Q:What are the precautions for frequency converter wiring installation?
1, between the power supply and inverter, access to low-voltage circuit breaker and contactor, protection of frequency converter and easy installation and maintenance;2, frequency converter and motor are generally not allowed to access contactor;3, frequency converter generally does not need to meet the thermal relay;4, the output side of the inverter is not allowed to connect capacitors and capacitive single-phase motors.5, the surrounding pay attention to ventilation, dust-proof6, the power input line has sufficient area, the screws tighten as far as possible, but do not slip, you can refer to the specifications torque.7, connect the motor cable as short as possible, there are computer occasions, as far as possible shielded cable8, the control signal line should not parallel to the power line. If parallel must be used, the shielding line and one end of the earth will be used.9, use 485 or 232 communication to wear a magnetic ring, and use twisted pair.
Q:What is the TTK converter produced?
Mainly engaged in TTK brand inverter products R & D, manufacturing, SMT surface mount OEM processing, and agents of well-known brands at home and abroad, frequency converters and electronic components. The agent of many brands, manufacturers become the primary agent, after ten years of unremitting efforts, has formed the electronic components supply system, to meet the basic needs of all customers required inverter suction electronic components. Due to the rapid delivery, excellent reputation, has a large number of customers in East China. Now the Shanghai Volkswagen Schneider, L.D., and many domestic large enterprises supporting inverter and electronic components products supply, for many years by the number of units as the best supplier.
Q:I would like to ask, the inverter in use in the grid is very high?
Now the domestic and foreign status of power grid is different from that of Europe and the United States Department of conversion products to the domestic needs change, in fact, if you choose, you can choose domestic brands inverter, after all, or your own brand more familiar with the situation! Our factory in Chongqing, is used in conjunction with Kang high voltage frequency conversion, suitable for input voltage range comparison, but also very suitable for domestic power grid conditions.
Q:What does a frequency converter do?
Frequency converter1. What is a frequency converter?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.2, what is the difference 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.
Q:The frequency converter is in use suddenly the speed reduces, then the debugging is out of control, how to do?
Excessive voltage generation and regenerative braking, the so-called inverter over-voltage, refers to a variety of reasons caused by inverter voltage exceeds the rated voltage, concentrated in the DC bus frequency converter DC voltage. In normal operation, the DC part voltage of converter is the average value after three-phase full wave rectification.
Q:What does "EPCU" mean in a frequency converter?
But look at your inverter has also been used for some time, if not before, and now appear, it is estimated that the hardware is broken, and manufacturers communicate maintenance!
Q:What are the basis of the frequency converter to choose?
According to the applied industry.The application of inverter industry RGB field is widely used, the main products are: SAJ-S simple ultra small, SAJ-M mini, SAJ-G universal, SAJ-F type, SAJ-P type wind pump, SAJ-Y injection molding machine type, SAJ-Z type, heavy machine industry, naked personalized products, high performance vector inverter S350.
Q:What are the parameters of the frequency converter? Thank you
Some are called bias frequency or frequency offset settings. Its purpose is that when the frequency of external analog signals (voltage or current) to set, you can use this function to adjust the frequency setting signal, minimum output frequency, as shown in figure 1. Some of the inverter when the frequency setting signal is 0%, the error values in the range of 0 ~ Fmax, some converter (such as electricity forhomes Sanken) can also bias polarity settings. For example, in debugging, when the frequency setting signal is 0%, the output frequency of the inverter is not 0Hz, and xHz, then the bias frequency is set to negative xHz, so that the output frequency of the inverter is 0HzI
Q:What is the working principle of elevator frequency converter?
The basic principle of VVVF elevatorAccording to the theory of motor, the speed formula of AC motor is:N=60f (1-s) /pUpper type: F is the stator frequency, and P is the pole count;S is slip; n is speed.
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
