We will cherish every opportunity to cooperate with you and look forward to your consultation and cooperation, let us work together to create a better future! The company is the manufacturer, such as the need Fairchild inverter series, machine type, fan and pump type, frequency machine, water type, stop delay, track-type and stone cutters and other models, you can contact me direct the Secretary customization, please consult the discussion! Fairchild Shenzhen Technology Co., Ltd. welcome your calls, enthusiasm for your service! Micro-channel enterprise public account: Fairchild Drive following is a promotional article to check the motor side is balanced if the three-phase voltage three-phase voltage imbalance motor side, you should then check the inverter output phase voltage is balanced, if not balanced , the problem is inside the drive, check the drive inverter module and its drive circuit. If the voltage output of the inverter balance, the questions on the line from the inverter to the motor between the terminals should check whether all the screws are tightened. If you have contacts or other electrical appliances between the drive and the motor, you should also check whether the electrical terminals are tight, and the contact is in good condition and other contacts. If the motor side of the three-phase voltage balance, you should understand when the trip Frequency: as low frequency, but not with the vector control (with or without vector control), the first lower U / F ratio; able to drive a load such as reducing post , then the original preset U / F ratio of the peak value is too high, the magnetizing current is too large, the current can be reduced by reducing the ratio of U / F; and if lower with fixed load, and you should consider increasing the inverter capacity; if the drive has a vector control, vector control method should be used.
