Integrated motion/control offer advantages

Motion and machine control systems offer advantages for automated packaging and processing machine applications, providing fully integrated, single sourced systems.
Within the packaging and processing industry, many manufacturers use motion controls, PLC, HMI, and vision systems from different vendors; Aerotech specialise in providing such integrated solutions from a single source with an extensive range of feature-rich motion and machine controls, high performance servo and stepper drives and brushless linear and rotary servomotors with the advantage of lower system and integration costs, faster time to market and lower life-cycle costs. Aerotech's A3200 Automation Platform is a software only, 32-axis distributed motion control system that runs on standard Windows based PCs and combines tightly synchronised motion with a selection of 'soft' machine control modules for HMI, vision and PLC. Using the non-proprietary IEEE-1394 Firewire protocol, the controller provides a fully deterministic, high-speed, distributed control architecture in combination with Aerotech's Ndrive servo amplifiers which independently process position and velocity motion updates at 20kHz servo loop closure rates, with power ratings up to 100A peak current.

Multi-axis packaging machine operations such as fast registration or 'virtual line-shaft' based synchronisation are easily undertaken with all motion commands accessed in C, C++, Visual Basic or in AeroBASIC - a rapid prototyping development language based on RS-274 G-code.

Alternatively, the optional Ncontrol SDK software development kit may be used to program the unit with Windows based ActiveX components, C++, VB and .NET class libraries that help to reduce programming time and effort.

Machine control modules are available for HMI (Nview) and PLC (Nlogic) with the industry standard IEC61131 language.

A vision control module (Nvision VCM) supporting standard and non-standard cameras greatly simplifies quality control or part identification requirements.

As well as the integrated 10 base T Ethernet port on Aerotech's Ndrives, a devicenet compatible module is available for interfacing third party analogue and digital I/O or other machine control components.
