Q: What are the modes of operation of a frequency converter?: On board test run 11 manual operation of the frequency converter panel stop key, observe the motor running process and the frequency converter display window, to see if there is abnormal phenomenon. 21 if the P is started and the over-current protection is stopped in the motor, the acceleration P deceleration time should be reset. The acceleration of the motor during acceleration and deceleration depends on the acceleration torque, while the frequency change rate of the inverter during the start and braking is set by the user. If the inertia of motor or motor load change, speed or deceleration rate according to frequency change preset when possible acceleration torque is not enough, resulting in motor stall, motor speed and the inverter output frequency coordination, thus causing overcurrent or overvoltage.

Q: What does a frequency converter do?: 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?: Specific answer to your question: 1, high voltage inverter: This is based on the input voltage level terms. Generally speaking, 10KV is more than 6KV voltage high voltage frequency converter, 1140V, 3300V in general is medium (some people also called it the high voltage level of 380V, 660V), 480V, commonly called the low-voltage inverter; 2, pump inverter: This is according to the type of application in terms of. Fan pump inverter mainly refers to the frequency converter used to drag fans, pump load, the main feature is light load, simple application.

Q: 1, the frequency converter to the motor cable should be shielded cable? 2, whether there are specifications?: Or, ask another question: "under what circumstances can the frequency converter go to the cable of the frequency conversion motor without using shielded cable?" Is there a "no need to use shielded cable" basis?

Q: What are the differences between the two quadrant and the four quadrant of the inverter?: For a motor alone, the so-called four quadrant refers to its operating mechanical characteristics curve, on the mathematical axis of the four quadrants can run. The first quadrant is in the positive electric state, the second quadrant feedback braking state, the third quadrant reversing electric state, and the fourth quadrant reverse braking state. A frequency converter that makes the motor work in the four quadrant is called the four quadrant converter.

Q: How to deal with the fault Yaskawa inverter GF: Inverter display "GF" fault information for ground fault (i.e. the output current exceeds the rated current of the inverter 50%), a power module is reported for G5 damage, may also be a driving circuit, running the report "GF" (the external load is a good case), G5 is PC929 damage. With current detection circuit,

Q: What is the difference between SIEMENS inverter and built-in filter?: The filter is used for electromagnetic interference protection. Not only for the protection of electrical equipment, but also for the use of environmental protection. Inverter application environment is very extensive. Industry, light industry, commerce, civil, etc.. So the level of electromagnetic protection is also different.By the way。 If you disconnect the converter. See a coil on a board. That's the built-in filter. If you don't have it, you don't have that coil.

Q: What does "frequency" in household appliances mean?: The technology of frequency conversion technology called frequency conversion technology and home appliances in 1970s AC control by changing the frequency of the AC current, household appliances gradually began to appear frequency, electromagnetic cooking device, inverter lighting apparatus, inverter air conditioner, microwave frequency, variable frequency refrigerator, IH (induction heating cooker), inverter washing machine etc.. In the latter half of 1990s, household appliances relied on frequency conversion technology, mainly aiming at high function and power saving. For example, with high speed, high output, good control performance, small light weight, large capacity, high comfort, long life, safe and reliable, mute, power saving and so on.

Q: What is the TTK converter produced?: TTK inverter is made in Zhejiang.TTK series general frequency converter is a high quality, multi-function and low-noise converter developed and produced independently by our own. Its rich functions fully meet the various needs;

Q: There is much dust and moisture in my workshop. Many brands are not durable.: ABB inverter is of high quality, but it requires a lot of environment, such as dust and humidity in your workshop. It is too bad for ABB inverters. You can try to use the seal of inverter, it is designed according to the use environment of inverter in various industries, mainly considering China's current converter relatively harsh environment (water vapor, dust, oil, metal powder, corrosive gas), in CNC lathe, grinding machine chemical plant, reaction kettle, blender, textile machinery, printing and dyeing equipment, water pump, industrial washing machine, dehydration machine where the effect is very good.
