Aerotech demonstrate real time Ethernet/IP synchronisation and engineered systems capability
Article Type: New products From: Industrial Robot: An International Journal, Volume 35, Issue 3.
Real-time Ethernet intelligent drive range offers tightly synchronised multi-axis motion and machine control.
Aerotech's “Probot” demonstrates its capability for engineered application solutions.
Aerotech Limited has demonstrated its “Probot” automated multi-axis pick and place system combining direct drive and ball screw driven linear stages, tightly synchronised by a distributed network of Ensemblee panel-mounted intelligent drives and communicating with an Allen Bradley PLC using an Ethernet/IP network (Figure 1).
Showing Aerotech's engineered systems capability to the full, the complete 7-axis system includes a 3- jaw gripper, the machine base with enclosure and full cable management.

Aerotech's Ensemblee 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 multi-tasking 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 AeroBASICe Microsoft.NET, C++ LabVIEWw 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-online 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 19in. desktop or cabinet mounting alternatives.
The 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 to 600mm. Maximum speeds are up to 300mm/s and bi- directional repeatability is to +/21.0mm per-axis. The ATS range is ideal for Cartesian robot configuration offering long and trouble-free use in medium duty manufacturing and test applications.
Also featured on the demo are Aerotech's LMA series linear motor driven, dual-carriage stages which 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.
