Q:What do you mean by the capacity of the inverter and the capacity of the motor?: That's not the case at all"Capacity" and "power" are essentially different. Usually we say that a large transformer capacity is how much KVA, but not to say how much KW, because the two are not the same thing

Q:Which brand of converter is better?: Shanghai Leinuoer recommended! Soft starter and frequency converter products Shanghai Leinuoer company, national key products, Shanghai famous trademark! People's Insurance Company of China quality assurance! Shanghai World Expo Shanghai reyrolle company supporting the project, the Beijing Olympic Games project,

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 is called vector converter?: Vectors and vectors are mathematical methods of vector (vector) analysis, both of which are of the same concept

Q:What is the main function of the frequency converter on the machine tools?: According to the working characteristics of machine tool spindle drive structure, most of the early machine adopts three-phase asynchronous motor with multi-stage gearbox, with the continuous development of technology, machine tool has been greatly improved, so as to put forward new requirements on the spindle system, and because use varies in CNC machine tools, CNC lathe, CNC drilling accounted for 42%. Boring and milling machine CNC grinding machine, punching machine accounted for 33%, accounting for 23%, accounting for 2% of the other, in order to meet the needs of the former two types of CNC machine tools a wide range of large, proposed the following requirements of the spindle drive: main drive motor power range should be 2.2KW~250KW; to have a wide range of stepless speed regulation, such as constant torque speed and 1:10 constant power speed in the range of 1:100~1000; the main transmission requirements are capable of driving the four quadrant; in order to meet the requirements of thread turning, spindle can realize synchronization control and feed.

Q:What does "G" and "P" mean in the converter model?: General inverter said, "G" and "P" type refers to the inverter general type and fan pump difference, G type inverter applies to the general machinery class load, and P type is used in the wind or water pump.

Q:Why does harmonic generator produce harmonic? What's his working principle?: Harmonic generation mechanism of converter outputIn the inverter output loop, the output current signal is a pulse waveform modulated by the PWM carrier signal. For GTR high-power inverter component, the carrier frequency of PWM is 2-3kHz, while the maximum carrier frequency of IGBT high-power inverter component is 15kHz, PWM. Similarly, the output loop current signal can also be decomposed into only the fundamental wave and other harmonics.

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:What does 0L1 stand for?: The acceleration is generally overloaded during acceleration. Load inertia is too large, the inverter power is small, or the acceleration time is too short, and so on

Q:Does the number of inverter settings differ from the number of motor poles, and does it affect the use?: The influence of the inverter on the motor control model, in addition to the speed difference, basically does not affect much
