The Successful Application Of Frequency Converter In Leather Machinery Slash Machine

< p > it is understood that < a href= "http://www.91se91.com/news/index_c.asp > > leather machinery < /a > the application of frequency converter in the actual work has become more and more common, because the frequency converter plays a very good auxiliary role in the equipment, for example, when the asynchronous motor is of poor characteristics, the activation torque is low and nonlinear, therefore, in the whole process of winding up, avoid the winding motor under the 2HZ as far as possible, so as to ensure that the winding motor has the lowest speed limit.

It can also speed up the operation of the equipment and so on.

< p >, how does the frequency converter work in leather machinery < a href= "http://www.91se91.com/news/" > stripe machine < /a > how to work and complete its function function? The following will be discussed in detail: < /p >

< p > the working principle of frequency converter in constant tension control of the system < /p >

< p > the essence of constant tension control in the process of retractable reel is to know the change of the roll diameter during the operation of the load, because the change causes the output torque of the motor to change along with the change of the coil diameter in order to maintain the operation of the load.

Because of its torque control, the inverter can also control the constant tension of winding.

An Bang Xin inverter provides three analog input ports.

The three way analog input can be defined as a variety of functions. Therefore, one can be selected as a torque and the other as a speed limit.

For the slicing machine, the calculation of the roll diameter is calculated by the tension controller.

That is to say, by setting the tension on the man-machine or text, and calculating the winding diameter through PLC, the torque output that needs the output of the motor can be calculated, and the output of analog output can be sent to the torque setting end of the bang bang inverter.

< p > 1, the parameter setting of an Bang Xin inverter < /p >

< p > (1) adjust all parameters of the drive to factory value.

< /p >

< p > (2) separate the motor shaft from the load.

< /p >

< p > (3) set the motor's rated voltage parameters 01-02 and the motor's rated frequency parameter to 01-01.

< /p >

< p > (4) set the parameter 05-00 to 1, then press KeypadRUN command.

< /p >

< p > (5) after execution, check whether some parameters are automatically filled in the measured data.

< p > 2, Ampang Xin < a href= "http://www.91se91.com" > frequency converter < /a > closed loop vector operation debugging < /p >

< p > the operation mode is set to the panel to start, and the frequency given mode is given by the panel.

The operation mode is V/F+PG, set the frequency to 10Hz, then run to observe whether the frequency converter will report PG alarm. If PG is reported, the 10-01 will be set to 1, then the power will be turned on again.

Press the run button again to ensure that the frequency converter does not alarm, and press the Mode button to switch the display frequency and observe whether the 10Hz is fluctuating, so as to ensure that the debugging is completed.
