Common problems and solutions for servo motors

 1. Controller and motor matching problems

1. Mismatch of motor types
Mismatch of motor types is a common problem that causes servo motors to fail to operate normally. When purchasing a servo motor, you need to select the appropriate motor type according to actual needs. For example, a low-speed high-torque motor is suitable for occasions that require high torque output, and a high-speed motor is suitable for occasions that require high-speed response.
2. Controller configuration problems
Another common problem with controller and motor matching is improper settings. Incorrect controller parameter settings or mismatch with the motor model can also cause the servo motor to fail to operate normally. The solution is to read the controller manual carefully and set the controller parameters correctly.

2. Problems during interference and debugging
1. Power supply interference
Power supply interference is an important cause of servo motor problems. Excessive power supply noise can cause the servo motor controller to fail to operate normally, resulting in unstable motion and increased errors. The solution is to select a suitable power supply or use a filter according to quality requirements.
2. Mechanical problems
Mechanical problems are also one of the causes of servo motor problems. For example, failure, wear or damage of mechanical components can cause the servo motor to fail to operate normally. The solution is to maintain the mechanical components, replace and adjust them in time.
3. Debugging parameter setting problems
During the servo motor debugging process, it is easy to have improper parameter settings, such as parameter settings in proportional gain, speed limit, etc., which may affect the normal operation of the servo motor. The solution is to carefully read the controller manual according to the specific situation and check whether the parameter settings are reasonable.

3. Servo motor debugging precautions
1. Electrical debugging before mechanical debugging
Before debugging the mechanical parts, perform electrical debugging first to ensure the normal operation of the electrical part.
2. Debugging must be carried out strictly in accordance with the requirements
During the servo motor debugging process, it must be debugged strictly in accordance with the requirements, including debugging of speed, acceleration, position control, etc.
3. Pay attention to the output method
During the servo motor debugging process, you need to pay attention to the output method. Generally speaking, there are several ways for motor output, such as position control output, speed control output, and torque control output.
