Motion control can be used in applications that can not previously bear the cost. However the servo hardware, such as drive, motor, and interconnects cables, is only part of the motion solutions. Engineers need to control functionality of a programmable control in many applications. Using a programmable control system is one of the most effective approaches to providing a complete cost-effective motion control solution that has motion capabilities.
Motion control systems can be broken down into two broad categories:
• Simple, motion of non-interpolated refers to a single axis or dual axes control. It is used for positioning – to move the object from point A to point B. For examples of simple motion include pick-and-place systems and conveyor control. A model of simple motion may have multiple axes, and each axis is controlled by independently of the other axes.
• Interpolated motion is a complex and coordinated motion. The interpolated motion has multiple axes that are constantly being positioned with regard to each other. It is used in machining processes and complex 3D positioning applications.
Selecting a control device that includes Pulse Train Output (PTO) functionality is one of the easiest and least expensive methods of implementing non-interpolated motion control. PTO functionality is the ability of a controller to accurately generate a specific number of pulses at specified frequency.
