Q:Inverter signal line analog 4-20mA connection positive and negative can be reversed?
Theoretically reverse seems to be possible, but the operation will be normal, you can do experiments to try what is the result. Various manufacturers of the inverter may be the treatment of this problem will be different.
Q:Inverter ACS355 If the speed is outside the allowable range, how to set the limit value
1. Set 2002 MAXIMUM SPEED Defines the maximum permissible speed.
Q:Who knows how the inverter is calculated?
The synchronous speed of the two-pole motor is 3000 rpm,
Q:What is the number of parameters of the motor frequency of the Siemens inverter?
It is best to provide the model of the inverter Oh!
Q:My laptop can not use the power adapter, and can only use the battery, how is it ah,
1, laptop power adapter can not be used, first check the power outlet, plug, cable has no virtual state, if you can tell the normal equipment damage. Should be repaired. 2, the laptop battery must be charged through the power adapter or directly for the computer power, the power adapter is not missing, if you have experience can turn on the power adapter to see if the fuse is broken, try to update the fuse can be restored. If the integrated circuit is damaged, only updated.
Q:Laptop power adapter leakage
In fact, the adapter does not matter fake real goods, brand machine adapter are also purchased. According to my point of view, or I choose the words: casually buy one can, dozens of dollars on the line. In fact, the adapter is also worth tens of dollars, selling a few hundred dollars are also almost the same thing. Adapter is a small switching power supply, 100W or so, the value of that price.
Q:What is the difference between AC and DC frequency converters?
L inverter air conditioner refrigeration system components: inverter air conditioner by the compressor, evaporator, condenser, electromagnetic four-way valve, electronic expansion valve, defrost valve, double capillary and other components (see Figure II), work, air conditioner Room needs, automatic control of the inverter output frequency higher AC, the motor speed to speed up, the compressor cooling capacity increased to achieve the purpose of rapid cooling or heating, on the contrary, when the room cooling or heating less, Compressor to normal speed or lower speed operation, therefore, inverter air conditioner has a continuous cooling capacity adjustment, making the room temperature fluctuations smaller. In the process of compressor operation, the microcomputer system controls the inverter compressor at the same time, controls the opening degree of the electronic expansion valve, maintains the proper refrigerant flow, and directly changes the flow of the refrigerant in the evaporator to change its state, the compressor The speed corresponds to the opening degree of the expansion valve, and the displacement of the compressor corresponds to the supply amount of the expansion valve, so that the degree of superheat is not so large that the capacity of the evaporator is maximized, so that the refrigeration system The most efficient control.
Q:Is the laptop power adapter hot?
Third, the power of the nominal voltage than my books the battery voltage is much higher, not an accident, right? First of all, to know is that the power supply to the books and the battery power supply to the notebook is different. Battery-powered, the battery output is pure DC, very clean, the battery voltage is neither possible nor need to design a high, lithium battery chemical properties determine a cell output voltage can only be about 3.6V, so Many batteries are used in three cascade way, 10.8V also became a very popular battery voltage. Some batteries are slightly larger than the integer value of 3.6V, such as 3.7V or 11.2V, etc., in fact, to protect the battery. Power supply, the situation is more complex, first of all need to add voltage to further regulation filter to ensure that the power performance is not very good in the case of stable work, the voltage regulator after the two parts of the city, all the way to the work of the power supply , The other way to the battery charge to the part of the power supply to the battery when the same power supply, and the part of the battery charge through the battery charge control circuit can be added to the battery, the control circuit can be very complex, so the power The voltage must be greater than the cell voltage to have sufficient capacity to supply the charge control circuit to the units. Finally the voltage actually added to the cell will never be the nominal voltage of your power supply. Rest assured.
Q:How does the variable frequency motor output torque at very low frequencies?
50hz the following frequency, u constant, current and frequency is proportional to the frequency down the output current is also down, and torque and current is proportional to the natural torque is small
Q:How can a variable speed multi - speed three - phase asynchronous motor be controlled by a frequency converter?
Yes, but it is not necessary, if it is old motor that is another matter, tell you that you can use, but can not be in the frequency conversion process for the pole, this will cause the inverter protection or failure
