Easy drive M200 series frequency converter in the fruit bag machinery application

I. Introduction

With the rapid development of the national economy, people's demand for food is getting higher and higher, fruit as people's daily food, nature is no exception, people are now not only the pursuit of eating enough more important is to eat well clean and hygienic pollution-free, so that the fruit bagging technology came into being, bagging is the production of pollution-free fruit products is one of the effective supporting technical measures.Fruit bagging technology to improve the appearance of fruit quality, through the bag, can prevent fruit rust and cracked fruit occurs, so that fruit ripening after the fruit points, fruit embroidery becomes smaller, lighter in colour, the skin is tender and smooth; at the same time to reduce fruit pests and pesticide contamination, due to the protective effect of the fruit bag on the fruit, effectively reduce the fruit of pests and diseases, bagging pesticides, soot and fungi are not easy to get into; and then cost savings, access toIncrease production and income.Fruit bagging to reduce pests and diseases, reduce fruit drop due to disease, improve yield, reduce production costs and inputs, to achieve a significant increase in yield and income effect!

Second, the fruit bag machinery used inverter M200 advantages

1, V / F control mode (can achieve a tow more) A, advanced vector control algorithm, optimised SVPWM output, low output harmonics, motor temperature rise is small. B. Optimum energy-saving operation is achieved through motor parameter detection.

2、Open loop vector control (SVC) mode A. Adopting TI high-speed motor control special DSP processor, it can complete the complex vector calculation with high speed and accuracy, and realise the complete decoupling of the motor. B. Adopting advanced motor model algorithm, it can output 150﹪ rated torque at 0.5Hz, with 0.5﹪ accuracy of speed regulation and 1:100 speed range.

3、Simple PLC to complete up to 16 speed control;

4、Built-in PID can easily form a closed-loop control system, suitable for pressure, flow and other process control systems.

5, standard RS485 interface, support MODBUS communication protocol, and the upper computer such as touch screen, PLC and other network communication.

6, perfect protection measures can achieve over-voltage, under-voltage, input phase loss, output phase loss, overload, overheating, overcurrent, external terminal failure, communication failures, current detection errors, motor tuning faults and other nearly 20 kinds of fault protection, higher reliability.

Third, the application of the site situation

IV. Concluding remarks

Frequency conversion speed control technology in the application of fruit bagging machine, so that the control system is simple, stable control efficiency, easy maintenance of equipment, greatly improving the overall performance of mechanical equipment, while having an excellent cost-effective.
