Q:Can a power converter be used in a motor with small power? Will it burn the motor?: Yes, the motor will not burn, if it is a small power converter, with large power motor, frequency converter will burn point

Q:What's the frequency converter for? What does it look like?: The inverter is mainly used in industrial equipment, such as power plants, water plants, water supply equipment, large pumping station, it is basically a cuboid, a digital display control panel; and in the English show types into the universal type, fan pump type, vector control, different types should be used in different working conditions, voltage grade from 220V-10 million volts.

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?: Method for solving interference caused by frequency converter:Adopt software anti-interference measures: specifically, the carrier frequency of the inverter is lowered through the man-machine interface of the inverter, and the value is reduced to an appropriate range. If this approach does not work, then only the following hardware anti-interference measures can be taken.Carry out the correct grounding: through the field investigation, we can see that the site of the ground is not ideal. The correct grounding can not only effectively suppress external interference, but also reduce the interference of the equipment itself to the outside. It is the most effective measure to solve the interference of frequency converter.

Q:What does the RUN key on the inverter mean? How do you use it?: When selecting panel operations (when the panel of the inverter is the control source of the inverter), it is the meaning of the "running" button.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. The inverter adjusts the voltage and frequency of the output power by disconnecting the internal IGBT

Q:How do you set the frequency with panels?. What are the specific steps?: The parameter 700 is the starting signal, the 1 is a panel key starting, and the 2 is an external signal starting;The parameter 1000 is the frequency setting value, and the 1 is a panel lifting key, and the frequency is changed, and 2 is changed by the external analog signal.Your problem, the start signal is set up, finished, the parameter 1000 should be 1, so that the panel set frequency, and then set the parameter 1031 to 1, so that it automatically save the frequency changes after the value

Q:High-voltage converterGeneral inverterPump frequency converterEngineering frequency converterCould you tell me some frequency converter according to the class?: Specific answer to your question: 1, high voltage inverter: This is based on the input voltage level terms. Generally speaking, 10KV is more than 6KV voltage high voltage frequency converter, 1140V, 3300V in general is medium (some people also called it the high voltage level of 380V, 660V), 480V, commonly called the low-voltage inverter; 2, pump inverter: This is according to the type of application in terms of. Fan pump inverter mainly refers to the frequency converter used to drag fans, pump load, the main feature is light load, simple application.

Q:How do two inverters synchronize?: First of all, to determine whether the speed of the two conveyor is very strict (there is strict relative position requirements), if not, can use the following program:1. use a double potentiometer to tune two inverters simultaneously, one with a potentiometer to adjust the ratio between the two.

Q:Frequency converter, fault, contact action: The frequency converter has 1-2 relay outputs, that is, digital output. By default, most of the output of the fault is the relay. The general definition of the 2 relays is defined as a running output and a fault output.This contact output and inverter circuit inside the electrical isolation, can use 24V, you can use 220V, you can use any lower than the voltage level of 500V to use this contact, according to the actual needs of love then why.

Q:Can the motor with frequency converter directly wave the insulation?: The use of motor inverter drive, if the measurement will not disconnect the motor and inverter, tramegger issued a "high voltage" will spread through the winding inverter inside, will lead to some components breakdown within the inverter a damaged, because some components although the internal current is higher but the degree of pressure will be very limitedTherefore, in shaking the test of the use of inverter motor insulation, the inverter and motor connection is broken after the start, you can ensure that the frequency converter will not be damaged.

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.
