With the rapid development of the national economy, people’s requirements for food are getting higher and higher. As people’s daily food, fruits are naturally no exception. People are now not only pursuing enough food, but more importantly, eating well, clean, sanitary and pollution-free. As soon as the fruit bagging technology came into being, bagging is one of the effective supporting technical measures for the production of pollution-free fruit products. Fruit bagging technology improves the appearance and quality of the fruit. By bagging, it can prevent fruit rust and fruit cracking, making the fruit ripening effect, fruit embroidery smaller, lighter in color, and smooth and smooth; at the same time, it can reduce fruit pests and pesticide pollution. , Due to the protective effect of the fruit bag on the fruit, it can effectively reduce the pests and diseases of the fruit. After the bagging, pesticides, smoke, and other bacteria are not easy to enter; furthermore, it can save costs and increase production and income. After the fruit is bagged, it reduces pests and diseases, reduces fruit drop due to disease, increases output, reduces production cost input, and achieves a significant increase in output and income
2. Advantages of inverter M200 used in fruit bag machinery
1. V/F control mode (one drive multiple) A. Advanced vector control algorithm, optimized SVPWM output, low output harmonics and small motor temperature rise. B. Realize optimal energy-saving operation through motor parameter detection.
2. Open-loop vector control (SVC) mode A. Using TI high-speed motor control dedicated DSP processor, it can complete complex vector calculations at high speed and accurately, and achieve complete decoupling of the motor. B. Using advanced motor model algorithm, 0.5Hz can output 150% rated torque, stable speed accuracy 0.5%, speed regulation range 1:100.
3. Simple PLC completes up to 16 speed control;
4. Built-in PID can easily form a closed-loop control system, which is suitable for process control systems such as pressure and flow.
5. The standard RS485 interface supports MODBUS communication protocol, and can communicate with the host computer such as touch screen, PLC, etc.
6. Complete protection measures can protect nearly 20 kinds of faults such as overvoltage, undervoltage, input phase loss, output phase loss, overload, overheating, overcurrent, external terminal failure, communication failure, current detection error, motor tuning failure, etc. , Higher reliability.
3. Application site conditions
