Q: Application of ABB frequency converter: What are the differences between PWM and PAM?PWM is English Pulse Width Modulation (pulse width modulation), according to the law must change the pulse of the pulse width in a tone adjustment output and waveform.PAM is the abbreviation of Pulse Amplitude Modulation (pulse amplitude modulation) in English. It is a modulation way to change the pulse amplitude of pulse column according to a certain rule to regulate the output value and waveform.

Q: At the base block Yaskawa inverter is what reason?: Garbage in Yaskawa signal board on the small line contact oxidation, look good, this is a kind of weak signal, and for safety relay is not the safety loop at high levels in a small line short circuit, 1000 Yaskawa A factory is shorted for a long time have blocked the oxidation base

Q: Knowledge, principle and operation method of frequency converter.: Summary of the working principle of frequency converter:Before the work principle of frequency converter is understood, it may be possible to see why the inverter is sacred first Inverter is the frequency power supply (50Hz or 60Hz) converted to various frequency AC power supply, in order to realize the motor speed change operation of equipment. The control circuit controls the main circuit of the rectifier circuit will be converted into AC DC, DC intermediate circuit of the rectifier output smoothing filter, inverter circuit to DC and then reverse into alternating current (and core control circuit: AC - DC - AC the process). And the frequency conversion technology should be born with the need of AC motor stepless speed regulation. The working principle of formula to express the words is: n = 60 f (1 s) /p (1) - N - speed asynchronous motor; F -- asynchronous motor frequency; s - motor slip; P - pole motor. By formula (1), the speed n is proportional to the frequency f. As long as the frequency of F can be changed, the speed of the motor can be changed. When the frequency f changes within the range of 0 to 50Hz, the speed range of the motor is very wide. Frequency converter is to change the frequency of motor power to achieve speed regulation, is an ideal high efficiency, high performance speed control means.

Q: Not to say that the inverter speed is mainly down frequency, how can I see the frequency rise to 60HZ, so that the three-phase motor is not more than the rated speed?: Mainly below the basic frequency of speed regulation,If higher than the basic frequency, that is constant power speed, that is, the higher the motor speed, the smaller the torque

Q: Where is the difference between soft starter and converter?: The soft starter changes the supply voltage only and is equivalent to a step-down starter. The frequency converter is much more complex and much more expensive than the soft starter. The inverter also has a soft start function, which is achieved by changing the power frequency. Difference between high voltage starter and low voltage starterThe main circuit of the soft starter is thyristor, and the start-up process is completed by gradually changing the turn-on angle of the thyristor. This is the basic principle of the soft starter. In the low-voltage soft starter market, a wide range of products, but high voltage soft starter products are still relatively small. High voltage soft starter is the same as low voltage soft starter, but there are some particularities in high voltage soft starter and low voltage soft starter:

Q: Why does the frequency change when the frequency converter regulates the frequency?: That's for sure. The curve of voltage and frequency should be set according to the load condition, but after the rated frequency of the motor, the voltage is kept at the rated voltage

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?: The main function of the transformer is to change the voltage, and to solve the problem of voltage magnitude (amplitude, RMS)The main function of frequency converter is to change frequency and solve the problem of voltage and frequency.The main application of frequency converter to motor is to adjust the speed of motor by adjusting frequency. Because the speed of the motor is related to the frequency of the power supply. Can play a role in energy saving.

Q: Can 220V use frequency converter to drive three-phase motor with 380V?: The use of motor, if the star is connected to the corner of the connection can be, and if it is angle, then there is no way, and then the power of the motor will be reduced by about 4/10.

Q: What does "frequency" in household appliances mean?: The new inverter refrigerator not only the reduction of power consumption, realize mute, and the use of high-speed operation can achieve substantial rapid freezing; in the washing machine, used frequency variable speed control, improve washing performance, washing machine popular in addition to saving energy and silent, still ensure soft clothing washing and other aspects of the introduction of control new content;

Q: Frequency converter OC alarm, what's the matter?: And some did not inform you of the inverter fault category, when the OC boot failure, will cause greater danger, then simply caused by surface phenomenon similar to program crashes, such as the P9/G9 series machine when the machine detects INVT, module failure, operationThe H00 character appears on the panel, and all key actions are rejected. Unknown insider will think: program crash, CPU motherboard is a problem.
