Q:What is the frequency converter through function?: Inverter through function refers to:The converter can temporary loss of power in the power grid when using mechanical transducer can keep running, as long as the rotation of the motor and the inverter to provide energy, although the speed will decrease, but the converter will run normally (power mode), and if the grid connected inverter in state grid voltage recovery after the inverter can be immediately put into normal electric state.

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 inverter (power converter, Power Inverter) is a kind of DC12V can be converted to DC and AC220V AC power the same, for general use of electrical appliances, power converter with a convenient car.

Q:Is the voltage low? The younger brother is bored to death, no problem with the wire drawing machine, the full load will jump off. Display frequency converter overload and acceleration operation overcurrent. Help me please.: When detecting the phase - lacking circuit, the phase - blank board is directly tested, and the PL signal on the drive board is normal. Normally, the PL is low, the phase is Fang Bo, and the power is high when the power is switched off. It is important to note that the PL signal output by the drive board or the phase blank panel is not sent to the CPU after the level switch has been passed on the main control board, and it should be noted that the fault is caused by the main board or the missing phase board during maintenance.

Q:The frequency converter works with sharp noises. What's the process of converting electrical energy into mechanical energy?. The mechanism of sound making. Thank you: There is a sharp sound can only prove that you have problems with frequency conversion, frequency conversion stable operation can only hear the sound of the fan slightly. Although we are engaged in frequency conversion, but let me tell you this mechanism, really can not say, you can use frequency conversion, and play to his limit, have been very difficult.

Q:How to choose frequency converter?: Frequency converter (Variable-frequency, Drive, VFD) is the application of frequency conversion technology and microelectronics technology, by changing the power supply frequency of the motor to control AC motor power control equipment. The frequency converter is mainly composed of rectifier (AC DC converter), filter, inverter (DC AC converter), brake unit, drive unit, detection unit, micro processing unit and so on.

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:How to deal with the fault Yaskawa inverter GF: This problem most likely. While G7 or F7 are generally Holzer Holzer sensor, sensor due to temperature. The influence of environmental factors such as humidity, work is easy to drift, to report "GF", another reason may be: E2-01 improper setting may also reported GF fault.

Q:Knowledge, principle and operation method of frequency converter.: The three major parts of the working principle of frequency converter:This is how the inverter works, but how does it work? Mainly composed of three components. (1) convert the power frequency power to the rectifier of the DC power: it transforms the power frequency power into the DC power supply. A reversible converter can also be constructed using two sets of transistor converters, which can be regenerated for their reversible power direction. (2) absorption in the converter and inverter voltage generated by the pulsating "flat wave circuit" in the rectifier DC voltage is rectified, ripple voltage with power frequency 6 times, in addition the pulsating current generated by the inverter to the DC voltage fluctuation. (3) the DC power conversion for AC power rectifier with "inverter": instead, the inverter is DC power converter for AC power required frequency, to the time the 6 switch off, you can get 3 phase AC output.

Q:How do you understand the ramp up (descent) time of the inverter? Thank you!: The ramp up time is to start from the 0 speed, inverter, running to reach the given speed (for example: 1420) the time required, in general, the longer the time, the frequency converter and motor impact is small. In the actual work process, according to process requirements to set the length of time. (more than 10-15 seconds) or so, if it is a pump or fan motor, do not need to change its rise time, the default can.
