Integrated automation and motion control simulation software provides simple and quick virtual commissioning for machine builders. By Kevin Wu and Colm Gavin | Siemens Digital Industries In the development of any new machine or plant, faults are almost inevitable. Failure during commissioning is especially problematic, because it’s likely to significantly increase costs and delay the […]

What is friction compensation in servo control?
Friction, which is the resistance to relative motion between two bodies, occurs in all sliding and rolling motions. In components that use lubrication to separate rolling or sliding surfaces — such as bearings and gears — there are typically two types of friction: static friction and dynamic friction. Static friction — also referred to as “stiction” […]
How to size an electric-motor-driven chain-and-sprocket system
In previous motion-sizing articles, we reviewed how to properly specify (using software) a ballscrew-driven motion axis. Then we reviewed how engineering teams can use a similar software-based approach for sizing rack-and-pinion-based servomotor-driven axes on the same five-axis gantry. Now we’ll explore the process for sizing the components (using that same software) for an electric-motor-powered axis […]
New module, software from Control Techniques boosts motion performance
Control Techniques, part of the Nidec group, has launched the next generation of its Motion Made Easy servo control suite. The new PTi210 module, and accompanying software, are designed for use with Control Techniques’ Unidrive M and Digitax HD servo drive platforms. Integrating PTi210 enables designers to access the comprehensive, easy-to-use PowerTools Studio software interface. […]
Breaking the old rules of inertia matching for servo applications
Modern servo drives with advanced tuning capabilities — when paired with performance servo motors having high-resolution feedback — can eliminate load-to-motor inertia-mismatch concerns. By the Kollmorgen engineering staff The accepted principle of matching motor to load inertia is no longer pertinent with today’s faster motion-control processors and advanced control algorithms. This outdated inertia-matching method of […]
What role does Linux play in motion control systems?
Operating systems manage the communication between hardware and software in devices such as servers, computers, mobile phones, and embedded systems. Most personal computers and laptops use either Microsoft’s Windows operating system or Apple’s macOS, and mobile devices such as phones and tablets primarily use Google’s Android operating system or Apple’s iOS. In the industrial world, […]
Part 3: Trends in Ethernet, PoE, IO-Link, HIPERFACE, and single-cable solutions
As we explored in Part 1 and Part 2 of this six-part series, machine designs are evolving with wireless connectivity, cloud-based operations, and open programming. In this installment, we explore how Ethernet has continued its expansion in industrial connectivity. We also detail increasingly useful cable types for IO-Link and HIPERFACE … as well as cross-network […]
Part 1: Connectivity and IoT in motion and general automation
In this six-part series, we explore how machine designs are evolving with wireless connectivity, Ethernet-based networking protocols, cloud-based operations, open programming, and various forms of edge computing. Links at the conclusion of each part follow in order, and here is a listing of all topics covered: Part 1 ⚙️ Connectivity and IoT in motion and […]
Bosch Rexroth now sells new products in new ctrlX AUTOMATION platform
With the new ctrlX AUTOMATION platform, Bosch Rexroth has eradicated the traditional boundaries between machine control systems, IT, and the Internet of Things. Centralized and decentralized automation topologies can now be created flexibly with the scalable platform. Thanks to a Linux real-time operating system, open standards, app programming technology, web-based engineering and a comprehensive IoT […]
Beckhoff helps develop the CoroVent ventilator
Researchers at the Czech Technical University in Prague have developed a prototype of the cost-effective CoroVent lung ventilator. The team — called the Nonconventional Ventilatory Team (NVT) — is led by Prof. Karel Roubík. Roubík is a member of the Faculty of Biomedical Engineering at the university. The CoroVent intended to help prevent the collapse of […]
