Q: 3.7KW inverter with 2.2KW 6-pole motor running to see the inverter shows the current is more than 4A, with the amount of clamp to 2.8A: Two questions: 1, the inverter output waveform is not a standard sine wave, with the ordinary calorimeter measured value is completely not allowed. The output current of the inverter is the same.

Q: Laptop power adapter bad what is the phenomenon?: Either the power is bad or the machine on the power supply module is bad to repair service

Q: Octopus AC Servo motor can be driven with ordinary inverter?: If it is asynchronous motor, then take the power, voltage matching ordinary inverter drive no problem, you only need to enter the appropriate parameters, such as current, power size and other parameters, and then off-line parameters from the adjustment (if the vector control run), you can run

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,

Q: The Schneider inverter reports the nlp command: Current transformers are also possible, or power supplies

Q: Fuji inverter motor set the number of poles will not have any effect?: The number of motor poles corresponds to the speed of the motor, the number of poles is not set when the speed of the control error, in the high speed requirements of the transmission is not allowed.

Q: 11kw 6-pole motor can be used to adjust the inverter to 1800RPM?: Frequency converter in the 5-50Hz is constant torque frequency, 50-100Hz is constant power frequency, to see what you want to get the effect

Q: Whether the inverter can control the start and stop of the horizontal monopole centrifugal pump: Hi, the inverter control is no problem. You need to select the inverter by the load characteristics of the centrifugal pump, consider: Centrifugal pump rated working current, overload capacity, parking whether there is emergency stop request. I used the inverter to control the horizontal centrifuge some time ago.

Q: Laptop power adapter is used to do what: The laptop's power adapter is a device that converts 220V AC power from a power supply unit to a low-voltage direct current device for powering a laptop. Power adapter output low-voltage direct current into the computer, but also through the computer motherboard power circuit to further deal with, resulting in 1.8V, 3.3V, 5V and other sets of voltage for memory, CPU and other components to run; another power adapter to provide the power can also be related Charge control circuit to charge the battery for the laptop.

Q: Three motors, if coupled with the governor speed, is it necessary to add the inverter?: ?Second, the variable speed: change the way the stator winding wiring to change the cage motor stator pole pairs to speed.
