Reasons and solutions for stopping the motor after starting the frequency converter for a while (stop when running)

introduction

In industrial production, frequency converter is a common electrical equipment used to control the speed and operating status of motors. However, sometimes we may encounter a problem where the frequency converter stops running after starting the motor for a while, which can cause difficulties in the production process. This article will explore the possible causes of this problem and provide corresponding solutions.

1. Overload, overcurrent, short circuit and other issues

After the frequency converter starts the motor, if the motor stops running for a while, it is likely due to overload protection action caused by excessive motor load, or problems such as overcurrent and short circuit during motor operation. At this point, we need to check if the motor has any issues such as overload, overcurrent, short circuit, etc. If necessary, consider replacing the motor or conducting motor maintenance.

2. Incorrect parameter settings

The frequency converter starting the motor may stop after a while due to incorrect parameter settings. We need to carefully check whether the parameter settings of the frequency converter are in line with the actual situation. For example, whether parameters such as frequency, voltage, and current are set correctly. If any parameter settings are found to be incorrect, adjust them promptly.

3. Fault in the frequency converter itself

If the above two reasons are ruled out, it may be a malfunction of the frequency converter itself. We need to conduct maintenance on the frequency converter and check if there are any internal faults. For example, checking whether the IGBT module is damaged and whether the power board is working properly. If a serious fault is found in the frequency converter, it may be necessary to consider replacing the frequency converter.

conclusion

The problem of the frequency converter stopping after starting the motor for a while may be caused by various reasons, including overload, overcurrent, short circuit, incorrect parameter settings, and faults in the frequency converter itself. We should conduct investigations based on specific situations and adopt corresponding solutions. Timely resolution of this issue can ensure the normal operation of the production process and improve production efficiency.
