Screw air compressor inverter failure is a common mechanical failure, troubleshooting the fault requires professional knowledge and experience. Here are some common exclusions:
1. Check the power supply: First, ensure that the inverter has been connected to the correct power supply, and the voltage and current are within the specified range.
2. Check the circuit board: Check whether the circuit board of the inverter is damp or other physical damage. If there is a problem, the board needs to be replaced.
3. Check the motor: Check whether the motor has abnormal sound or high temperature. If there is a problem, the motor needs to be replaced.
4. Check the sensor: Check whether the sensor is damaged or configured incorrectly. If there is a problem, the sensor needs to be replaced.
5. Check the controller: Check whether the controller is faulty or the parameter Settings are incorrect. If no, replace the controller or reset the parameters.
6. Shutdown maintenance: If the above steps can not solve the problem, need to stop for maintenance. Before maintenance, it is necessary to disconnect the connection between the frequency converter and the motor, and ensure that the frequency converter is completely stopped.
It should be noted that inverter troubleshooting requires professional knowledge and experience, so it is recommended to seek the help of a professional. Safety codes and procedures must be followed before any repairs are carried out.
