Q: Surface grinder can add frequency converter, what are the advantages and disadvantages?: Three frequency converter successfully used in NC machine toolsIn recent years, with the rapid development of the economy, the machine tool industry has also made rapid progress: it is reflected in the wide application of new technology and the obvious improvement of enterprise benefit. At present, the mainstream of consumption in machine tool industry is CNC machine tools. From the domestic and international market demand for CNC machine tools, after the NC machine tool market has the following characteristics: first, the economic CNC machine tools is the mainstream of the future products. Two, using new technology to reduce costs and improve product stability is the key to enterprise survival. Below we in the machine tool drive aspect uses the frequency control speed to say SAJ frequency changer in this profession application situation:

Q: Why does the frequency converter cause interference?: Method for solving interference caused by frequency converter:Adopt software anti-interference measures: specifically, the carrier frequency of the inverter is lowered through the man-machine interface of the inverter, and the value is reduced to an appropriate range. If this approach does not work, then only the following hardware anti-interference measures can be taken.Carry out the correct grounding: through the field investigation, we can see that the site of the ground is not ideal. The correct grounding can not only effectively suppress external interference, but also reduce the interference of the equipment itself to the outside. It is the most effective measure to solve the interference of frequency converter. Specifically, do the following two points:

Q: High-voltage converterGeneral inverterPump frequency converterEngineering frequency converterCould you tell me some frequency converter according to the class?: Frequency converter classification method can have many kinds, according to the technical characteristics of the points, according to the voltage level to be divided, and also according to the application characteristics of the points. It's hard to make a brief statement. The four types of frequency converters you list are based on different classification methods. The above is according to the technical classification to tell you, more complex, I will not say more.

Q: How does the frequency converter fit the brake unit and the brake resistor?!: Using these kinetic energy, the brakes can be used, like the brakes of a car, by turning kinetic energy into heat energy to consume the kinetic energy of the motor shaftAnother way is to say that you use a braking unit with a set of braking resistors. The principle is to change kinetic energy into heat, and use electrical resistance to heat up the kinetic energy of the motor

Q: What does the base frequency 60Hz represent in the inverter?: How to set the frequency converter: inverter frequency parameter should be set to the rated frequency of the motor is set up, and not according to the load characteristic set, even if the selection is not suitable for motor load characteristics or parameters must also try to follow the motor, easy over-current or overload.

Q: Where is the frequency converter used?: The machinery manufacturing industry, including: elevator, automobile, textile, printing and packaging, paper making, hoisting machinery, food, tobacco, etc. the use of these pumps, inverter industry is mainly in electrical equipment, control and obtain the best product performance and output rate is the main purpose of energy saving is different from the 1 in

Q: How to deal with the fault Yaskawa inverter GF: See the Yaskawa inverter protection circuit structure, and the other is the same frequency. Over current OL1, OL2 and OL3 fault signals should be current transformers and subsequent current detection and processing circuits and CPUThe fault signals of GF (ground) and OC (load side short circuit) shall be fed directly to the protection circuit of the drive circuit board to feed the CPU. The difference is that at the initial stage of the start-up, the detection module is abnormal, i.e., a fault is reported.If the module is detected in operation, the OC fault is reported. These two kinds of signals, but also revealed such a message: the initial stage, it has not yet established the three-phase output voltage, the load is not running, the actual fault sources should be inverter driving circuit or the IGBT module itself caused by the abnormal, but does not rule out a ground fault load;In operation, there is a very large current, jump OC, the load side of the probability of failure is large, but also over current fault, rather than ground fault. The difference between GF and OC faults and what they mean is really reasonable.

Q: What's the role of an electric car, the part of a traditional car?: High performance control algorithm.The vector control algorithm (field oriented control) is a leap of AC speed regulation technology, it through the orientation of motor flux, realizes the decoupling control of AC motor, the amplitude and the space position of the motor flux vector in dynamic and steady state are controlled, so that the dynamic performance of AC motor speed control, steady state is comparable with the DC motor speed control system, even in some cases beyond the latter. Thus, this algorithm is applied in the field of electric vehicles, electric vehicles to meet with large torque at low speed, ensure that it has good acceleration performance and climbing ability; also meet the wide speed range, so that the electric vehicle has the performance of high speed driving on the road.

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: The input is AC 50Hz sine wave output frequency variable, but still want to be sinusoidal. But due to various reasons such as the efficiency and control it is not directly output sine wave. It is the original inverter with high frequency sine wave modulation is Fang Bo, will be on the radio. As the modulation principle this is also called the square wave carrier. Between hundreds to thousands of HZ. In the range of our hearing. When it can be produced by mechanical vibration equipment such as reactors will sound when conducting ]. This is the voice we heard.The frequency of electromagnetic waves is high, that is, the corresponding mechanical vibration can occur, and it is also the frequency that the human ear can not hear, so it can not be heard

Q: What is the main harmonic produced by a transducer? How about the degree?: From the structure point of view, the inverter can be divided into indirect frequency conversion and direct frequency conversion of two major categories. The indirect frequency conversion turns the power frequency current into DC through the rectifier, and then converts the DC to the controllable frequency AC through the converter. The direct frequency converter transforms the power frequency exchange into the controllable frequency exchange, without the intermediate direct current link. Each phase is a reversible circuit in which two thyristor rectifier devices are antiparallel. The two groups of positive and negative switches are switched by a certain period, and the alternating voltage is gained on the load. The amplitude of the U0 is decided by the control angle of each rectifier device, and the frequency is determined by the switching frequency of the two sets of rectifier devices, and the frequency of the U0 is determined by the switching frequency of each rectifier unit. At present, more or more inter frequency converter.
