- Q: At the base block Yaskawa inverter is what reason?
- Garbage in Yaskawa signal board on the small line contact oxidation, look good, this is a kind of weak signal, and for safety relay is not the safety loop at high levels in a small line short circuit, 1000 Yaskawa A factory is shorted for a long time have blocked the oxidation base
- 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: How does the PLC process the inverter output signal?
- Frequency converter frequency signal will actually be converted to 4-20mA signal output, access to the PLC AI channel, SIEMENS 200 PLC, some CPU module comes with AI input, but also has a dedicated AI expansion module. What's left is software programming
- 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: Today, I was asked the question, and I also brought it to you to share the following Oh!
- The frequency of the electricity we use everyday is 50Hz. If we want to change the frequency, we have to change it through the frequency converter.The working principle of frequency converter is to change the frequency alternating current into no frequency direct current, and then control it by electronic circuit so that it can adjust its frequency alternating current at any time.The inverter is similar to the back half of the inverter, which converts the direct current into alternating current.
- Q: How much is the motor 90KW and the frequency converter selected?Colleagues suggest 110W?The cost will be higherIs it okay to choose 90KW?
- Should be able to, in the design of the inverter in consideration of the corresponding motor power matching. Choose a large capacity, a little waste Oh! Our company choose frequency converter is one-to-one correspondence, did not choose the large capacity.
- Q: Can 220V use frequency converter to drive three-phase motor with 380V?
- Can not. The inverter is not step-up, single-phase 220V AC frequency converter into it is three-phase 220V AC motor is connected if your star angle connection can be changed, if the corner there's no way, after the motor power will be reduced about 4/10.
- Q: 5.5KW frequency converter with 4.5KW deep water pump, pressure regulator by conveying signal to frequency converter start normal, the pressure to reduce the frequency converter after the start, to about 30Hz in order to maintain the pressure about shocks, 30 seconds inverter over-current alarm. Can it be the fault of the frequency converter? How should I check it?
- UndervoltageThere is a problem with the power input circuit. It may be caused by serious overloading of the line or bad contact with the line. The letter "E" PMU display panel LCD screen SIEMENS 6SE70 series inverter, the inverter can not work, press the P button and to stop transmission are invalid, check the operation manual and the related introduction, in the external DC24V power supply, that is low voltage, solution, inverter working.
- Q: What is the main harmonic produced by a transducer? How about the degree?
- The frequency converter is a nonlinear load, which absorbs nonsinusoidal current from the grid and causes the voltage distortion of the network. It is not only a harmonic source, but also a harmonic receiver. As harmonic source, it has different influence on all kinds of electric equipment, automatic device, computer, measuring instrument and communication system. As for the power supply line, due to the harmonic effect, the quality index of the power grid is deteriorated, the reliability of the power grid is reduced, the loss of the power grid is increased, and the service life of the electric equipment is shortened.
- Q: Delta inverter fault output which parameter is set?
- 1 undervoltage show that the inverter power input part of the problem, you need to check before you can run. ?5.2, the temperature is too high, such as motor temperature detection device, check the cooling situation of the motor; inverter temperature is too high, check the frequency converter ventilation.
