5SHY3545L0009 系統(tǒng)發(fā)生機(jī)電共振

The system has an electromechanical resonance, which can be judged from the sound of the motor running. The method of setting the frequency jump value can avoid the resonance point. Generally, the inverter can set three jump points. When the V/f controlled frequency converter drives the asynchronous motor, in some frequency segments, the current and speed of the motor will oscillate, and the system can not run in serious cases, and even the over-current protection in the acceleration process makes the motor cannot start normally, which is more serious when the motor is light load or the moment of inertia is small. Common frequency converters are equipped with frequency jump function, users can set the jump point and jump width on the V/f curve according to the frequency point of oscillation in the system. When the motor accelerates, these frequency segments can be automatically skipped to ensure the normal operation of the system.
The torque output capacity of the motor is not enough, the factory parameter Settings of different brands of inverters are different, under the same conditions, the load capacity is different, and the load capacity of the motor may be different due to the different control methods of the inverter. Or due to the different output efficiency of the system, the carrying capacity will be different. In this case, the value of the torque lift can be increased. If not, the manual torque lifting function can be used, do not set too large, the temperature rise of the motor will increase at this time. If it is still not possible, a new control method should be used, such as Hitachi inverter using a constant V/f ratio method, when the start fails to meet the requirements, the speed sensorless space vector control method is used, which has a greater torque output capacity. For fan and pump loads, the curve value of torque reduction should be reduced.
