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: 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, currently has the localization.

Q: What's the function of this brake unit?: The normal asynchronous motor in power loss, but also because of the inertia and load rotor rotate continuously for a period of time, at this time, due to the current of the rotor motor will still exist, such as the generator, sent to the power supply current. When a short circuit fault occurs, the motor also provides feedback current.

Q: Why do you install these things? Our factory has 380220 points. Then we plant in addition to high voltage motor, the other are 380 of the motor, then what's the use of these two things?: Asynchronous motor is the torque between the current flowing through the motor flux and rotor as a result of the interaction, at rated frequency, but only if the voltage will reduce the frequency, then the magnetic flux on a large magnetic circuit saturation, the motor will be seriously burned. Therefore, the frequency and voltage should be changed proportionally, that is to say, to change the frequency, to control the output voltage of the converter at the same time, to keep the flux of the motor to be certain, and to avoid the occurrence of the weakening of the magnetic flux and the saturation of the magnetic flux. This control mode is mostly used in fans, pumps and energy saving inverters. The frequency changer changes the voltage, must change the frequency

Q: Where is the frequency converter used?: The machinery manufacturing industry, including: elevator, automobile, textile, printing and packaging, paper making, hoisting machinery, food, tobacco, etc. the use of these pumps, inverter industry is mainly in electrical equipment, control and obtain the best product performance and output rate is the main purpose of energy saving is different from the 1 in

Q: The difference between soft starter and converter: The soft starter is during the start-up of the equipment to take blood pressure or other ways to reduce the starting current of the inverter machine, the device is in operation according to the equipment load by changing the size of the power frequency and regulating equipment output.

Q: Does the number of inverter settings differ from the number of motor poles, and does it affect the use?: 1. motor speed control will not be accurate2. the working current of the motor may become larger, and the motor will be burnt out3., excitation what will change, but also may cause the motor heating, burnout, will also reduce the efficiency of the motor;4. may also burn the inverter.5. motor output may be affected.

Q: What are the benefits of installing economizer in industrial enterprises?: The input and output filter and the DC reactor in the economizer can prevent the harmonic produced by the converter and cause the pollution of the power grid and the surrounding electricity environment.3 、 no disturbance power supply / electricity saving conversion system is beneficial to ensure that the customer load can be put into use quickly when the machine fails, and the normal production of the customer will not be affected. At the same time, the protection function of the economizer is perfect, and it has the protection function of over voltage, under voltage, over current, over temperature and surge resistance.4, reactive power compensation, improve the power factor of the system, reduce reactive power loss.

Q: There is much dust and moisture in my workshop. Many brands are not durable.: You can't do anything like this! Dust will fall on the circuit board and cause short circuit of the component. The same humidity.Suggest to strengthen the protection level of cabinet. But heat must be taken into account. Or make an independent electrical room. Install air-conditioning. As God offered!

Q: What is the frequency converter AVR?: When the input voltage deviation from the rated value, the function can keep the output voltage constant, so under normal circumstances should be AVR action, especially when the input voltage is higher than the rated value, to protect the motor from excessive voltage caused by long-term insulation damage or high magnetic density caused by excessive heating core.
