1. Check and Adjust the Load
Overloading of the inverter is often related to excessive load. If an overload is suspected to be caused by heavy load, check the actual load condition of the screw air compressor to avoid prolonged overloading. If necessary, consider adding backup equipment to distribute the load.
2. Adjust the Inverter Parameters
The parameter settings of the inverter significantly affect its operational stability. Verify if the acceleration time, deceleration time, and torque boost settings are appropriate. If acceleration is too fast, the motor will experience a sudden surge in current. Conversely, excessive deceleration may cause regenerative energy surges. Adjust the parameters based on the actual operating conditions of the screw air compressor to ensure smooth motor start-up, shutdown, and operation, preventing unnecessary current overload.
3. Strengthen the Maintenance of the Cooling System
Inverters generate a significant amount of heat during operation. If the cooling system malfunctions or the cooling conditions are poor, the internal temperature of the inverter will rise, leading to overload protection activation. Therefore, it is essential to regularly clean the inverter’s interior of dust and debris, ensure proper ventilation, and confirm that the cooling fan is functioning properly.
