The highly dynamic AL8000 linear servo motors from Beckhoff now meet even higher requirements for accuracy and synchronisation with the new TwinCAT Cogging Compensation software (Engineering TE5920, Runtime TF5920). This makes the linear motors particularly suitable for high-precision applications such as milling or laser cutting machines. The cogging compensation software makes use of machine learning (ML) which is seamlessly integrated into TwinCAT and applied on a fully automated basis.
Cogging forces in linear motors are caused by the magnetic attraction between the iron core in the primary part and the permanent magnets in the secondary part. This physical effect leads to an unwanted and uneven ‘cogging’ of the motor, meaning that applications with extremely strict accuracy and synchronisation requirements can only be executed to a limited extent. This is where the AL8000 linear motors, in combination with the TwinCAT Cogging Compensation software, offer an optimal solution: the cogging forces are reliably compensated for with the help of this software, which takes not only magnetic effects into account, but also those of the mechanical design or energy chains. As a result, the range of possible applications for the AL8000 iron-core linear motors is significantly expanded.
Cogging compensation is based on the fully automated application of machine learning in TwinCAT. The software independently records the necessary cogging data in the respective customer application as part of a reference run over the entire length of the linear motor’s magnetic track. With the help of the data acquired in this way, the software trains a neural network which is ultimately integrated into the control system for current pre-control. By adapting the current pre-control in this way, the lag error can be reduced by up to a factor of 7 and the synchronisation of the machine increased by up to a factor of 5 without any hardware changes to the AL8000.
More movement on the market
Motion Control & Drives
If you want to move something, you have to be able to control the movement. When positioning in the nanometre range everything matters and requires high performance motion control. Six years ago, Aerotech therefore set itself the goal of revolutionising the market for precision motion and machine control systems.
