Application Illustration:SAJ 8000M series for Food Packaging Machine The speed of the food packaging machine is regulated by the potentiometer. The keyboard on the control cabinet can display the speed of the motor. The RPM =(120× F057 output frequency / F052motor poles)× gear ratio. The user doesn’t need to change the relative parameter as it is configured by the factory.The tracing system is the control core of the food packaging machine. It is controlled by the PLC program. The accurate position can be carried out according to the shape and size of the packaged things. Adopting two-way tracing technology, the accuracy can be increased. During the producing process, the error can be found out in time. The accurate rectification of the error can avoid the waste of packaging material.When operating, the film sign sensor will check the color code and at the same time, the micro switch is tracing the position of the machine. The above two signals will be transmitted to the PLC whose Y6 (positive trace) and Y12 (reversal trace) control the tracing system. If the check doesn’t conform to the demand after tracing for setting times, the machine needs to be stopped for further checking. The driver system of food packaging machine is simple with application function, but it requires high performance of dynamic driving. Also, it requires high stable accuracy and quick response. Thus, it’s very important to choose the high performance frequency inverter such as SAJ 8000M series with excellent technology index.

Advantages: With the vector control technology and the auto tune function, it can adjust the frequency automatically. It can stabilize the rotating speed of the motor when the load is changed. With high steady-speed precision and quick response, SAJ 8000M series can meet the requirement of high performance transmission control and reduce all possible damage brought by system failure. Also, its maintenance cost is lower. It can work without speed sensor. Multi-function, stable performance, small size, run with low noise Appendices:SIZE:(mm)
