Advanced Motion Controls announces improved AxCent design platform

January 30, 2017 - The AxCent (Axes for Centralized control schemes) product platform brings improvements to the design architecture that utilize years of experience in the industry and the latest advancements in modern servo system design.

As technology continues its shift from analog to digital, there is still strong demand for analog designs.  The reason?  Analog drives provide some benefits:

  • Simplicity - It's easy to train people to set the correct switch and potentiometer settings.
  • Track Record - AMC has been building analog drives since their inception. They have continuously improved their designs to mirror the advances in component technology.
  • Performance - When tuned to maximum performance, analog current loops can often times achieve higher bandwidth and faster response than digital current loops.

How can analog outperform digital?  It all comes down to the components.  In a digital system, A/D conversions and processing time can add delays ranging from 20 to 100 microseconds.  This may not seem like a lot, but in the highest bandwidth systems delays of this magnitude create a sizeable phase lag.

The other driving factor is cost.  Large volumes and mature designs make prices attractive for everyone
