Kewei HM series motion control product introduction
 Introduction to the characteristics of HM series motion control products
    Among the requirements of many automatic lines, there are real-time control requirements for multiple parameters of time, speed, and trajectory (displacement). Traditionally, mechanical methods can be used to solve the fixed problem, such as the use of gears to achieve multi-axis synchronization, and the use of cams to achieve reciprocating positioning, which meets the needs of fixed processes at the expense of energy consumption and process automation costs. With the development of automation technology, people have abstracted objects that have real-time control requirements for time, speed, and displacement into various mathematical models, and implemented them in electronic devices, resulting in motion control products.
    Based on the IEC61131-3 environment, PLCopen has released standards for motion control products for development, installation and maintenance, and cross-platform motion control. Many internationally renowned companies are not only participants in standard formulation, but also product providers. Such as B&R, Rockwell/Siemens, etc.
   Standardization requires hardware independence to meet the high, medium and low demand of the market; products have the same appearance and characteristics externally, which is convenient for standardized installation and maintenance. It also requires the software to be independent, have a public development environment, improve acceptability, and be easy to use.
    Kewei Formula is a manufacturer of embedded PLCs and has a long and rich experience in the application and development of motion control products. The motion control products provided by our company follow the PLCopen Motion Control standard and combine the status quo of my country's machinery and equipment manufacturers to provide a low-cost solution. For motion control products encapsulated by function blocks, hardware and software are independent of each other, which improves the utilization efficiency of software function blocks and hardware interfaces.
   In the software structure, four functional blocks are provided. A control process can be composed of four functional blocks to 32 functional blocks. The functions can occur in parallel and coordinate control to complete complex control tasks. The function block is independent of the hardware, and is applied to different hardware ports by developers and users.
   Examples of specific application functions. Such as: electronic gear (fixed and dynamically adjustable), synchronous tracking (cursor tracking, encoder tracking), position comparison output (high-speed valve array related control, rapid connection between processes), electronic cam (position corresponding to different reduction ratios) , Linear/arc interpolation, 256-segment acceleration/deceleration rapid positioning.
