Q:What is the motor series parameter setting of the inverter? If it is with the spindle,
Ordinary inverter standard drive is a 4-pole motor, the greater the number of poles of the motor, the greater the rated current, the motor pole number is the frequency converter when the self-learning automatically set, in the vector control must be self-learning
Q:What is the adapter?
USB adapter Buy a USB adapter: http://cew.earch14.com/usb-adapters Audio-Video Adapter: Also offers the following types of audio-video adapters: O DVI to HDMI audio video adapter O DVI to VGA audio video adapter O RCA adapter O SCART adapter O XLR adapter O audio adapter
Q:Is the laptop power adapter long-haul?
Oh, the power adapter is a transformer, we use the electricity is 220, after it will be converted into a suitable computer voltage, or notebook can not withstand 220V, so as long as the power inside the transformer will work, If you do not have a computer, it is best to unplug the plug on the power outlet, even if the computer has to pull out from the outlet, or will have an impact on the life of the adapter.
Q:Do you want to pay attention to the number of poles of the motor when selecting the inverter?
Inverter is generally selected by the power, do not consider the number of poles, but the inverter output current is controlled by the module, so you can choose in the selection as much as possible in accordance with the rated current to select the inverter. And left redundant party B overload and other phenomena.
Q:How to view the parameters of the notebook power adapter on your computer
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. Notebook power adapter using the correct method] 1. Try to avoid the use of outdoor or harsh environments to prevent the adapter is exposed or damp. 2. When you are not using the adapter, please unplug the power plug. Because, for a long time the power will let the adapter has been in working condition, will affect the end of life. 3. Although the adapter is a broadband operating voltage, marked from 100V-240V can be, but if the voltage is extremely unstable in the case of use, the same will cause damage to the power adapter.
Q:Short-term short-circuit converter DC link positive and negative will damage the inverter?
This short circuit may not necessarily line, the inverter fan has three, one is no speed line, two are pulse, three are switching signal (this is very little, I only encountered several),
Q:Huichuan frequency converter drag a 4-kilowatt four-pole motor to change the six pole can?
Change 6 will only be slower, the fan is no longer role. The frequency converter has a power parameter, as long as the motor is less than or equal to this power can be.
Q:First reduce the frequency of about one-third of the test, not the case, then appropriate adjustments!
In short, then connected to the bk-dk electrical appliances, is a resistor for the discharge effect
Q:What is the frequency converter used to do, why some motor with the inverter?
Therefore, the exchange frequency control has gradually replaced the traditional traditional slip speed, variable speed control, DC speed control system, more and more widely used in metallurgy, textile, printing and dyeing, smoke machine production lines and buildings, Water supply and other fields. The motor is equipped with the frequency converter.
Q:Can the laptop 1.3a power adapter be used on a 1.5a device?
Absolutely can not try 1.5a! If you want your laptop to go wrong, then use it!
