1. Exercise planning function
In essence, these are the reference quantities that determine the velocity and position of the motion. Appropriate reference quantities not only improve the accuracy of the trajectory but also reduce the requirements on the rotational system and mechanical transmission components. General-purpose motion controllers typically provide motion planning methods based on constraints on quantities such as impact, acceleration, and velocity that can affect the accuracy of the dynamic trajectory; users can directly call the corresponding functions.
Motion planning that limits acceleration produces a trapezoidal velocity curve; motion planning that limits impact produces an S-shaped velocity curve. Generally speaking, for CNC machine tools, motion planning methods that limit acceleration and velocity reference quantities already achieve excellent dynamic characteristics. For rapid positioning systems with high acceleration and short stroke motion, there are strict requirements for positioning time and overshoot, often requiring motion planning methods with continuous high-order derivatives.
2. Multi-axis interpolation and continuous interpolation functions
Multi-axis interpolation functionality provided by general-purpose motion controllers is widely used in the CNC machining industry. In recent years, the rapid development of the engraving market, especially the mold engraving machine market, has driven the development of continuous interpolation functionality in motion controllers. Mold engraving involves the machining of numerous short line segments, requiring minimal fluctuations in machining speed between segments and smooth transitions at speed change points. This necessitates motion controllers with speed look-ahead and continuous interpolation capabilities. Googol Technology has launched a continuous interpolation motion controller specifically designed for short line segment machining processes. This controller has achieved excellent applications in mold engraving, laser engraving, and planar cutting.
3. Electronic gear and electronic cam functions
Electronic gears and electronic cams can greatly simplify mechanical design and achieve many functions that are difficult to achieve with mechanical gears and cams. Electronic gears can synchronize the movement of multiple motion axes according to a set gear ratio, which makes motion controllers well-suited for applications such as fixed-length shearing and shaftless multi-color printing.
Furthermore, the electronic gear function can enable a motion axis to follow a function at a set gear ratio, whereby the function is determined by the motion of several other motion axes; an axis can also follow the combined speed of two other axes at a set ratio. The electronic cam function allows for programming changes to the cam shape, eliminating the need for regrinding mechanical cams and greatly simplifying the machining process. This functionality makes motion controllers well-suited for applications in areas such as the hardening of mechanical cams, cutting of irregularly shaped glass, and the production of fully motor-driven springs.
4. Comparison output function
This refers to a motion controller outputting one or more switching signals when the position reaches a set coordinate point during movement, without affecting the movement process itself. For example, in AOI (Automated Optical Inspection) flight detection, the motion controller's comparison output function enables the system to activate CCD rapid imaging when it reaches the set position, without affecting the movement. This significantly improves efficiency and image quality. Furthermore, this function of Googol Technology's universal motion controllers has also been well-appointed in laser engraving applications.
5. Probe signal latching function
It can latch the timing of probe signal generation and the position of each motion axis. Its accuracy depends only on the hardware circuitry and is unaffected by software or system inertia, making it well-suited for applications in the CCM measurement industry. Furthermore, an increasing number of OEMs are looking to integrate their extensive industry experience into motion control systems, customizing motion controller functionality for different applications and controlled objects. Googol Technology has developed a universal motion controller application development platform, enabling general-purpose motion controllers to possess a truly object-oriented open control structure and system reconfiguration capabilities. Users can load their own designed control algorithms into the motion controller's memory and reconstruct a special-purpose motion controller without altering the overall control system design.
