Servo motor vibration may be caused by various reasons, such as unreasonable parameter settings, mechanical connection problems, load changes, etc. The adjustment method can start from checking and optimizing parameter settings, ensuring stable mechanical connections, and checking load conditions.

1、 Common causes of shaking:

1. Mechanical factors:

Unstable fixation: Check if the servo motor and load are firmly fixed. If they are loose, they need to be re fixed.

Belt or gear issues * *: Check if the belt is too loose or worn, and if the gears are damaged, as these issues can cause shaking.

Unbalanced load: If the load is uneven, it may cause the motor to shake. Ensure even distribution of load.

2. Electrical factors:

Power supply issue: Voltage fluctuations or noise from the power supply may affect the operation of the servo motor. Use a voltage regulator or filter to stabilize the power supply.

Improper controller parameter settings: Incorrect gain settings may cause jitter. Adjust PID parameters according to the manufacturer's guidance.

Encoder issue: Encoder failure or connection issues may also cause jitter. Check if the encoder is working properly.

3. Software factors:

Control algorithm issue: If a custom control algorithm is used, there may be design issues with the algorithm. Check and optimize the algorithm.

Command signal issue: Unstable or interfering command signals may also cause jitter. Ensure that the command signal is clean and stable.

4. Environmental factors:

Temperature impact: Temperature changes may affect the performance of the motor. Ensure stable working environment temperature.

Electromagnetic interference: Nearby electromagnetic devices may cause interference to servo motors. Attempt to isolate or remove sources of interference.

2、 Corresponding adjustment methods:

1. Check and adjust the mechanical structure: Ensure that all mechanical connections are stable and the transmission components are in good condition.

2. Power and signal line processing: Use a regulated power supply to ensure that the power and signal lines are away from interference sources, and use shielded wires to reduce interference.

3. Parameter adjustment: According to the manual of the servo motor or the manufacturer's recommendations, gradually adjust the PID parameters and observe the effect until the optimal setting is found.

4. Testing and validation: Conduct testing to verify effectiveness after adjusting any parameters or changing settings.

There are many reasons for servo motor vibration, such as inappropriate gain setting, mechanical resonance, encoder failure, improper motor selection, and so on. To solve this problem, we need to first identify the specific cause and then prescribe the right medicine.
