New compact X-Y Cartesian gantry micro-positioning system
Aerotech is launching the new AGS1500 X-Y Cartesian gantry micro-positioning system, which is part of the company's ultra-high precision AGS series that features direct-drive brushless linear motors, non-contact optical encoder feedback, linear bearings, cable management and optional granite support bases and machine frames. The new small-footprint AGS1500 is available in four X-Y travel range options from 200mm to 500mm and retains the impressive dynamic performance and accuracy characteristics of Aerotech's longer travel AGS15000 model, with nanometre-level resolution, maximum velocity of 3m/s and acceleration to 5 'g'.
Aimed at high-throughput production and test micro-positioning applications, including precision micromachining, machine vision inspection, automated assembly and precision dispensing, the AGS1500 can be supplied with counterbalanced Z axes and rotary axes as complete customised motion sub-systems for turnkey operation, complete with customer-specified fixtures, cabled services and other special requests such as an electroless nickel finish for ESD protection.
The AGS1500 X-Y gantry includes dual brushless linear servomotors and non-contacting optical encoders for the base axis, and Aerotech's HALAR calibration option helps to ensure an overall stage accuracy of better than +/-1.5um and repeatability to +/-0.5um for the 500mm travel version.
Using Aerotech's encoder multiplier technology, resolution can be specified between 1um and 1nm, and X-Y orthogonality is within 5 arc-sec. The planar stage design includes a fully preloaded linear motion guide bearing system with wiper seals and grease fittings for long-life, low-maintenance operation for lower axis stage loads up to 37kg and payloads on the upper axis to 3.2kg.
Aerotech's cable management system (CMS) includes connectors at both payload and opposite ends of the energy chain, with large bend radii and high-flex cables used. Customers' electrical and pneumatics supplies can be routed through the CMS, thereby simplifying installation and system commissioning.
The AGS1500 is typically supplied complete with Aerotech's high-performance motion controls and servo amplifiers to ensure optimum performance. These include the A3200 Digital Automation Platform, the new MotionPAC, and the Ensemble and Soloist standalone motion controllers with integrated drives. Through the range a choice of PC-based software-only controls or standalone systems in rack- and desk-mounting options are available to suit customers' applications. All Aerotech controllers offer a wide choice of machine controls and sophisticated motion commands that can include IEC 61131-3, Microsoft .NET Framework and LabVIEW programming capability, with advanced software and analytical functions that are designed to optimise machine performance, increase precision and improve throughput.
