5464-836 Woodward speed control module

The 5464-836 is a microprocessor-based digital governor controller produced by Woodward, belonging to its classic 505 series.
It is primarily designed for speed control and protection of steam turbines. Below is a detailed introduction to this product:

I. Product Overview

  - Offers local/remote control priority selection to adapt to different operational scenarios.

Function of motion controller
1. Sports planning function

In fact, it is the benchmark quantity that forms the speed and position of motion. Appropriate reference quantities can

not only improve the accuracy of trajectories, but also reduce the requirements for rotating systems and mechanical transmission

components. Universal motion controllers typically provide motion planning methods based on limiting values such as impact, acceleration,

and velocity that can affect dynamic trajectory accuracy, and users can directly call the corresponding functions.

A trapezoidal velocity curve is generated through motion planning that limits acceleration; The motion planning that limits impact generates an

S-shaped velocity curve. Generally speaking, for CNC machine tools, using motion planning methods limited by acceleration and velocity reference

quantities has achieved excellent dynamic characteristics. For fast positioning systems with high acceleration and small stroke motion, there are

strict requirements for positioning time and overshoot, often requiring high-order derivative continuous motion planning methods.

2. Multi axis interpolation and continuous interpolation functions

The multi axis interpolation function provided by the universal motion controller has been widely used in the CNC machinery industry. In recent years,

the rapid development of the carving market, especially the mold carving machine market, has promoted the development of the continuous interpolation

function of motion controllers. There are a large number of short line segments in mold carving, and it is required that the fluctuation of processing speed

between segments be as small as possible, and the inflection point of speed change should be smoothly transitioned. This requires the motion controller to

have speed foresight and continuous interpolation functions. The continuous interpolation motion controller specially designed for small line segment processing

technology launched by Gu Gaoxin Company has been well applied in fields such as mold carving, laser carving, and flat cutting.
