6 Frequently Asked Questions about “High frequency inverter overload”
What is a frequency inverter overload?
The motor can rotate, but the running current exceeds the rated value, which is called overload. The basic reflection of overload is that although the current exceeds the rated value, it does not exceed the rated value by a large margin, and generally does not form a large impulse current. What are the main causes of frequency inverter overload?
How to know if an inverter is overloaded?
The preset value of the electronic thermal protection function should be relaxed if there is still room for the inverter. If the temperature rise of the motor is too high, and the overload is normal overload, the motor is overloaded.
What causes a frequency inverter to tripping?
1.Wrong action. The fault occurred in the current detection part of the frequency inverter, and the detected current signal was too large, leading to tripping. 2.Heavy mechanical load. The main feature of heavy load is the heating of the motor, which can be found by reading the running current from the display screen. 3.
What is a two-level three-phase inverter?
The predominant two-level three-phase inverters apply Pulse Width Modulated (PWM) voltages to the motor wind-ings, which potentially lead to, e.g., bearing currents, High-Frequency (HF) harmonic losses, over-voltages be-tween the coils and Low-Frequency (LF) oscillations at the neutral point inside the motor.
How to check if a frequency inverter has a vector control function?
If the inverter has a vector control function, the vector control mode should be adopted. Check whether the motor is heated. If the temperature rise of the motor is not high, the electronic thermal protection function of the frequency inverter should be checked first.
How to reduce current in an inverter?
The current can be reduced by lowering the U/f ratio. If the reduction with a fixed load, you should consider increasing the capacity of the inverter. If the inverter has a vector control function, the vector control mode should be adopted. Check whether the motor is heated.
