Aerotech to demonstrate systems engineering capability
At Machine Building 2008, Aerotech (Stand 2000) will demonstrate its Probot automated multi-axis pick-and-place system that combines direct-drive and ball screw-driven linear stages, tightly synchronised by a distributed network of Ensemble panel-mounted intelligent drives and communicating with an Allen Bradley PLC using an Ethernet/IP network.
Showing Aerotech's engineered systems capability to the full, the complete seven-axis system includes a three-jaw gripper, the machine base with enclosure, and full cable management.
Aerotech's Ensemble CP/MP/CL multitasking, DSP-equipped, intelligent servo drives feature deterministic real-time Ethernet networking for up to ten axes - allowing tightly synchronised motion and machine control with microsecond-level interpolation. The multitasking controller architecture provides point-to-point motion, linear and circular interpolation, electronic gearing, and velocity profiling. A wide choice of programming languages includes Aerotech's own AeroBASIC, Microsoft .NET, C++, LabVIEW over Ethernet and many more.
The Ensemble CP/MP/CL range comprises 10, 20 and 30A peak current, panel-mount intelligent drives available in direct-on-line and separately powered versions. Drive technologies include 20kHz PWM amplifier stages for brushed or brushless servomotors and stepper motors or linear amplifiers for ultra-high precision/low-noise applications. Also available is the Ensemble Epaq range with the same amplifier and controller specifications but with rack-based options suitable for multi-axis configuration in 19inch desktop or cabinet-mounting alternatives.
Probot features Aerotech's new low-cost ATS115 and ATS165 range of medium-precision positioning stages with linear motion guide bearings, precision ball screws and durable hard cover/side-seal protection. These high-performance servo motor-driven stages have nominal widths of 115 or 165mm with a travel range from 50-600mm. Maximum speeds are up to 300mm/s and bidirectional repeatability is to +/-1.0um per-axis. The ATS range is suitable for Cartesian robot configuration, offering long and trouble-free use in medium-duty manufacturing and test applications.
Also featured on the demonstration are Aerotech's LMA series linear motor-driven, dual-carriage stages that offer micron-level positioning accuracy with speeds up to 5m/s, 5g acceleration performance and a travel range to 1.5m. These stages offer exceptionally long life and low maintenance for high-throughput, high-precision pick-and-place machines, automated test stations and assembly equipment.
Aerotech will also be exhibiting a selection of linear and rotary positioning mechanics, along with motion and machine controls, demonstrating its extensive capability as an engineered motion and mechatronics systems designer and manufacturer.
