Q:Delta inverter reported CE4 reasons? Casually asked how many kinds of CE under a total
If the Delta C2000_M is the Modbus drive can not handle Not to the official website under the manual
Q:How does the laptop's power adapter open
Control Panel - System - Hardware - Device Manager - Network Adapter, right click, and the menu appears. If it is infinite, then first follow the above argument to see if it can be enabled.
Q:Lenovo laptop power adapter side of the feet which is positive
Very simple, look carefully on the power there is a symbol on the map (relatively small, carefully looking for all the regular power above the standard), as I shown below is the positive external, most of the power is like this , If the sign on the icon is anti, that is connected to the center of the black point is negative, that is negative inside the positive. This figure is also very intuitive.
Q:Who knows how the frequency converter works
Rectifier circuit The function of the rectifier circuit is to convert the AC power into a DC power supply. Rectifier circuit is generally a separate rectifier module.
Q:Will the 75KW4 pole motor can be used to increase the speed of the inverter?
can! The output frequency of the inverter is higher than 50HZ, the speed of the motor is higher than the rated speed. In a certain range, the higher the frequency of the inverter, the faster the motor speed.
Q:I have a 5.5 kilowatts of 4-pole motor, want to pass through the inverter, slow down to 130 per minute use, eliminating the need for speed,
wo recommendations, the first, the use of vector control of the inverter, you are expected to run the frequency of about 5Hz, this time, ordinary V / F inverter output torque may be small, not necessarily meet the requirements, of course, if it is High-end imported inverter, the problem should be small, with the domestic vector inverter, the frequency can also be full torque output;
Q:What is the difference between the collector and the emitter mode?
The emitter is very high, the base is mixed and the collector is the lowest
Q:Delta VFD-A frequency converter motor number of poles set
According to the actual needs of the motor To provide the required power supply voltage, and then to achieve the purpose of energy saving, speed control, in addition, the inverter there are many protection features, such as overcurrent, overvoltage, overload protection and so on. With the continuous improvement of industrial automation, frequency conversion The device has also been very widely used.
Q:I have a 11KW-4 pole inverter, now with the 4KW-4 pole motor, what impact?
The inverter burns should be. Your motor overload is relatively large,
Q:Laptop power adapter output voltage is not the same as the current? What's the effect?
I would like to elaborate on the basic principle of the large standard current power supply can replace the small standard current power supply. Some friends have misunderstood, that a large nominal current power will burn books, because the current big thing. In fact, how much current in the same voltage depends on the load, that is, the work of the books, when the books of high-load operation, the current larger, the books into the standby time, the current is smaller, in short, On the voltage divided by the equivalent resistance of the books. Large nominal current power supply has enough current margin, will not be replaced by a small standard current power supply after the overheating or output voltage is too low. On the contrary, with a small current power supply instead of high current power on the existence of the above risks. But some friends with 56w power supply instead of 72w with no problem, because the power adapter is usually designed to leave a certain margin, the load power should be less than the power supply,
