1. Circuit failure

The circuit of the servo motor control system is composed of multiple components. The working problem of any component may cause the servo motor to malfunction. For example: controller internal fault, motor drive board fault, etc.

2. Sensor failure

The motion status of the servo motor needs to be detected and fed back through the sensor. When the sensor is faulty, it will cause the servo motor motion to be distorted. For example, the error of the feedback signal is too large, the sensor is aging, the contact is poor, etc.

3. Mechanical failure

The servo motor and the mechanical device are matched, and mechanical problems will seriously affect the work of the servo motor. For example, the driving device is aging, mechanical parts are loose, etc.

In view of the above possible reasons, the problem of the servo motor rotating forward and reverse can be solved by troubleshooting the specific reasons and performing corresponding repairs and replacements.

Conclusion

Through the above analysis of the servo motor rotating forward and reverse, we can see that this problem is caused by a variety of possible reasons. Therefore, when operating the servo motor, you must pay attention to safety and usage methods to avoid problems.
