Q: When the inverter is running at full 50HZ, the output voltage decreases and the output current becomes smaller. What is the reason?: However, when the frequency is raised, the current will decrease if the load is not large, especially when the motor is idle. The magnitude of the current is determined by the load. If you can add some load, you will see the current rise. Speaking of principles, can be understood as the motor is a big inductance, when the power frequency increases, the motor impedance Z will become larger, the impedance is large, the voltage is constant, the flow of the current will naturally be small,

Q: What are the key points of frequency converter maintenance?: Selection of frequency converter and installation noticeType selection of frequency converter in general should pay attention to the matters (such as input supply voltage, frequency, output power, load characteristics and so on), also requires a good match with the corresponding motor requirements during normal operation, giving full play to the advantage of energy saving at the same time, to avoid the overload operation, and try to avoid dragging equipment such as pumps the inefficient work area, to ensure the efficient and reliable operation.The installation environment of inverter must try to be clean and dust, and has good ventilation environment, ventilation conditions can be considered the side wall at the bottom of the inlet exhaust, and the inverter is installed, the top and side shall be sufficient for the minimum cooling distance, inverter inverter heat dissipation, in addition, there are certain requirements the environmental humidity, high humidity, electrical insulation to reduce the inverter itself, bar metal parts easy to corrosion, and the humidity is too low and easy to cause insulation damage, generally keep the humidity between 40%-90%.

Q: The frequency converter is in use suddenly the speed reduces, then the debugging is out of control, how to do?: Excessive voltage generation and regenerative braking, the so-called inverter over-voltage, refers to a variety of reasons caused by inverter voltage exceeds the rated voltage, concentrated in the DC bus frequency converter DC voltage. In normal operation, the DC part voltage of converter is the average value after three-phase full wave rectification.

Q: What does the base frequency 60Hz represent in the inverter?: How to set the frequency converter: inverter frequency parameter should be set to the rated frequency of the motor is set up, and not according to the load characteristic set, even if the selection is not suitable for motor load characteristics or parameters must also try to follow the motor, easy over-current or overload.

Q: What are the possible causes of frequency hopping overload?: If the motor and inverter adapter, because the motor overload in inverter, this time is called the overload overload of the transducer, the current inverter rated current is compared; if the motor rated current is less than the rated current of inverter, the correct input motor nameplate and protection, the overload protection is often referred to as motor overload protection. Therefore, we must distinguish the specific circumstances of the current protection. Because of the overload point of the converter and the overcurrent point of the converter, the two protection alternates frequently.

Q: How to maintain the frequency converter will not damage, or regular maintenance?: The use of the environment on the frequency conversion is very large, the general installation environment requirements: minimum environmental temperature -5 degrees, the highest ambient temperature 40 degrees. The failure rate of the frequency converter rises with the increase of temperature, and the service life decreases with the increase of the temperature. The temperature of the environment rises by 10 degrees, and the service life of the inverter will be halved. In addition, the operation of the inverter is good, and the degree of environmental cleanliness also has a lot to do. Equipment failures can only be reduced through good maintenance work.When the frequency converter is broken, it is better not to give no maintenance experience to repair! Otherwise, it may get worse and worse

Q: There is much dust and moisture in my workshop. Many brands are not durable.: Inverter by internal IGBT drive voltage and frequency off to adjust the output power, the power supply voltage required to provide according to the actual needs of the motor, so as to achieve the purpose of speed, energy saving, in addition, there are a lot of protection drive, such as over-current, over-voltage, overload protection and so on. With the continuous improvement of the degree of industrial automation, inverter has also been widely used.

Q: What is the frequency converter AVR?: When the input voltage deviation from the rated value, the function can keep the output voltage constant, so under normal circumstances should be AVR action, especially when the input voltage is higher than the rated value, to protect the motor from excessive voltage caused by long-term insulation damage or high magnetic density caused by excessive heating core.

Q: What are the contents of frequency converter maintenance?: Operators must be familiar with the basic principles of inverter, functional features, with basic knowledge of electrical operations. Before checking and maintaining the frequency converter, the total power supply of the equipment must be cut off, and the inverter Chang lamp will be completely extinguished.

Q: What do you mean by the capacity of the inverter and the capacity of the motor?: That's not the case at all"Capacity" and "power" are essentially different. Usually we say that a large transformer capacity is how much KVA, but not to say how much KW, because the two are not the same thing
