Q:If it is 8-pole variable frequency motor, enter the motor nameplate parameters in the inverter input for the 4 pole can?
If the control accuracy is not high, then you can use the ordinary control. Since the choice of the inverter, it is best based on the motor nameplate to set parameters to ensure the stability of the motor running
Q:East yuan 7200GS inverter start 11KW 4-pole motor and 2-pole motor need to modify what parameters?
11KW 4-pole motor and 2-pole motor is the difference between the motor coil winding is not the same, the appearance of the 2-pole motor to be slightly larger, the speed of 4 pole speed is 1450 r / min, 2 pole is 970 r / min
Q:How do I select a drive? Which brand is better
  8, drive explosion-proof motor, the inverter is not explosion-proof structure, the inverter should be set in a dangerous place outside.     9, the use of inverter drive gear motor, the use of the gear by the part of the lubrication part of the lubrication control. When lubricating oil is lubricated, there is no limit in the low speed range. If there is a high speed range above the rated speed, there is a risk that the lubricating oil may be used. Therefore, do not exceed the maximum speed allowable value.     10, the inverter drive winding rotor asynchronous motor, most of the use of existing motor. Winding motor and ordinary squirrel-cage motor compared to the winding motor winding impedance is small. Therefore, it is prone to overcurrent trip due to ripple current, so a frequency converter larger than the normal capacity should be selected. General winding motor for flywheel torque more occasions, in the set acceleration and deceleration time should pay more attention.
Q:Three sets of batteries (540V) DC power supply U / f inverter.
This is the reason for the battery characteristics, your group of easy to burn the battery discharge characteristics of the curve should not be partial to engage, so easy to burn. Ultimately it is your group of battery quality is relatively poor!
Q:What is the output voltage of the laptop power adapter?
Generally have 19V of the common friends, I was 19V
Q:Notebook plug in the power adapter lights, but can not open the machine
Put the board under the re-installed, try and then boot. Asked: This is the case of removal, with the battery can boot answer: Then put the battery on the computer, and then use the power splitter to see if you can. If not I do not know, is the computer question to ask: This can be
Q:Motor 2 pole and 4 pole in the inverter with what set to show
Motor parameters, there must be a parameter "motor pole" of the bar.
Q:The laptop's power adapter can be used on a desktop computer
First of all, the desktop is the kind of power, is ups uninterruptible power supply. But relatively large, not directly inside the chassis. In addition, the storage capacity is limited.
Q:The Schneider inverter reports the nlp command
1, the inverter control circuit with an external 24V power supply, the main circuit did not power 2, PO and PA between the short film can not cause this failure.
Q:380V 2 pole motor can use the inverter?
Of course, the stator winding can be connected with concentric While enameled wire to be better, preferably 180 degrees or 155, and even dedicated enameled wire
