Yifan CNC system control principle

1, the system hardware structure of the whole yifan, the composition of numerical control system is shown in figure 1, mainly including industrial PC, control panel, MCT8000 multi-axis motion control card and its interface board, power supply, servo amplifier, and motor, relay and some of the security and protection circuit. With industrial non-real-time tasks in computer process control and real-time task handled by MCT8000 movement control CARDS, and the servo amplifier and power supply, motor, relay as the actuator of the system. Figure 1 yifan, numerical control system hardware structure diagram 2, the principle of the movement control CARDS MCT8000 series intelligent motion controller including the main control board, interface board and control software, etc. , is a new generation of open architecture of high-performance programmable motion controller. Its CPU by Texas instruments TMS320C3140MHzDSP, can through the ISA or PCI bus standard or USB interface connected to the main control machine at a high speed. Between master machine and controller adopts two-way communication, high-speed FIFO can provide 2 ~ 8 axis high speed and high precision servo control, main control machine can choose any PC series microcomputer. Compared with the traditional motion controller products, MCT8000 series product has an open structure, high speed, high precision, the online control, multi-axis synchronous control, reconfigurable, high integration, high reliability and safety, etc. MCT8000 in design adopted the advanced technology of hardware and software refactoring, depending on the control object can be set up to online system and refactoring, or through the software upgrade hardware. Can according to the different requirements of customers, can be adjusted at best controller hardware modules, match with corresponding BIOS, the user can I/O port of MCT8000 operation directly. MCT8000 provides a set of motion control functions, including the BIOS function library ( Direct manipulation MCT8000 all the I/O) , basic motion function library ( 1 ~ 3 d interpolation and motion control function) And expand sports function library ( Robot kinematics model and intelligent PLC code translator, etc. ) And the controller (online Point-to-point security based on TCP/IP communications protocol) 。 Motion control board structure diagram as shown in figure 2.
