Q: Frequency converter, fault, contact action: Frequency converter is the application of frequency conversion technology and micro electronics technology, by changing the power supply frequency of the motor to control AC motor power control equipment. The frequency converter is mainly composed of rectifier (AC DC converter), filter, inverter (DC AC converter), brake unit, drive unit, detection unit, micro processing unit and so on. 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: Surface grinder can add frequency converter, what are the advantages and disadvantages?: Three frequency converter successfully used in NC machine toolsIn recent years, with the rapid development of the economy, the machine tool industry has also made rapid progress: it is reflected in the wide application of new technology and the obvious improvement of enterprise benefit. At present, the mainstream of consumption in machine tool industry is CNC machine tools. From the domestic and international market demand for CNC machine tools, after the NC machine tool market has the following characteristics: first, the economic CNC machine tools is the mainstream of the future products. Two, using new technology to reduce costs and improve product stability is the key to enterprise survival. Below we in the machine tool drive aspect uses the frequency control speed to say SAJ frequency changer in this profession application situation:

Q: What does 0L1 stand for?: Overload is excessive load, more than the equipment itself rated load, the phenomenon is that the current is too large, electrical equipment heating, long-term overload of the line will reduce the insulation level of the line, and even burned equipment or lines.

Q: What does the base frequency 60Hz represent in the inverter?: For example: if the rated frequency of the motor is 20HZ, the fundamental frequency should be set to 20HZ; if the rated frequency of the motor is 33.3HZ, the fundamental frequency should be set to 33.3HZ; if the rated frequency of the motor is 50HZ, the fundamental frequency should be set to 50HZ; if the rated frequency of the motor is 60HZ, the fundamental frequency should be set to 60HZ; if the rated the working frequency of the motor is 100HZ, the fundamental frequency should be set to 100HZ.

Q: Check the fault information is the power supply voltage instability, but other inverters are running well, what is the matter? Will there be any other parameters are not set correctly, thank you!: This example is obvious, due to undervoltage, to find the problem of power, the first to exclude external problems, from the inverter inside to find the reasons.

Q: What is the upper and lower limit of the environmental temperature to ensure the normal operation of the inverter?: Inverter environment temperature(1) working temperature. The use of frequency converter should pay attention to the environmental matters, the internal is high-power electronic components, is easily affected by the operating temperature, the product is generally required to be 0~55 degrees, but in order to ensure safe and reliable work, when usedShould be considered under the best control in 40 DEG C. In the control box, the inverter shall be installed on the upper part of the box, and strictly comply with the installation requirements of the product manual, absolutely not allowed to sendA heat element or a heat generating element is mounted close to the bottom of the inverter.

Q: Why does harmonic generator produce harmonic? What's his working principle?: The harmonic generation mechanism of frequency converter is because of the non-linearity of frequency converter, including two parts: rectifier and inverter. For a simple example, the streams we see are, if there is no wind, and the bottom is flat, then there will be no waves, no ripples. This is because the water flows through the region is linear. Because of the fact that the wind and the water are not flat enough, these nonlinear conditions lead to waves and ripples.

Q: Does the number of inverter settings differ from the number of motor poles, and does it affect the use?: 1. motor speed control will not be accurate2. the working current of the motor may become larger, and the motor will be burnt out3., excitation what will change, but also may cause the motor heating, burnout, will also reduce the efficiency of the motor;4. may also burn the inverter.5. motor output may be affected.

Q: The frequency converter works with sharp noises. What's the process of converting electrical energy into mechanical energy?. The mechanism of sound making. Thank you: There is a sharp sound can only prove that you have problems with frequency conversion, frequency conversion stable operation can only hear the sound of the fan slightly. Although we are engaged in frequency conversion, but let me tell you this mechanism, really can not say, you can use frequency conversion, and play to his limit, have been very difficult.

Q: What is the main harmonic produced by a transducer? How about the degree?: The main hazards are:(1) the possibility of resonance in the power grid is increased, thereby causing high overvoltages or overvoltages to cause the risk of accidents.(2) increasing additional losses, efficiency of transmission and electrical equipment, and utilization of equipment.(3) make the electrical equipment (rotating motor, capacitor, transformer, etc.) run abnormally, accelerate the insulation aging, and shorten their service life.
