Q: What's the use of switching frequency of converter?: The chopper device also has switching life, the higher the switching frequency, the shorter the life of the inverter, and will reduce the inverter output current and power. The smaller the chopping frequency, the higher harmonic content and the more serious harmonic pollution.

Q: How does the frequency converter change the voltage and change the speed of the motor?: The frequency converter regulates the speed of the motor, mainly by changing the frequency. The frequency determines the synchronous speed of the motor, and the speed of the motor can be lowered by reducing the frequency.

Q: How do you understand the ramp up (descent) time of the inverter? Thank you!: That is, the frequency converter starts from the time it takes to set the upper limit. It can be said to be the acceleration time, which can be set in the parameters of the converter. Then, the deceleration time is just the opposite.

Q: What's the role of an electric car, the part of a traditional car?: Vector converter (motor controller) in the electric vehicle is the DC power source into AC output, drive three-phase motor, and then the electrical energy into mechanical energy to drive the car running. It is the core part of the whole electric drive system, so its control performance is directly related to the reliable and efficient operation of the drive motor, which will affect the power performance of the entire vehicle and the comfort of the passengers.

Q: What are the possible causes of frequency hopping overload?: The meaning of inverter overload protection is that the output current of the inverter continues to exceed the rated current, but it has not exceeded the transient flow point, and the general duration is defined as 1min. The general overload constant torque converter is 150% 1min, variable torque converter is generally 110%120%/1min.

Q: I would like to ask, the inverter in use in the grid is very high?: Now the domestic and foreign status of power grid is different from that of Europe and the United States Department of conversion products to the domestic needs change, in fact, if you choose, you can choose domestic brands inverter, after all, or your own brand more familiar with the situation! Our factory in Chongqing, is used in conjunction with Kang high voltage frequency conversion, suitable for input voltage range comparison, but also very suitable for domestic power grid conditions.

Q: What is the over-current of the inverter?: External cause:?1, the motor load mutation caused by excessive impact, resulting in excessive flow.?2, the motor and motor cable phase or insulation damage to each other, resulting in short circuit turns to the ground, resulting in over-current.?3, over-current fault and motor leakage reactance, motor cable coupling reactance, so choose motor cable must be selected according to requirements.?4. Power factor correction capacitor or surge absorption device on the output side of inverter.?5. When the speed feedback signal is lost or abnormal, it will cause excessive flow, and check the encoder and its cable.

Q: I do mining equipment, recently I used ABB frequency converter to put into our equipment, but the problem of interference really gives me a headache! We have two pieces of equipment of SIEMENS S7-200 PLC, and is used in point to point protocol communication with each other, when the converter work PLC communication interference! There are monitoring equipment, converter work, there are a large number of snowflakes on the screen, simply do not see! Not even an internal phone! I've done well in grounding, but I still can't do it! Is there any master who can teach me a trick?: Solutions to interference caused by electromagnetic radiation:1. access reactor2., the correct grounding - grounding wire as close as possible to the frequency converter, the principle of power lines, frequency converter for the ground wire must be usedThe ground wire is separated from the other equipment, and the earthing of all the equipment must be avoided before grounding.The earthing terminal of the frequency converter can not be connected with the zero line.3. access filter.4. reduce carrier frequency.

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?: Constant power load:The torque required by machine spindles and rolling mills, paper machines, and plastic film production lines is generally inversely proportional to the rotational speed, which is called constant power load. The constant power nature of the load should be in terms of a range of speed variations. When the speed is very low, the mechanical strength limit, TL can not be infinitely increased, at low speed into a constant torque nature. The constant power area and the constant torque area of the load have a great influence on the choice of transmission scheme. When the motor is in constant flux speed regulation, the maximum allowable output torque is constant, which belongs to constant torque speed regulation. While in the speed regulation of magnetic flux weakening, the maximum allowable output torque is inversely proportional to the speed, which belongs to constant power speed regulation. If the constant torque of the motor and the range of constant power speed are consistent with the constant torque of the load and the range of constant power, the capacity of the motor and the capacity of the converter are all the smallest, which is called "matching".
