The use of advanced filtering technology, reasonable software algorithms, ...

Undervoltage is also a problem that we often encounter in application. Mainly because the voltage of the main circuit is too low (220V series is lower than 200V, 380V series is lower than 400V), the main reason: a certain way of the rectifier bridge is damaged or there is abnormal operation in the three ways of the thyristor, which may lead to the appearance of undervoltage problems, ...

Special inverter suppliers remind you that in daily industrial production, there are inverters that do not require rectifier units, which are the so-called alternating current inverters. However, the vast majority of the market is AC-DC-AC frequency converter, which also contains a rectifier unit, which is a certain level of technology and market competition.

1. When selecting the inverter, select the inverter with the appropriate control method according to the load characteristics In addition to the inverter manufacturing process, it is also important to choose which control method of the inverter. The control method of the inverter is mainly divided into two types: open-loop control and closed-loop control. In the meantime, the open-loop control method ...

In ancient times, there were ten major tortures, which made people unable to survive and die, and experienced the purgatory of the world; Today, there are ten "tortures" of inverters, and the same can make your inverters suffer. Let's follow the editor to find out which of the top ten "tortures" will make your inverter "worse than dead"! ...

The fulfillment device commonly used in the industrial field of Reynolds inverter has good speed regulation performance and simple and convenient operation method. Therefore, it is widely used in the automation system. Typical wiring method for the main circuit of a Reynolds frequency converter ...

1. Overpressure leads to brake pipe breakdown. The so-called overvoltage of the inverter refers to the fact that the inverter voltage composed of various reasons exceeds the additional voltage, which is reflected in the DC voltage of the inverter DC bus. Overvoltage alarm generally appears when the machine is shut down, and its main ...

I often see many beginners tossing on the resistor when overhauling the circuit, and it is dismantling and welding, in fact, it is repaired a lot, as long as you understand the damage characteristics of the resistor, you don't have to bother. Resistors are the most numerous in electrical equipment ...

Causes of inverter failure: 1. The grid voltage is too low 2. The rated current of the motor is set incorrectly 3. The motor stall or load abrupt change is too large 4. Large horse-drawn trolley Inverter solutions: 1 ...

There are many setting parameters of the inverter, and each parameter has a certain range of choice, and the inverter can not work normally due to the improper setting of a single parameter in use, therefore, the relevant parameters must be set correctly. ...

1. Test rectifier circuit: To the P end and N end of the DC power supply inside the inverter, adjust the multimeter to the resistance X10 gear, the red watch rod is connected to P, and the black watch rod is separated from R, S, T, and there are tens of ohms of resistance in normal times, and it is basically balanced. Instead, connect the black watch rod to the P end, and the red watch stick will be ...

Motor soft starter is the primary selection of power electronics skills and microprocessing skills and modern control theory and design and production of advanced level of new engine equipment, motor soft starter mainly has anti-interference function, high reliability, multiple protection functions and other characteristics, according to these characteristics of electric ...

When the high-power motor starts, the current is large, which will cause the grid voltage to be seriously shaken, in order to deal with this problem, the general requirements for speed regulation are not high, and the soft engine can be used to reduce the voltage and start. However, the drop in the starting current when the step-down is started will also make the starting torque drop significantly.

Misunderstanding: connect electromagnetic switches and electromagnetic contactors in the output circuit of the inverter In actual use, some occasions require the use of contactors for frequency converter switching: such as when the frequency conversion is faulty, switch to the power frequency operation, or when the one-to-two method is adopted, a motor is faulty, and the variable frequency is used.

Dynamic "fast response" DC motors are rectified constrained and excessively high di/dt is not allowed. The asynchronous motor is only constrained by the capacity of the inverter, and the multiple of the forced current can be very high, so the speed echoes quickly, generally reaching the millisecond level, which has surpassed the DC motor in terms of speed. At low frequencies ...

F09 second acceleration time 0.10 - 999.9sec; 5.0sec； △** The acceleration and deceleration parameters and the second acceleration and deceleration parameters are switched by terminal X3 (see F55); F10 second deceleration time 0.10 - 999.9sec; 5.0sec； △**Acceleration and deceleration parameters and the second acceleration and deceleration parameters are switched ...

In order to ensure the safe, efficient and reliable operation of the inverter, the following keys should be grasped when using the inverter: 1) It is necessary for the grounding terminal of the inverter to be firmly grounded, so as to effectively press the radio frequency disturbance and enhance the reliability of the system: the frequency conversion speed regulation system is best to use independent grounding, grounding resistance...

1. Clarification of the function of the control panel 1. FUN button; Press the FUN button to enter the settings menu F00; 2. Press and hold the up or down button to scroll to the code you need to set; 3. At this moment, press the FUN button to confirm, and adjust the entry parameters to the required value; 4. After the adjustment is completed, ...

The development of the inverter has experienced a slow and gradual process, and the inverter at the beginning of the first century did not choose this kind of AC-DC: communication to DC and then to communication, but direct AC, no central DC link. This kind of inverter is called alternating frequency converter, and now this kind of inverter is in the ultra-high power ...

1. The switching signal of PLC controls the inverter The PLC can control the start, stop and reset of the inverter through the program; It can also control different combinations of high-speed, medium-speed and low-speed terminals of the inverter to achieve multi-stage speed operation. However, because it is controlled by switching ...
