CNC cutting machine power supply response speed analysis
Speaking of CNC plasma cutting machines, many people first consider the problem may be the power supply, then in the choice of power supply is not taking into account the power of the response speed, because this directly affects the smoothness of the surface of the cut product, Cutting speed, efficiency and a series of problems.

With the advent of all-digital AC servo systems, AC servo motors are also increasingly used in digital control systems. In order to adapt to the development trend of digital control, most of the motion control systems use stepper motors or all-digital AC servo motors as the execution motors.
Both servo and AC motors are similar in control mode (pulse train and direction signal), but there is a big difference in performance and application. Now compare the performance of the two.
Speed ​​response performance Different stepper motors require 200 to 400 milliseconds to accelerate from standstill to operating speed (typically several hundred revolutions per minute). Acceleration performance of the AC servo system is better. Take the Panasonic MSMA 400W AC servo motor as an example. Acceleration from standstill to its rated speed of 3000 RPM takes only a few milliseconds. It can be used in control applications requiring fast start-stop.
