Emerson MFC075B0M3 frequency converter power board

Selection of frequency converter power
The system efficiency is equal to the product of the efficiency of the frequency converter and the efficiency of the motor. Only when both are operating at high efficiency, can the system efficiency be higher. From an efficiency perspective, when selecting the power of a frequency converter, the following points should be noted:
1) When the power value of the frequency converter is equivalent to the power value of the motor, it is most suitable to facilitate the operation of the frequency converter at high efficiency values.
2) When the power rating of the frequency converter is different from that of the motor, the power of the frequency converter should be as close as possible to the power of the motor, but slightly greater than the power of the motor.
3) When the motor is frequently started, braked, or under heavy load starting and working frequently, a larger frequency converter can be selected to utilize the frequency converter for long-term and safe operation.
4) After testing, it has been found that the actual power of the motor is indeed surplus. It is recommended to choose a frequency converter with a power lower than the motor's power, but attention should be paid to whether the instantaneous peak current will cause overcurrent protection action.
5) When the power of the frequency converter and the motor are different, the setting of the energy-saving program must be adjusted accordingly to achieve a higher energy-saving effect
