Q:What does "G" and "P" mean in the converter model?: G stands for constant torque, usually overloadedP stands for torque change, usually light load type

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.

Q:What's the difference between universal inverter and fan pump converter?: In practice, the production machinery is often divided into three types: constant torque load, constant power load and fan, pump load.Constant torque load:The load torque TL is independent of the speed n, and the TL remains constant or almost constant at any speed. For example, conveyor belts, mixers, extruders and other friction loads, as well as cranes, hoists and other potential loads are constant torque load.When the inverter drives the load with constant torque, the torque at low speed is large enough and has enough overload capacity. If it is necessary to operate at a low speed, the cooling capacity of the standard asynchronous motor should be taken into consideration, so as to avoid the excessive temperature rise of the motor.

Q:Heating inverter commissioning steps: And carry on the test run 1. manual operation of the frequency converter panel running stop, observe the motor running process and the frequency converter display window, to see if there is abnormal phenomenon. 2. if the P is started and the over-current protection is stopped in the motor, the acceleration P deceleration time should be reset. The acceleration of the motor during acceleration and deceleration depends on the acceleration torque, while the frequency change rate of the inverter during the start and braking is set by the user. If the inertia of motor or motor load change, speed or deceleration rate according to frequency change preset when possible acceleration torque is not enough, resulting in motor stall, motor speed and the inverter output frequency coordination, thus causing overcurrent or overvoltage. Therefore, it is necessary to set acceleration and deceleration time according to the inertia and load of the motor, so that the frequency change rate of the converter can be coordinated with the speed change rate of the motor.

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,: One can be controlled by a potentiometer, the other can track the first torque can be achieved, and general general frequency converter has this function

Q:What does the RUN key on the inverter mean? How do you use it?: According to the actual needs of the motor to provide the required power supply voltage, and then to achieve energy saving, speed control purposes, in addition, there are many inverter protection functions, such as over-current, overvoltage, overload protection, etc.. With the continuous improvement of the degree of industrial automation, inverter has also been widely used.

Q:High-voltage converterGeneral inverterPump frequency converterEngineering frequency converterCould you tell me some frequency converter according to the class?: According to the classification of link Transformation: (1) the AC-DC-AC converter is the first AC into DC rectifier through, and then transformed into the frequency DC voltage adjustable AC inverter, also known as indirect, is currently widely used general-purpose inverter. (2) can be divided into cycloconverter, is directly converted into AC voltage adjustable frequency AC, also known as direct inverter DC power supply according to the classification of properties: (1) the voltage type inverter voltage type inverter is characteristic of DC link energy storage device using a large capacitor load reactive power will be it is to buffer the DC voltage, DC power supply is relatively stable, smaller internal resistance and the equivalent voltage source, so that the voltage type inverter, are often used for load voltage changes in the larger situation. (2) current inverter current type inverter is characterized by large DC link inductance as a storage buffer of reactive power, which changes the current control, the voltage is close to sine wave, because the DC resistance is large, so that the current source converter (current). The characteristics of current source inverter (advantages) can restrain the load current is frequent and rapid changes.

Q:Schneider 303 4KW frequency converter F 013 trouble shooting method: If the converter is overloaded, it is recommended to check the set acceleration time and whether the load is blocked or not.

Q:Why does harmonic generator produce harmonic? What's his working principle?: The working principle of the inverter is the first AC into DC, because the alternating current is not directly change its frequency, according to the parameter setting of the machine, and then the DC into AC power, and then drag to load.

Q:What is a frequency converter?: There are many classifications of inverter, the main circuit according to the classification, can be divided into voltage type inverter and current source inverter; switching mode in accordance with the classification, can be divided into PAM control inverter, PWM control frequency and high frequency PWM inverter control; in accordance with the principle of classification, can be divided into V/f control inverter, slip frequency control inverter and vector control inverter; according to use classification, can be divided into general inverter, high performance inverter, high frequency inverter, single-phase inverter and three-phase inverter.
