Q: Application of ABB frequency converter: What is the starting current and starting torque of the motor when the inverter is in operation?Using frequency converter operation, with the acceleration of the motor, accordingly improve the frequency and voltage, the starting current is limited to 150% rated current (according to the type of machine is 125%~200%). The starting current is 6~7 times of direct starting with the mains frequency power supply, so the mechanical and electrical impact will be produced. It can start smoothly with frequency converter (longer starting time). The starting current is 1.2~1.5 times the rated current, the starting torque is 70%~120%, the rated torque; for the inverter with automatic torque enhancement, the starting torque is above 100%, and the full load can start.

Q: How does the frequency converter change the voltage and change the speed of the motor?: The frequency converter regulates the speed of the motor, mainly by changing the frequency. The frequency determines the synchronous speed of the motor, and the speed of the motor can be lowered by reducing the frequency.

Q: Knowledge, principle and operation method of frequency converter.: The three major parts of the working principle of frequency converter:This is how the inverter works, but how does it work? Mainly composed of three components. (1) convert the power frequency power to the rectifier of the DC power: it transforms the power frequency power into the DC power supply. A reversible converter can also be constructed using two sets of transistor converters, which can be regenerated for their reversible power direction. (2) absorption in the converter and inverter voltage generated by the pulsating "flat wave circuit" in the rectifier DC voltage is rectified, ripple voltage with power frequency 6 times, in addition the pulsating current generated by the inverter to the DC voltage fluctuation. (3) the DC power conversion for AC power rectifier with "inverter": instead, the inverter is DC power converter for AC power required frequency, to the time the 6 switch off, you can get 3 phase AC output.

Q: How does frequency converter realize variable frequency speed regulation?: The technique of alternating current control by changing the frequency of alternating current is called frequency conversion technology. The frequency converter usually uses the on-off function of the power semiconductor device to change the power frequency power to another frequency energy control device.

Q: How do two inverters synchronize?: One potentiometer is used to control one of the inverters, and then the analog output of the inverter is used to control another inverter, and a potentiometer is added to the middle of the converter to adjust the proportion.

Q: Does the number of inverter settings differ from the number of motor poles, and does it affect the use?: When the number of poles of the motor is corresponding to the speed of the motor and the number of the poles is not set, the speed is controlled, and the speed is very difficult to drive.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. 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: The frequency converter works with sharp noises. What's the process of converting electrical energy into mechanical energy?. The mechanism of sound making. Thank you: There is a sharp sound can only prove that you have problems with frequency conversion, frequency conversion stable operation can only hear the sound of the fan slightly. Although we are engaged in frequency conversion, but let me tell you this mechanism, really can not say, you can use frequency conversion, and play to his limit, have been very difficult.

Q: Heating inverter commissioning steps: The no-load connection test of the frequency converter will connect the grounding terminal of the frequency converter to the ground 1. 2 the power input terminal of the frequency converter is connected to the power supply through the leakage protection switch. 3 check the frequency converter display window factory display is normal, if not correct, should reset, or request exchange. 4 familiar with the operation key of frequency converter. The inverter has run in general (RUN) and stop (STOP), programming (PROG), P (DATAPENTER), the data confirm the increased (UP, 3), reduce (DOWN, 6) and other key definitions of different inverter operation keys are basically the same. In addition, some inverters also monitor (MONITORPDISPLAY), reset (RESET), inch movement (JOG), shift (SHIFT) and other functional keys.

Q: Can a power converter be used in a motor with small power? Will it burn the motor?: Yes, the motor will not burn, if it is a small power converter, with large power motor, frequency converter will burn point

Q: Frequency converter OC alarm, what's the matter?: Description of the OC fault in the inverter manual, following several explanations: the load side short-circuit current greater than OC, run jump failure is two times; the output of the inverter module circuit; current transducer; overload; acceleration and deceleration time is too shortEtc.. Some models do not use OC to mark such faults. They are explained by load side short circuit, frequency converter overload, serious ground fault and so on. This is of course the alias of OC fault.
