Variable Frequency Drives (VFDs) are a crucial component in industrial automation, providing precise control over a motor’s speed and torque. Numerous built-in protections and fault indications are provided with modern VFDs, including the commonly seen DC Bus Overvoltage Fault. This fault has several possible causes and this whitepaper explores each one, offering solutions to ensure…
Transformers of various types are needed for most automated machinery, so it is important to understand the selection and sizing basics. Power transformers play a key role in any electrical distribution system, and also for end-use equipment like industrial control panels. Although many engineers, designers, and installers encounter transformers during the course of their professional…
Stepper motors play an important role for motion control applications requiring more precision than standard variable speed motors, but not warranting the expense and complexity of servo motors. For many applications, a stepper motor solution occupies the sweet spot of providing the required performance, but at a much lower cost than servo solutions. This white…
There are three router-based methods for establishing remote access to industrial systems via a PC or mobile device—with each providing a different level of security, required implementation effort and integrated features. In today’s Internet of Things (IoT) world, remote mobile access is a necessity for many industrial applications. There are several ways of implementing this…
Today’s machines/systems are more connected than ever before with many utilizing cloud networks for remote access. Cloud networks come with inherent security risks and the StrideLinx platform goes above and beyond to ensure data security. This whitepaper outlines StrideLinx’s approach to security for the StrideLinx Cloud platform and the associated router. StrideLinx’s security strategy is…
Protecting operators from the safety hazards introduced by automated machines and robotic equipment demands an understanding of both the appropriate safety guarding level and the machine safety components needed to get the job done. As always, the designer must identify the safety risks, plan the best ways of addressing them, and ensure the proper application…
There are many important items to consider when choosing a controller for machine and process automation. Breaking down the equipment’s operational needs is a starting point and will help evaluate the range of controllers specified by OEMs or machine builders. Depending on how the equipment fits into the larger manufacturing environment, the automation system can…
Pneumatics have been used in automated machines for well over 100 years, with pneumatic technology developing and evolving for over a thousand years in some form or another, for example as boat sails. There have been many innovations over the years, and the basic pneumatic components such as valves, solenoids, cylinders, hoses and fittings are…
The line between programmable relays and micro PLCs has moved to a much lower price point over the last few years, making a micro PLC a better option for controlling many small to medium size machines. Micro PLCs are no more expensive nor difficult to use than programmable relays in these applications, and the required…
This white paper is a general guide to the specification, design and installation of automated control systems. The information and references are presented in a logical order that will take you from the skills required to recognize an operation or process suited for automating, to tips on setting up a program, to maintaining the control…
