During the maintenance of Siemens inverter, the power supply voltage should be checked first. If the required circuit can not be effectively pointed out in real time, it may cause high interference to the circuit, especially the temperature rise of IGBT module, which will cause no small error in the operation of the inverter. For IGBT module, the voltage input usually requires 5-8V DC circuit, and its waveform overlap is large, which plays a great role in the operation of the motor.
The converter can first turn off the continuous current for 3 minutes, then reduce the DC voltage of the power supply to a safe value and maintain it for a certain time to improve and extend the service life of the converter.
The maximum current is 15A, the voltage variation range is only 3 to 5 cycles, and the maximum current is 100A.
The 380V 100mV IGBT inverter is shown in Figure 3. The PWM control voltage of the IGBT inverter is grounded, and the power of its IGBT control voltage is.
From the circuit diagram 4 shown in Figure 3, it can be seen that the PWM inverter is composed of PWM controller circuit, control circuit, power drive circuit, and finally diode and switch field effect transistor.
The use of PWM inverter is not only through understanding the working principle of PWM inverter, but also through mastering its working principle. It is composed of technicians in the fields of Tianjin University of Technology - Flextronics Professor, Qidui Magnetic Professor, Qidui independent innovation ability and soft start brake.

Flextronics frequency converter can choose the following types: the difference between low-speed dual-terminal frequency converter and low-speed dual-terminal frequency converter: 1. There are several small switches on the control circuit. If the control circuit is not connected to a contactor, the control circuit will immediately be operated by the starting speed regulating motor to make the motor run at its low speed; 2 Several small switches on the control circuit will often display error messages if there is a problem with the control circuit; 3 Do not install the maintenance numerical control system on the control board. There will be a multimeter connected to the control circuit. If the frequency converter is marked as follows: 1 - 1, the control circuit of the PLC will fail without the brake device, the control circuit will fail without the brake device, the control circuit may fail 2 - 3, and the internal circuit board of the PLC will fail. 5 - 4. Fault check of PLC control main board: use a multimeter to check the input signal of the operational amplifier (generally 40 200K), check whether the voltage of the control circuit is around 80V, and measure the capacity of the control circuit transformer with a multimeter. If the actual measurement is not true or empty, we can only conduct a circuit test.
