- 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!
- To solve the problem, then check the original power of the line is loose, the power cables are quickly burnt, after fastening normal, thank you enthusiastic support, thank you!
- 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: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?
- Once the inverter has hardware faults, such as rectifier, inverter circuit and so on. The IGBT module may be damaged, and most of the time it will damage the drive components. The most easily damaged devices are the regulator and the optocoupler. Conversely, components such as capacitance, leakage, breakdown, and optocoupler aging can also cause IGBT modules to burn out or frequency conversion, and output voltage is unbalanced. Check if there is a problem with the drive circuit, and compare the resistance of the trigger terminals when the circuit is not switched on. The voltage waveform at the trigger end can be measured when the power is switched on. However, some inverters are not equipped with modules and can not switch on, when the module P end of the series into a false load, to prevent detection, mistakenly touch the originator or other circuit burned module. In this case, the frequency converter has been seriously damaged (by measuring whether the input and output are short circuited), then there should be special technical personnel maintenance, and generally may not re energized, so as not to expand the scope of failure.
- Q:A control panel I received a photoelectric switch, through the 232 interface connected to the computer, control with a 220V power supply board, computer and inverter when the inverter after the start of the photoelectric switch either do not work or turn off the flash chaos, frequency converter or 232 line open photoelectric switch will be back to normal work. In addition, when the photoelectric switch is powered separately, if the ground wire is connected to the control board, the photoelectric switch does not work. Excuse me, is this interference from the power cord? How to solve?
- Isolation of interference: the so-called interference isolation is the separation of the source of interference from the susceptible part from the circuit so that they do not generate electrical contact. Usually in the power supply and controller and transmitter amplifier circuit, in the power line using isolation transformer, so as to avoid conduction interference, power isolation transformer can use noise isolation transformer.
- Q:What does Ro1c mean on a converter?
- Relay output converter dry contact signal, RO1C is the common end and RO1A is closed, RO1B is normally open, this set of contacts is prepared to run the factory setting output signal, power on self-test is completed can run the relay output signal. It can be modified to the output point of the signal such as fault and operation in the twenty-fourth set of parameters.
- Q:What is the main function of the frequency converter on the machine tools?
- The following example to three inverter in the application of the note for example!CNC machine tool is a kind of flexible and efficient automatic machine tool. It can solve the complicated, precise and small batch processing problem. It is very important to improve the machining accuracy and efficiency of CNC machine tools by rationally controlling the spindle of NC machine tools.
- Q:I would like to ask, the inverter in use in the grid is very high?
- In the process of using inverter, grid voltage fluctuation requirements is not high, the general phase is to allow + 20% fluctuations, three-phase is allowed 15% fluctuations, so most of the grid voltage can be satisfied, unless it is in the countryside, or more remote areas, the voltage change will exceed the allowable value. In addition, the frequency converter on the power grid harmonics also have requirements, if the harmonic content of more than 20%, will lead to frequency converter misoperation, false alarm, more serious circumstances, will lead to inverter out of control, or damage. However, most of the current harmonics will not happen, unless a large number of individual factories use frequency converters, servo, intermediate frequency furnace, welding machine and other equipment.
- Q:What is the over-current of the inverter?
- External cause:?1, the motor load mutation caused by excessive impact, resulting in excessive flow.?2, the motor and motor cable phase or insulation damage to each other, resulting in short circuit turns to the ground, resulting in over-current.?3, over-current fault and motor leakage reactance, motor cable coupling reactance, so choose motor cable must be selected according to requirements.?4. Power factor correction capacitor or surge absorption device on the output side of inverter.?5. When the speed feedback signal is lost or abnormal, it will cause excessive flow, and check the encoder and its cable.
- Q:Does the number of inverter settings differ from the number of motor poles, and does it affect the use?
- Frequency converter has a number of requirements, if the motor is not set by the number of motor parameters, I think there will be the following problems, but may occur, I have not been verified:
- Q:Why does the frequency change when the frequency converter regulates the frequency?
- Because the product of three-phase asynchronous motor stator phase voltage and frequency and flux is proportional to the frequency when the downward adjustment, if the sustain voltage is constant, the flux must be increased, this will cause the main magnetic saturation excitation current passing, the surge in motor damage.As a result, the voltage is usually adjusted down proportionally as the frequency is lowered down.However, when adjusting the frequency, the voltage is not adjustable in order to avoid the excessive voltage damage of the motor. Therefore, in the use of frequency converter overclocking motor, the magnetic flux will decline, the motor output torque characteristics will move to the left.
