Q:How does MM430 frequency converter always report F003 fault?
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:Can 220V use frequency converter to drive three-phase motor with 380V?
The use of motor, if the star is connected to the corner of the connection can be, and if it is angle, then there is no way, and then the power of the motor will be reduced by about 4/10.
Q:Where is the frequency converter used?
The machinery manufacturing industry, including: elevator, automobile, textile, printing and packaging, paper making, hoisting machinery, food, tobacco, etc. the use of these pumps, inverter industry is mainly in electrical equipment, control and obtain the best product performance and output rate is the main purpose of energy saving is different from the 1 in
Q:What are the differences between electronic governor and frequency converter in motor speed regulation?
Is the original power inverter direct input three-phase asynchronous motor inverter in inverter internal access first, through PWM electronic converter technology will AC rectifier, inverter, a controllable frequency alternating current at the input to the motor, the motor operation can be controlled by V/F, output torque control and vector control control frequency, change the loop current, realize energy-saving operation, especially the energy saving effect is obvious in the motor at light load is a kind of energy-saving products, has been widely spread and applied.
Q:How does frequency converter realize variable frequency speed regulation?
V=60f/nvMotor speed fFrequency nMotor poles without frequency converter to change the motor speed, only by changing the pole of the motor to achieve, frequency is 50HZ; through the inverter to change the motor speed is running frequency, no need to replace the motor can realize the speed control. The principle of speed regulation is the formula above.
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: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".
Q:At the base block Yaskawa inverter is what reason?
This is the base block command, when the external input block command signal, the frequency converter will appear this code, the emergence of this code, the motor will rotate freely, does not affect the use.
Q:What role does input and output reactor play?
The input reactor is mainly used to restrain the interference of the higher harmonic produced by the converter to the power supply and other equipments. The output reactor is mainly used to restrain the damage of the higher harmonic caused by the converter.
Q:Application of ABB frequency converter
What are the differences between PWM and PAM?PWM is English Pulse Width Modulation (pulse width modulation), according to the law must change the pulse of the pulse width in a tone adjustment output and waveform.PAM is the abbreviation of Pulse Amplitude Modulation (pulse amplitude modulation) in English. It is a modulation way to change the pulse amplitude of pulse column according to a certain rule to regulate the output value and waveform.
