This paper will examine the similarities and differences between the two main types of switching amplifiers (transconductance and voltage) by addressing three key areas: performance, safety, and efficiency. … [Read more...]
Forms of Closed Loop Stepper Control
This White Paper will explain the three methods that are used to close the feedback loop around stepper motors in a control system. … [Read more...]
EtherCAT or Ethernet for Motion Control
Ethernet based bus solutions have become the dominant method of communications in the motion and industrial control. Since EtherCAT and Ethernet use the same physical hardware and are often used in concert, it can be difficult to differentiate between the two. Control systems designers can however … [Read more...]
Introducing Galil’s New H-Bot Firmware
This article will discuss the advantages and disadvantages of using an H-Bot for systems that use planar movement as well as Galil's H-Bot firmware solution for the DMC-40x0. … [Read more...]
Intro to Motion Control Systems
A motion control system is a collection of components put together in such a way that creates movement to a specific position, velocity, or acceleration. A closed loop motion control system consists of a motor, amplifier, motion controller, and feedback sensor. … [Read more...]
Closed-Loop Stepper Motor Performance Gains
Modern motion controllers can include the ability to run stepper motors with encoder feedback, resulting in true closed-loop motion control. This mode of motor control is very similar to standard three-phase brushless servo motor control, where the three phases are offset 120 electrical degrees. … [Read more...]
