Types of Encoders within the MPL and 1326 Servo Motor Series

Have you ever wondered how forming and metal cutting machines provide precise motion for lathes, bending for metal fabrication and milling or how a robotic vehicle mainly used in military applications with bomb detection systems is controlled, or how antenna positioning systems control the precision in elevation and azimuth? Well, a servo motor is at…

Hardware Comparison: Allen Bradley Servo Motor Selection Guide

Today’s motion control systems require motors that do many different things, such as precise positioning or controlled torque. Servo motors allow for better control of these conditions by allowing a high rpm spin at low torque yet slowing down and increasing torque as states require.   With position sensors, encoders, and gearing, microcontrollers can sense the actual…

Hardware Comparison: MPL Servo Motor Selection Guide

Motion control sits at the heart of most manufacturing and warehousing applications.  With accurate motion control, system designers can create closed loop, efficient systems that optimize performance across a wide range of industries.  One common requirement for many systems is for low inertia servo motors. Depending on the final product or application, low inertia servo…

A Guide to High-Speed Counters (HSC) used in Programmable Logic Controllers (PLCs)

A high-speed counter (HSC) is a functional capability within particular PLCs. HSCs count the frequency of the pulse of processes from systems with elements such as high-speed encoders.
Counters in PLCs are an obscure but critical part of all PLCs. They can be a software-defined, virtual entity having low-frequency inputs to process. In high-speed input cases, a hardware input module must be designed to ensure the control process’s proper operation to ensure the outputs’ accuracy and timely delivery.

Hardware Comparison: Allen-Bradley vs Siemens PLCS

The Allen-Bradley Logix family of controllers is considered the most popular programmable logic controller family in the US.  It consists of numerous variants but for this comparison we will look at the ControlLogix, CompactLogix and MicroLogix PLCs. By comparison, Siemens is much more common in Europe where their extensive line of PLCs are used in…
