The ED3800 easy to drive the inverter EASYDRIVE 
 EASYDRIVEED3800 series of high-performance current vector inverter series features: 
 A. Powerful control platform 
 ED3800 series inverter control core 32-bit RISC microcontroller, the computational speed of 1.3DMIPS, efficient completion of complex motor control algorithms can achieve true real-time control. The wealth of hardware peripherals greatly improve system integration and reliability. 
 Two. Leading control algorithm 
 The motor core control layer, the the ED3800 innovative vector control and the VF control technology perfect combination, the introduction of flux control theory, even in the VF control mode can achieve good motor control, while not sensitive to changes in motor parameters, greatly improves the robustness of the system control. 
 Vector control, using the classical vector control technology based on rotor magnetic field orientation principle, based on the principle of Flux Observer to decouple the rotor flux direction of the motor flux current and torque current, and control, respectively. Speed ??adaptive observer (MARS) to estimate the rotor speed the whole. Classic three-loop control structure, the position loop, speed loop and current loop control structure, in order to achieve a full range of location, speed and torque control. 
 3. Open hardware architecture 
 ED3800 series inverter provides a SPI interface with powerful scalability, open standard MODBUS protocol, customers can on this basis in the form of expansion cards for any industry-specific functions, without having to change the host hardware or software design, very large to facilitate the secondary development of the customer. 
 4. Communications and networking 
 ED3800 series inverter with MODBUS communication protocol of the international standards, such as convenience and PLC form a complete network control, and follow-up will be introduced to support a variety of bus protocol expansion card to meet the needs of an increasingly powerful communication network. 
 ED3800 series inverter for equipment manufacturers and end customers to provide highly integrated integration solution that can dramatically reduce the system of procurement and operating costs. To maximize profits and value for our customers to create. 
 The ED3800 technical parameters: 
 1, independent of outside lead keyboard, the keyboard of the machine and double Waiyin keyboard control and inverter operation status monitoring. The LED Waiyin keyboard, Simple keyboard, you can achieve all the features of the native keyboard. 
 2, Serial Communication: RS485 physical communication interface, embedded MODBUS protocol. 
 3, the terminal control functions for the user to select. 
 4, using high-speed DSP as the core unit to complete the complex current vector decoupling operator, the original vector control mode, adaptive motor environmental changes caused by changes in the parameters, which greatly improve the robustness (robustness) of system control. 
 5,4 v / f control mode, the vector control and V / F control, the perfect combination in one. 
 6, the rich combination of the frequency of instruction, best meet the needs of users of all kinds. 
 7, smart power-saving features, customers can monitor real-time output power and accumulated power consumption. 
 8, intelligent motor speed tracking technology to respond to grid flashover. 
 9, the torque control function can be achieved line speed synchronization control and tension control. 
 10, the pull-up current and sink current standard two multi-function switch input and output terminals, the switch signal is compatible with any external device on the market. High-speed pulse input and output functions 
 11, the counter, put frequency, the program is running, the PID function is designed as a standard feature. 
 12, a comprehensive early warning, monitoring, and protection functions. 
 13, good results of the multi-carrier control and carrier automatic adjustment function of the motor in the low frequency torque compensation. 
 14, superior cross-modulation function can improve the voltage output capability, thereby increasing the output torque at high frequencies. 
 15, the use of international standards MOUDBUS communication protocols to facilitate the formation of the network control. Follow-up communications card, launched to support a variety of bus protocols to meet the needs of all levels of customers. 
 16,4 encode the LCD keypad, keyboard operation is more direct and richer display. Users can out of the manual related operations. 
 17 high-power models can be equipped with 5.7-inch touch-control screen, the function menu and Help menu, new user interface, as the operation of their phones, allows the operator to off now. 
 18, a full range of independent duct, which greatly improve the reliability of the inverter in the long-running different applications such as textile, printing and dyeing, chemical fiber, paper, drawing, cement manufacturing industry. 

 ED3800 series products are widely used in lifting, paper, building materials, textile, CNC machine tools, petrochemicals, engraving machines, printing and dyeing, stone processing, packaging, printing, ceramics, drawing, pharmaceutical, and other areas, especially for low-frequency torque demanded high equipment.
