Q:There is much dust and moisture in my workshop. Many brands are not durable.: ABB inverter is of high quality, but it requires a lot of environment, such as dust and humidity in your workshop. It is too bad for ABB inverters. You can try to use the seal of inverter, it is designed according to the use environment of inverter in various industries, mainly considering China's current converter relatively harsh environment (water vapor, dust, oil, metal powder, corrosive gas), in CNC lathe, grinding machine chemical plant, reaction kettle, blender, textile machinery, printing and dyeing equipment, water pump, industrial washing machine, dehydration machine where the effect is very good.

Q:What are the benefits of installing economizer in industrial enterprises?: 1, through the intelligent online detection control system, closed-loop control can be completed, to keep track of changes in the load, load, change the machine output parameters, meet the requirements of the production process for customers, when customers need full load motor, motor output is not enough.For example: a plant water pump, motor speed can be supplied to a 100 force, the force is now 80, with the inverter directly to the 20 removed, and if the production process of the customer needs to provide 100 force, there will be a lack of motivation, affect the customer's production process and product quality. Such as the installation of our power class Saver, will not be the case, it can change the parameters at any time according to the requirements of the load, to ensure the normal supply of power.

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: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: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:What are the parameters of the frequency converter? Thank you: That is to say, the upper and lower amplitudes of the output frequency of the inverter. Frequency * * is to prevent misoperation or external frequency set signal source failure, resulting in the output frequency is too high or too low, in order to prevent damage to a device protection function. In the application, according to the actual situation can be set. This function can also be used as a speed limit, if the conveyor belt, the conveying material is not too much, to reduce the mechanical and wear belts, be driven by inverter, and the inverter upper frequency settings for a particular frequency, so it can make the belt conveyor running on a fixed low speed work

Q:What does "frequency" in household appliances mean?: The air conditioner use frequency, enlarge the working range of the compressor, the compressor does not require intermittent running can be realized in cold and warm control, to reduce power consumption due to temperature changes, eliminate discomfort. In recent years, the new type of air conditioner has adopted brushless DC motor to realize variable frequency speed regulation, and its energy-saving effect is about 10% - 15% higher than that of AC asynchronous motor frequency conversion. In order to further improve the efficiency of the device,

Q:What does Ro1c mean on a converter?: Relay output converter dry contact signal, RO1C is the common end and RO1A is closed, RO1B is normally open, this set of contacts is prepared to run the factory setting output signal, power on self-test is completed can run the relay output signal. It can be modified to the output point of the signal such as fault and operation in the twenty-fourth set of parameters.

Q:What does a frequency converter do?: Mainly used to drive AC motors, AC motors to achieve stepless speed regulation.For example, for the fan, with frequency converter to adjust the speed of the motor speed, you can change the size of the air supply.There are many occasions that need speed regulation. Using frequency converter to speed up is simple and energy-saving.

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.
