Q: How does the frequency converter fit the brake unit and the brake resistor?!: The kinetic energy of the motor shaft are much different. The load on the motor shaft, the kinetic energy is different, for example, motor used in cranes, in addition to the kinetic energy, potential energy and objects, should add up to the shaft of the motor, the energy will be consumed in the resistance.

Q: What are the key points of frequency converter maintenance?: (brief introduction of main circuit of frequency converter)The main circuit of the inverter is composed of four parts: input, rectification, filtering and inverting. The three-phase alternating current is converted into DC through rectification and filtering, and then is converted into three-phase alternating current with arbitrary frequency and voltage. Middle DC link capacitor, due to the large capacitance, DC voltage of the main circuit is relatively stable, the resistance is very small, with the characteristic of the voltage source, a voltage type inverter in the speed control system of asynchronous motor, because the motor is inductive, capacitive reactive power at the same time as a buffer storage component.

Q: What does the base frequency 60Hz represent in the inverter?: The schematic diagram of the basic frequency parameters of the converter is shown in figure.Below the fundamental frequency, the output voltage of the converter varies with the output frequency, and the V/F= constant is suitable for constant torque load characteristics.Above the fundamental frequency, the output voltage of the inverter maintains the same voltage rating of the power supply, which is suitable for constant power load characteristics.

Q: 1, the frequency converter to the motor cable should be shielded cable? 2, whether there are specifications?: Or, ask another question: "under what circumstances can the frequency converter go to the cable of the frequency conversion motor without using shielded cable?" Is there a "no need to use shielded cable" basis?

Q: How does the PLC process the inverter output signal?: Depends on analog or switch volume, if it is analog, you can use analog input module, if it is the amount of switching, with ordinary IO on it

Q: What are the differences between the two quadrant and the four quadrant of the inverter?: Simply put, the two quadrant ordinary inverter can only drag the motor forward or reverse. Work in one and three quadrants. The kinetic energy of the motor idle time can only be wasted. (of an electric motor)

Q: How can I control the frequency converter with a computer?: Variable frequency speed control has been applied in the industrial field as the main means of AC motor speed control is very extensive, it has a wide speed range, steady speed and high precision fast dynamic response for a wide range of technical performance and reliable operation, has gradually replaced the DC motor speed control system. There are three main control modes of inverter: 1. through inverter panel operation, that is through the operation panel to change the output frequency and other operating parameters; 2. in the frequency converter analog input 0 ~ 10V or 4 ~ 20mA signal, by changing the size of input analog control of inverter output frequency converter; 3. through communication port (for RS485 control). The first method is generally used for manual adjustment and parameter setting on the spot, and the latter two are mostly used for automatic adjustment and remote control.

Q: What role does input and output reactor play?: The output reactor for the effective transmission distance of extended frequency converter, the instantaneous pressure effectively suppress the IGBT module when switching inverter, reduce noise, reduce the eddy current loss, protection of power switching devices within the inverter.

Q: Can a power converter be used in a motor with small power? Will it burn the motor?: Can a power converter be used in a motor with low power, depending on your load and what type of converter is it?.If it is only a common fan, water pump or light load operation, then basically no request, you can use, as long as the relevant parameters can be set.

Q: What's the difference between universal inverter and fan pump converter?: Fan and pump load:In a variety of fans, pumps, oil pumps, with the rotation of the impeller, the air or liquid within a certain speed range of resistance is roughly proportional to the speed of the 2 side of the n. As the speed decreases, the torque decreases by 2 times the speed. The power required for this kind of load is proportional to the 3 power of the velocity. When the required air volume and flow rate are reduced, the frequency and speed of air flow can be regulated by the frequency converter, so the energy can be saved substantially. Because the power required at high speed increases with the speed, and is proportional to the speed of the three side, so the fan and pump load should not be used in the ultra power frequency operation
