Control According to Webster: Defining a Motion Axis

Before tuning a motion axis, you must define the axis. If the control system doesn’t understand the axis properties or specifications, it can’t be expected to effectively complete the tuning process. When I need a definition for a word, I look at a dictionary. Or rather, back in 2002, I would have looked through a … Read more

Using PID and Feedback Loops for Precise Motion Systems

PID controllers are an excellent method of using feedback to turn an otherwise open-loop system into one which can follow a carefully prescribed profile, correcting for inconsistencies caused by the equipment, the environment, and even the products in the manufacturing process. In many systems, it is sufficient to send voltage to a motor or valve, … Read more
