Q: Application of ABB frequency converter: What is the difference between a voltage type and an electric current type?The main circuit of the inverter can be divided into two categories: voltage is DC voltage source converter for AC inverter, the DC circuit is the filter capacitor current is DC converter; current source for AC inverter, the DC circuit filter inductance stone.

Q: How does the frequency converter fit the brake unit and the brake resistor?!: To calculate how much energy consumption, can be converted into electric current, to select the brake unit. You can also choose the braking resistance (to consider resistance temperature characteristics to choose), then select the brake unit with matching (see manufacturer manual).

Q: What is the function of a frequency converter on an electric motor?: Through the frequency converter, the motor can be adjusted speed, so as to obtain the speed required by itself, and also can reduce the motor running current and save energy and reduce consumption.

Q: How do two inverters synchronize?: First of all, to determine whether the speed of the two conveyor is very strict (there is strict relative position requirements), if not, can use the following program:1. use a double potentiometer to tune two inverters simultaneously, one with a potentiometer to adjust the ratio between the two.

Q: What is the frequency converter through function?: Frequency converter is an ideal motor stepless speed regulating device. It is mainly used in three-phase and two-phase asynchronous motors. It has the advantages of small start-up current, smooth operation and complete protection facilities. The utility model is suitable for stepless speed regulation of various equipment.

Q: How can I control the frequency converter with a computer?: The commonly used PLC and DCS control system in industrial area are applicable to the conditions of inverter interface control module, can realize the closed-loop converter convenient automatic control in the control system, widely used in large and medium. The control device for some smallexperimental device and embedded processor in inverter control, generally also need to deal with the keyboard input, display, data acquisition and other work such as process control, this control is more suitable for single-chip control system as the core, and uses PLC and operation panel, it can achieve the function but the cost is too high. Should not be used.

Q: 5.5KW frequency converter with 4.5KW deep water pump, pressure regulator by conveying signal to frequency converter start normal, the pressure to reduce the frequency converter after the start, to about 30Hz in order to maintain the pressure about shocks, 30 seconds inverter over-current alarm. Can it be the fault of the frequency converter? How should I check it?: Once the inverter has hardware faults, such as rectifier, inverter circuit and so on. The IGBT module may be damaged, and most of the time it will damage the drive components. The most easily damaged devices are the regulator and the optocoupler. Conversely, components such as capacitance, leakage, breakdown, and optocoupler aging can also cause IGBT modules to burn out or frequency conversion, and output voltage is unbalanced. Check if there is a problem with the drive circuit, and compare the resistance of the trigger terminals when the circuit is not switched on. The voltage waveform at the trigger end can be measured when the power is switched on. However, some inverters are not equipped with modules and can not switch on, when the module P end of the series into a false load, to prevent detection, mistakenly touch the originator or other circuit burned module. In this case, the frequency converter has been seriously damaged (by measuring whether the input and output are short circuited), then there should be special technical personnel maintenance, and generally may not re energized, so as not to expand the scope of failure.

Q: What are the basis of the frequency converter to choose?: 1. the power of the inverter is selected according to the load power. How many power motors should be chosen for a multi power motor?. Size one is ok.2. frequency converter model, different uses, choose different frequency converter. For example, there are general frequency converter, fan, water pump dedicated inverter, a machine tool spindle dedicated inverter. Wait。3. when the load is large, the braking unit and the braking resistor should be selected simultaneously.4. check the motor nameplate current rating (no nameplate rated current). The rated current of the inverter is greater than the maximum running current of the motor

Q: What's the difference between universal inverter and fan pump converter?: Fan and pump load:In a variety of fans, pumps, oil pumps, with the rotation of the impeller, the air or liquid within a certain speed range of resistance is roughly proportional to the speed of the 2 side of the n. As the speed decreases, the torque decreases by 2 times the speed. The power required for this kind of load is proportional to the 3 power of the velocity. When the required air volume and flow rate are reduced, the frequency and speed of air flow can be regulated by the frequency converter, so the energy can be saved substantially. Because the power required at high speed increases with the speed, and is proportional to the speed of the three side, so the fan and pump load should not be used in the ultra power frequency operation

Q: Frequency converter OC alarm, what's the matter?: The frequency at which the OC fault occurs in all faults of the inverter may be the highest and the most frequent. In the process of starting the alarm, in the process of stopping the alarm, alarm in operation, so that power on the alert, and even with other fault codes or currentIndirectly tell you that there is a OC fault in this inverter!
