Q: Application of ABB frequency converter: Why is the voltage of the inverter proportional to the current?Asynchronous motor is the torque between the current flowing through the motor flux and rotor as a result of the interaction, at rated frequency, but only if the voltage will reduce the frequency, then the magnetic flux on a large magnetic circuit saturation, the motor will be seriously burned. Therefore, the frequency and voltage should be changed proportionally, that is to say, to change the frequency, to control the output voltage of the converter at the same time, to keep the flux of the motor to be certain, and to avoid the occurrence of the weakening of the magnetic flux and the saturation of the magnetic flux. This control mode is mostly used in fans, pumps and energy saving inverters.

Q: High-voltage converterGeneral inverterPump frequency converterEngineering frequency converterCould you tell me some frequency converter according to the class?: According to the classification of link Transformation: (1) the AC-DC-AC converter is the first AC into DC rectifier through, and then transformed into the frequency DC voltage adjustable AC inverter, also known as indirect, is currently widely used general-purpose inverter. (2) can be divided into cycloconverter, is directly converted into AC voltage adjustable frequency AC, also known as direct inverter DC power supply according to the classification of properties: (1) the voltage type inverter voltage type inverter is characteristic of DC link energy storage device using a large capacitor load reactive power will be it is to buffer the DC voltage, DC power supply is relatively stable, smaller internal resistance and the equivalent voltage source, so that the voltage type inverter, are often used for load voltage changes in the larger situation. (2) current inverter current type inverter is characterized by large DC link inductance as a storage buffer of reactive power, which changes the current control, the voltage is close to sine wave, because the DC resistance is large, so that the current source converter (current). The characteristics of current source inverter (advantages) can restrain the load current is frequent and rapid changes.

Q: How does the frequency converter change the voltage and change the speed of the motor?: N = 60f/PN is the turn speed, F is the frequency, and P is the magnetic pole logarithm of the engineBy the formula: frequency and speed is proportional to, so the inverter can change the speed of the motor

Q: How does the frequency converter fit the brake unit and the brake resistor?!: To calculate how much energy consumption, can be converted into electric current, to select the brake unit. You can also choose the braking resistance (to consider resistance temperature characteristics to choose), then select the brake unit with matching (see manufacturer manual).

Q: I am in control of the equipment: the same mechanical movement, this needs a motor drive, a frequency converter drive. Now it's due to the mechanical location: buy two units of the same motor. Can you use a converter in parallel to drive it? Please point out! Thank you (frequency converter: the power of Schneider is equal to the sum of two motors): Can be controlled at the same time, but the power of the inverter is equal to the sum of the power of the two motors multiplied by 1.2 times before you can. And the inverter output can not add contactor. To ensure that the inverter is to control the start and stop of the two motors.

Q: What does 0L1 stand for?: The acceleration is generally overloaded during acceleration. Load inertia is too large, the inverter power is small, or the acceleration time is too short, and so on

Q: How do you understand the ramp up (descent) time of the inverter? Thank you!: That is, the frequency converter starts from the time it takes to set the upper limit. It can be said to be the acceleration time, which can be set in the parameters of the converter. Then, the deceleration time is just the opposite.

Q: How to maintain the frequency converter will not damage, or regular maintenance?: The correct use method and reasonable maintenance can extend the service life of the inverter to a certain extent. The common maintenance methods of the inverter are cleaning the air filter, cooling the air duct and the interior dust. Check whether the screws, bolts and plug are loose, the input and output reactor ground and interphase resistance is short circuit, the normal should be more than tens of megabytes of europe. The conductor and insulator are corrosion phenomenon, if in time to wipe clean with alcohol.

Q: There is much dust and moisture in my workshop. Many brands are not durable.: The quality is very good.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.

Q: I do mining equipment, recently I used ABB frequency converter to put into our equipment, but the problem of interference really gives me a headache! We have two pieces of equipment of SIEMENS S7-200 PLC, and is used in point to point protocol communication with each other, when the converter work PLC communication interference! There are monitoring equipment, converter work, there are a large number of snowflakes on the screen, simply do not see! Not even an internal phone! I've done well in grounding, but I still can't do it! Is there any master who can teach me a trick?: You can try using the following methods:Solution of interference caused by circuit coupling:The PLC and monitoring equipment are powered by isolated transformers.
