Tips: Causes of vibration failure in AC servo spindle motor.

1. Load inertia. The setting of load inertia is generally related to the size of the load. Excessive load inertia parameters will cause the system to vibrate. Generally, the AC servo spindle motor can automatically measure the load inertia of the system.
2. Speed proportional gain. The larger the setting value, the higher the gain and the greater the rigidity of the system. The parameter value is determined according to the specific servo drive model and load condition. Generally, the greater the load inertia, the greater the set value. When the system does not produce vibration, the set value should be as large as possible. But the larger the gain, the smaller the deviation, the more easily the AC servo spindle motor will vibrate.
3. Speed integral constant. Generally, the greater the load inertia, the greater the set value. When the system does not produce vibration, the set value should be as small as possible. However, reducing the integral gain will slow the response of the AC servo spindle motor and deteriorate the rigidity.
4. Position proportional gain. The larger the setting value, the higher the gain and the greater the stiffness. Under the same frequency command pulse condition, the smaller the position lag, the too large the value may cause the AC servo spindle motor to vibrate.
5. Acceleration feedback gain. When the AC servo spindle motor is not rotating, a small offset will be amplified by the proportional gain of the speed loop. The speed feedback generates the corresponding torque, which makes the AC servo spindle motor jitter back and forth.
