Q:How do you set the frequency with panels?. What are the specific steps?: Frequency converter is the application of frequency conversion technology and micro electronics 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. Inverter by internal IGBT drive voltage and frequency off to adjust the output power, the power supply voltage required to provide according to the actual needs of the motor, so as to achieve the purpose of speed, energy saving, in addition, there are a lot of protection drive, such as over-current, over-voltage, overload protection and so on. With the continuous improvement of the degree of industrial automation, inverter has also been widely used.

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: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:What are the benefits of installing economizer in industrial enterprises?: Frequency converter is a device that regulates the speed of an electric motor by adjusting the output frequency:1. The frequency converter can only reduce the motor speed by reducing the power supply frequency. The application environment is limited and the automatic control function is not available. It can not be used in many load changing occasions;Have a lot of 2 odd harmonics, frequency converter operation, it will seriously affect other equipment life and efficiency, at the same time use but also affect other precision control of the equipment in the factory, such as computer, automatic control system, monitoring system and so on;3 、 frequency converter serial access to the customer's low-voltage power system, the power supply of the customer security risks.

Q:What do you mean by the capacity of the inverter and the capacity of the motor?: Capacity can be understood as active power + reactive power, such as the capacity of 100KVA inverter, is not 100KW motor,

Q:What does "EPCU" mean in a frequency converter?: But look at your inverter has also been used for some time, if not before, and now appear, it is estimated that the hardware is broken, and manufacturers communicate maintenance!

Q:Electronic governor for single-phase motor speed control, frequency converter for three-phase motor speed regulation, what are their differences in speed control effect? How does the frequency converter adjust speed? Can you give me an example?: Is the original power inverter direct input three-phase asynchronous motor inverter in inverter internal access first, through PWM electronic converter technology will AC rectifier, inverter, a controllable frequency alternating current at the input to the motor, the motor operation can be controlled by V/F, output torque control and vector control control frequency, change the loop current, realize energy-saving operation, especially the energy saving effect is obvious in the motor at light load is a kind of energy-saving products, has been widely spread and applied.

Q:What's the function of this brake unit?: When the motor is fast stopping, the motor will feedback the energy to the converter, causing the DC bus voltage to rise or even damage the IGBT. Therefore, it is necessary to use the braking unit to save the part of the energy to protect the converter.Inverter braking a lot, can refer to:

Q:What role does input and output reactor play?: Enter the reactor to suppress the surge voltage and surge current protection, frequency converter, and prolong its service life and prevent the harmonic interference, at the same time as the speed control inverter adopts frequency conversion mode, so often produce harmonics and waveform distortion in the speed, will affect the normal use of equipment, therefore, should be installed in a line choke the input end of the inverter can improve the power factor and harmonic current suppression filter, harmonic voltage and harmonic current, improve the quality of power grid.

Q:What is the difference between a frequency converter and a servo controller?: Servo motor servomotorAutomatic control of micro motor actuator device used for. Executive motor. Its function is to convert electrical signals into angular or angular velocities of rotating shafts.Servo motors are divided into two categories: DC and dc. AC servo motors work in the same way as AC induction motors. Wf excitation winding and control winding WcoWf is connected to a constant AC voltage of two phase space displacement electric angle of 90 degrees on the stator, the change of Wc on AC voltage or phase is applied to achieve the purpose of running motor control. AC servo motor with stable operation, good controllability, fast response, high sensitivity and mechanical properties and nonlinear adjustment characteristic index (strict requirements are less than 10% and less than 15% ~ 15% ~ 25%) etc.. The principle of DC servo motor is the same as that of general DC motor. The motor speed is n
