Q:What is the frequency converter through function?: Frequency converter is an ideal motor stepless speed regulating device. It is mainly used in three-phase and two-phase asynchronous motors. It has the advantages of small start-up current, smooth operation and complete protection facilities. The utility model is suitable for stepless speed regulation of various equipment.

Q:There is a feed and send system. Now due to the severity of the material is not the same as the two converters often change speed, the workers do not understand their own, often by, often bad now how to use the best way you can use a potentiometer or other method, control of the two frequency converter, synchronous operation. Is to adjust one, and the other also with the kind of frequency, so that you can let the workers themselves to open, and the two inverters, the same manufacturer, the same model, the same load,: What kind of communication mode does the frequency converter support? Generally speaking, it is more accurate to communicate by means of synchronization. Expensive。The main transformer potentiometer, from the analog frequency converter, may be 1, the lag will be greater than 2, analog may have a larger error, 3, analog may be subject to interference. The cheapest。You can also use synchronous controller, analog input, the two roads as the same analog, cheaper, more reliable synchronization, may be disturbed.

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.: The difference between the display value and the measured value shows that the bus detection circuit is abnormal if the deviation is larger. Conversely, if the two value deviation is minimal or equal, the missing phase signal is abnormal. At present, there are two kinds of bus detection circuit used in our company: resistance voltage divider and operation comparison amplification (TL082). Corresponding to the detection circuit output 0 - 3.3V corresponds to the actual bus 0 - 1000V, the two circuits are relatively simple, maintenance only need to test the key point voltage in the circuit, you can easily find the fault point.

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: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:Where is the frequency converter used?: In these industries, the use of small and medium power converters more, 220V/380V as its main model. Of course, the auxiliary facilities in these industries still have fans, pumps and inverters, but they don't use much.

Q:What is called vector converter?: In the electrical field is mainly used for the analysis of AC power, such as the analysis of the motor, etc., in the application of inverter in motor analysis based on the theory of frequency control, called vector control inverter, the method is not unique, but a basic mathematical model.

Q:What is the difference between SIEMENS inverter and built-in filter?: SIEMENS built-in filter optional three. Class a EMC filter. B class EMC filter. LC/ sine filter.Power 110KW to 250KW converter, optional external or built-in level a filter,The power 7.5KW to 15Kw converter, in addition to additional B class EMC filter, can be equipped with a class EMC filter.The LC/ sinusoidal filter can effectively suppress the rise of voltage and capacitance charge / discharge current in the variable frequency drive. But there are many restrictions: only V/F is allowed. FCC control mode. To comply with the 15% drop capacity, the output frequency limit is 150HZ, and only allowed to operate at the 4KHZ pulse frequency. In operation and debugging, the LC sinusoidal filter must be connected to the motor.

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?: Shielded interference source: shielded interference source is an effective way to suppress interference. Usually the inverter itself with iron shielding, can not let the leaked electromagnetic interference, but the output line frequency converter is best to use steel shielding, in particular to an external signal (4~20mA signal output from the controller) control of inverter, the control signal line is as short as possible (usually less than 20m), and must use the shielded twisted pair and the main power line and the control line (AC380) and (AC220V) completely separated. In addition, the circuit of electronic sensitive equipment in the system also adopts shielded twisted pair, especially the pressure signal. All signal lines in the system must not be placed in the same pipe or slot as the main electrical line and control line. To make the shield effective, the shield must be grounded reliably.

Q:What is the TTK converter produced?: Characteristic：Compact structure design, flexible installation, advanced control algorithm: space voltage vector control technology, power failure restart, automatic voltage adjustment, dead time compensation, energy saving operation,The main and auxiliary setting, built-in PID, simple PLC, oscillating frequency and zero frequency difference, length control, precision control requirements; design and test in accordance with international standards, to ensure the reliability of the product; choose rich accessories.
