Q: Ordinary 4-pole motor Under the control of the inverter, the higher the speed, the higher the power or the slower the power: It is wrong; the higher the speed is not equal to the greater the power;

Q: Can the laptop power adapter be generic?: Not common. Different computer adapter interface is not the same, and the voltage, current is not the same. If just the same, you can use, the voltage can also be used.

Q: What is the laptop power adapter? Is it the battery?: Notebook power adapter, of course, is not referring to the laptop battery.

Q: Motor nameplate on the standard 2P, I set the number of motor pole in the inverter, is set 2 or 4 pole?: 1,2P refers to the number of motor poles, so it is certainly even 2, if the inverter is set to determine the number of motor poles, please write 2P value, if 2P = 4, please write 4 3, look at the nameplate on the motor rated speed for how much, you can confirm the number of motor poles. (N = 60f / p) P: pole pairs

Q: Does the teacher know the working principle of the inverter?: Very basic questions, the principle of fine you go online search, everywhere, I do not like to copy someone else, I simply tell you about: Voltage type inverter Three-phase alternating current to the rectifier module, converted into DC, filter stored in the electrolytic capacitor, IGBT + and - from the electrolytic capacitor to take energy, by the DSP (or other controller) output PWM pulse control IGBT turn on and off, So the output AC, the AC and input AC waveform is very different, so that the inverter is also a source of interference. Current filter in the middle of the filter is the inductor non-capacitance, we are more commonly used on the market and the economic converter are mostly voltage-type inverter.

Q: Laptop power adapter (no power supply, but indicator light): With a multimeter to measure the power adapter output interface voltage, no voltage is the adapter problem; a voltage is a notebook problem, and then decide how to do it. The adapter interface is less likely to be bad, but it does not exclude motherboard interface or power control chip problems. The former 50 yuan can get, the latter need a few hundred dollars.

Q: Do you want to pay attention to the number of poles of the motor when selecting the inverter?: Such as Schneider: ATV21 for fans, ATV11 simple machine pump, ATV31 simple machine, ATV61 fan with pump, ATV71 high power machine, high torque performance

Q: There is no inverter comes with simple PLC programming function: Inverters are generally digital input, and analog input, a digital output, etc., can also be controlled by means of communication. Digital input can be used as a positive and negative and reset the alarm, the analog input can be given as a speed, and how to use the inverter to see the specific model. Take the Siemens inverter, MicroMaster420,567 terminal 3 digital input, 8 for the 24V, 9 for the 0V, you can usually open the point on the 8th 24V back to 567, as a digital input, you can also directly into the switching power supply Of the 24V, but the switch power supply 0V and 9 terminals connected to the potential, or the inverter may not be able to identify the outside world 24V. (DP communication, USS communication, etc.), with the terminal input on the P0700 = 1, the user can set the command source, the panel can be input, 2, P0701 to P0703 corresponding to the three digital functions: parameters set to 1 forward, 2 for the reverse ... ... a lot of features and control methods, see the corresponding product manual like

Q: Do not the laptop directly connected to the power adapter?: 4, but you can use the external 14 ~ 20V battery, connected to the matching power plug for the notebook power supply, the effect and the use of the same power adapter.
