- 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: The frequency converter is in use suddenly the speed reduces, then the debugging is out of control, how to do?
- Excessive voltage generation and regenerative braking, the so-called inverter over-voltage, refers to a variety of reasons caused by inverter voltage exceeds the rated voltage, concentrated in the DC bus frequency converter DC voltage. In normal operation, the DC part voltage of converter is the average value after three-phase full wave rectification.
- 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 Ro1c mean on a 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: Why does harmonic generator produce harmonic? What's his working principle?
- The working principle of the inverter is the first AC into DC, because the alternating current is not directly change its frequency, according to the parameter setting of the machine, and then the DC into AC power, and then drag to load.
- 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: How to maintain the frequency converter will not damage, or regular maintenance?
- The correct use method and reasonable maintenance can extend the service life of the inverter to a certain extent. The common maintenance methods of the inverter are cleaning the air filter, cooling the air duct and the interior dust. Check whether the screws, bolts and plug are loose, the input and output reactor ground and interphase resistance is short circuit, the normal should be more than tens of megabytes of europe. The conductor and insulator are corrosion phenomenon, if in time to wipe clean with alcohol.
- 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?
- Excessive temperatureIn addition there are high temperature transducer fault, such as the occurrence of a high temperature alarm, after checking the temperature sensor is normal, may be caused by the disturbance, faults can be shielded, also should check the ventilation fan and inverter. For other types of failures, it is better to contact manufacturers for quick and feasible solutions.
- Q: What is the working principle of a three phase AC asynchronous motor inverter?
- The frequency converter is the electric energy control device that transforms the power frequency power to another frequency by the on-off function of the power semiconductor device. We now use the converter mainly adopts the AC-DC-AC mode (VVVF inverter or variable frequency vector control), the first AC power into DC power supply through the rectifier, then the AC power into DC power supply frequency and voltage can be controlled by the supply of electric motive. The frequency converter circuit is usually composed of rectifier, intermediate DC link, inverter and control of 4 parts. The rectifier is a three-phase bridge controlled rectifier, and the inverter is IGBT three-phase bridge inverter, and the output is PWM waveform. The intermediate DC link is filter, DC energy storage and buffer reactive power.
- Q: Delta inverter fault output which parameter is set?
- Overvoltage overvoltage fault of inverter DC bus voltage on the tributaries. Under normal circumstances, the average DC inverter three-phase full wave rectifier after. If 380V line voltage calculation, the average DC voltage Ud= = 513V. 1.35 U line in the overvoltage occurs when the DC bus capacitor will be when the charging voltage to about 760V, inverter over-voltage protection action. Therefore, inverter, have a normal range of working voltage, when the voltage of the inverter is likely to damage more than this range, there are two types of common overvoltage.
