Optimizing precision and accuracy | Jul 2007
Remember the dartboard analogy? Darts landing near the bull's eye mean accuracy, whereas misfires landing close together, but far from the bull's eye, are more indicative of precision or repeatability. Today's motion systems, of course, usually demand both. Consider these tactics and tools for hitting the mark each and every time. Compact controller AMKASYN controllers contain a real-time-capable
Handling harsh environments | Sept 2007
If it's not one thing, it's another. Whether your designs are fighting off flying debris, holding their breath in a caustic chemical immersion, or surviving the rigors of extreme heat and humidity, it's your job to protect them. Following are some expert tips and tools to help your designs stand up to the harsh environments they're headed into. Enclosed cable carriers Energy Tubes prevent damage to

Making sense of position sensors | Sensor selection How does sensor selection contribute to productivity in today's motion-centric automation environment? | Oct 2008
Sensor selection How does sensor selection contribute to productivity in today's motion-centric automation environment? Michelle BEI: Selecting the correct environmental, mechanical, and electrical sensor specifications for your application will provide the longest life for your position sensor and will also help reduce system downtime. It's important not to over-specify or under-specify the sensor.

Out with the glass, in with the steel | Rotary and linear encoders are standard equipment in today's automated motion systems
Rotary and linear encoders are standard equipment in today's automated motion systems. Both types, generally, are optically based, relying on light passing through or reflecting off a scale and then interpreted by opto-electronics. For rotary sensing, this works well, but the same cannot be said of optical technology when it's used in linear motion applications. One lingering problem stems from the
Addressing encoder error | Jan 2007
Encoders are widely used to help control machine position and speed. Typical encoder output, a series of quadrature signals, consists of two full square waves, offset by 90 in phase. The number of quadrature cycles an encoder generates per revolution determines its resolution the smallest positional change it can measure. Particularly for position feedback, it's common practice to specify an encoder
