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:How do you understand the ramp up (descent) time of the inverter? Thank you!
The reverse is the drop time, or the 0 speed. Water pumps and fan motors are basically not required to change. If it is an emergency stop, it is usually 3 seconds (depending on the frequency converter and process requirements).
Q:When the inverter is running at full 50HZ, the output voltage decreases and the output current becomes smaller. What is the reason?
I don't know if you're a manufacturer of car gearboxes, and we've also done car engine tests. The operation in the 50HZ when the inverter is not reduced voltage, if only a little decrease will decrease, this is due to increasing frequency, controllable silicon resistance increases, the corresponding motor voltage decreased slightly, not what the essence of influence.
Q:Hello everyone, I was doing fine tuning, ask inverter carved machine always ranging from the time jump out ah?
Suggest you in the inverter power installed a frequency converter input filter, try it, feel a bit like electromagnetic interference caused by frequency converter mistakenly stop ah.
Q:What does "EPCU" mean in a frequency converter?
This is the frequency converter BlueOcean Huateng, they said this code external signal interference, you are not the power line and the signal line to go ah, check the external line, then no problem on the phone to the factory
Q:What are the parameters of the frequency converter? Thank you
Also called torque compensation, in order to compensate for the motor stator winding resistance caused by low-speed torque reduction, and the low frequency range f/V increased method. When the utility model is set as an automatic, the voltage in the acceleration can be automatically raised to compensate the starting torque, and the motor can be accelerated smoothly. If manual compensation is adopted, according to the load characteristics, especially the starting characteristics of the load, the better curve can be selected through the test. For variable torque load, such as improper selection, the output voltage is too high at low speed, while the phenomenon of waste of electricity, and even the emergence of motor load with a large current, while the speed does not go.
Q:What's the use of switching frequency of converter?
Meanwhile, the switching frequency of the converter is adjusted, and the power loss can be adjusted. Because the switching frequency of power loss and inverter power module IGBT is related with the increase in switching frequency inverter and increasing the power loss, this makes the efficiency drop, two is the power module heating increases, is detrimental to the operation, of course work electric converter pressure is high, the power loss also increase effect.
Q:How to maintain the frequency converter will not damage, or regular maintenance?
If the conditions permit, use the oscilloscope to measure the stability of the switching power supply output voltage, such as: 5V, 12V, 15V, 24V and other voltage. Is there any distortion in the square wave of the measuring circuit?. Periodic inspection is recommended and shall be conducted once a year.
Q:How about the quality of ABB converter?
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:How does frequency converter realize variable frequency speed regulation?
The frequency of the electric field is changed, and the frequency of the original fixed 50 Hz is reduced as required, and then the rotation frequency of the induction motor is changed
