Automation platform simplifies machine,
motion
Combining all major machine and motion control functions into a single, software based automation platform running on a standard PC provides a seamless and a scalable system.
By combining all of the major machine and motion control functions into a single, software based solution that runs on a standard PC and by providing an open architecture for specialised 'bolt-on' modules, Aerotech's A3200 Automation Platform represents a breakthrough in machine control technology that encompasses both a seamless and a scalable automation system System Integrators and OEMs using hardware based automation solutions typically need to integrate a combination of PLC, HMI and motion control modules from different suppliers and combine them with motorised positioning tables or gantries, mechanical actuators and often pneumatic or hydraulic control systems

Aerotech has introduced a revised section in engineering reference, which covers Vacuum Preparation for motion control specific applications.
Aerotech motion systems described for automation
Motion systems for automatic laser working, medical and life sciences manufacturing systems are described in Aerotech's Automation Solutions brochure, also available in German.
More complex machines might also involve vision systems for automated parts inspection or position measurement and even the simplest machines would involve specialist modules for such diverse requirements as temperature or pressure sensing, high speed position sensors, tension control units and a whole host of other process monitoring functions.
Whilst this is the most common approach to automated machine control, the use of several different hardware and software systems can be difficult, time consuming and expensive to build, often resulting in numerous sources of error and limitations in overall system performance.
The A3200 Automation Platform offers a choice of programming options for 32 axes of decentralised motion interfaced via a high speed IEEE-1394 Firewire network with dedicated modules for HMI, PLC and Vision.

Sealed gantry handling system avoids dirt ingress
A sealed version of a linear motor driven, X-Y gantry system is particularly suited to applications such as high throughput laser machining and welding.
Open frame air bearing stage has long life
An open frame air bearing stage provides the specification for through-aperture step and scan positioning and uses preloaded air bearings, direct-drive linear motors and high resolution encoders.
Low profile rotary stage offers high speed
A low profile, high speed, compact rotary stage provides a solution for compact positioning spindle applications and operates at up to 15,000 deg/s.
The complete system has been designed to be adapted to the most demanding production and inspection applications and is supported by software development, diagnostic and commissioning tools which help to ensure a competitive proposition with a lower cost of ownership when compared to conventional hardware based automation solutions.
A typical application for the A3200 Automation Platform could involve integrating a vision module with the motion system and coordinating a cutting process such as laser machining, drilling or milling.
The system would provide all the necessary tools and features to identify the position of the material to be machined and to adjust the position and signal to the cutter all within one system.
The HMI module could be programmed to allow an operator total control in selecting product and machining requirements.
Furthermore, diagnostic and process information can be sent to a central control system via fieldbus and as the system is totally scalable, additional workstations can be added if required.
A real advantage of A3200 integration is the dramatic reduction in wiring and hardware components combined with the potential for much faster software development timescales and increased system reliability.
Depending on application requirements, the A3200 Automation Platform can operate in real-time (RTX) or under the Windows environment.
Motion, HMI, PLC and Vision modules may be programmed in a choice of languages including Aerotech's own AEROBasic, RS274 G-code, C, C++, VisualBasic, Delphi and LabviewTM.
For the creation of process-based user interfaces, a complementary software package provides preconfigured Active X components for Windows leading to a significant reduction in development time.
By using a common language to program all of the machine control functions, the close connection between the individual control modules helps to maximise data exchange flexibility and process structure whilst maintaining real-time capability.
The Firewire distributed control architecture is used to deliver motion updates for position and velocity to Aerotech's networked servo drives (NDrive.
Each NDrive independently processes position, velocity and current loop closure at 20kHz update rates avoiding the processing bottleneck associated with hardware-based single processor control systems.
Motion control for up to 32 tightly synchronised axes is fully deterministic with no system degradation as the number of axes increase.
Motion capability includes spatial path (real 3D) contouring, cubic splining and interpolated positioning as well as full master/slave and electronic gearbox functionality.
A wide range of PWM and linear servo drives are available in stand-alone or 6-axis rack mounted format with peak current ratings from 80V DC at 10A up to 320V DC at 100A.
Open loop stepper drives can also be added to the network.
Drives have integral I/O for over travel, datum or other decentralised switching requirements.
An optional 10/100 BaseT Ethernet interface may be used to add third party I/O and PLCs.
The main PLC module may also be programmed with the industry standard IEC-61131 interface or via ProfibusTM with Siemens Step7.
The image processing module can be integrated at real-time level via a DLL and includes a wide selection of processing tools for part identification and measurements using the Matrox Imagaing Library (MIL).
The advent of the A3200 Automation Platform means that for the first time, it is possible to use a single computer to solve complex automation tasks.
This unique automation concept is setting a new standard and making it easier to find solutions for high precision, high throughput automation in such diverse applications as advanced laser machining and welding, medical device and life sciences, semiconductor and flat panel production and test systems, optical lens manufacture, rapid prototyping, electronic inspection systems and many more.
Beyond the A3200 Automation Platform, Aerotech also designs and manufactures complete positioning system solutions including brushed and brushless servomotors, direct-drive linear and rotary servomotors; ballscrew and gear driven linear and rotary stages; high performance direct-drive linear and rotary stages; linear motor based cartesian gantry systems.
Typical systems are supplied complete with motor power and encoder cables and all performance and calibration related documents plus full interconnection drawings to help integrators with their own system documentation.
In addition, all motor parameter set-up data for system configuration is included making commissioning straightforward.
These features are standard for every Aerotech product and with full product training and comprehensive on-line technical support, the true cost of ownership is extremely competitive. Request a free brochure from Aerotech ...
