procedures unnecessary and ironless linear motors eliminate cogging, providing smoother motion without vibration and better velocity control.

Optional Z-Axis

An optional vertical axis (Z-stage) with either ballscrew drive or linear motor and pneumatic counterbalance can be integrated with the gantry cross axis.

 

Features of the hybrid stages include:

  • 300x300 to 500x1000mm XY travel
  • Absolute encoders, 1nm resolution
  • Z-Stage options: linear motors or ball screws
  • Dynamic error mapping
  • 2m/sec max velocity (cross axis)
  • Cable carrier option, e-chain
  • Water cooling option for high acceleration / high duty cycle applications

Industry-Leading Motion Controllers

The HGS Gantry is coupled with industry-leading ACS controls and drives that offer superior servo performance, advanced control algorithms to improve dynamic performance and error compensation specifically for gantries, and a wide suite of software development tools.
