In daily life, when we use a vertical machining center, what conditions can cause the servo motor to vibrate, and how can we solve them? The machine tool editor analyzed the issue of servo motor vibration. When the servo motor vibrates at zero speed, the gain should be set high to reduce the gain value. If the alarm stops due to a slight vibration during startup, it may be due to incorrect motor phase sequence.
When the PID gain adjustment is too large, it can easily cause motor chatter, especially when D is added, which is particularly severe. Therefore, try to increase P and reduce I as much as possible, and try not to add D. Even if the encoder wiring is connected incorrectly, chatter may occur. Excessive load inertia, replace motor and driver. The disturbance of the analog input port causes vibration, and a magnetic ring is added to the motor input line and the servo driver power input line to keep the signal line away from the power line.
There is also a type of rotary encoder interface motor, which can easily cause a sensation due to poor grounding. Vertical machining center servo wiring: use standard power cables, encoder cables, control cables, and check if the cables are damaged; Check if there are any disturbance sources near the control line, and if they are parallel or too close to the adjacent high current power cables.
Check if there is any change in the potential of the grounding terminal to ensure good grounding. Servo parameters: The servo gain setting is too large, it is recommended to manually or actively adjust the servo parameters from scratch; Confirm the setting of the speed response filter time constant, with an initial value of 0. You can test increasing the set value. The electronic gear ratio setting is too large, it is recommended to recover to the factory settings.
