Motion Control System Retrofits Increase Machine Productivity and Cut Lifecycle Costs

Retrofitting the control system on an existing machine can provide a significant increase in performance. At the same time, it retains the investment in mechanical and power components that may still have many years of useful life. And for an OEM machine builder, upgrading the control system on an existing design can bring much of the benefit of developing a new machine at a fraction of the cost.

Non-Destructive Testing

Repetitive non-destructive testing (NDT) applications abound, and designers should consider using programmable motion controllers to power flexible testing scenarios. Fluid power should be considered where a predictable amount of force must be exerted, where the compressibility of the fluid medium can be used to avoid damage to the device under test, or where heavy loads must be held or moved as part of the testing process. Electric servos can also be used to power test axes if force can be controlled.

Hydraulic Motion Control in Forest Products Equipment

Precise control is key to getting the greatest productivity out of hydraulic systems. A common challenge is applying pressure control to logs or cants firmly without slipping or causing damage – especially under potentially powerful counteracting forces such as those provided by saws, blades or grinding wheels.

Using sophisticated electronic motion controllers, hydraulics continues to be the power of choice for many wood products machinery ap-plications.

Needs of Metals Industry Applications Drive Selection of Motion Controllers

The metals manufacturing industry is constantly evolving to require improved machine productivity and production of smaller batches of products. Machine designers and integrators are concerned with decreasing the impact of machine changeover times and the variability of operator skills and accuracy on the quality and throughput of manufacturing processes. The decisions they make can also have a major impact on decreasing lifecycle costs. Hydraulics can easily provide the power for even the heaviestduty applications, however traditional hydraulic control systems often lack the precision to produce highly accurate and repeatable mo-tion. For new machines and upgrades of older machines, one key to meeting cost and productivity goals is the use of a modular system design that incorporates a digital electronic motion controller.

Needs of Plastics Molding Machine Market Drive Selection of New Motion Controllers

The need for machine builders and owners to be competitive in the plastics industry is driving some key requirements on machine designers and system integrators. The first is the need for achieving higher productivity and higher quality output, while keeping manufacturing costs down. This is accomplished in part by making control systems “smarter,” capable of supporting smoother, more precise machine operation.
