774 774  * If no measuring equipment, the user can also read the position deviation waveform to confirm the vibration frequency through the "waveform" function of the PC debugging software.
775 775  * Low-frequency vibration detection needs to be coordinated by the two parameters of completion positioning threshold and vibration detection amplitude. When the vibration amplitude is greater than (P5-12*P4-14 detection amplitude ratio), the low-frequency vibration frequency can be recognized and updated to U0-16 monitoring quantity. For example, when the vibration amplitude is greater than (P5-12*P4-14*0.001) detection amplitude ratio. For example, in P05-12=800, P04_14=50, the vibration amplitude is greater than P5-12*P4-14*0.001=800*50*0.001=40 pulses, stop vibration frequency can be identified in U0-16.

838 -* Set P4-22 damping gain, gradually increasing from 0, each time increasing about 20.
839 -* Observe the size of the vibration speed component, if the amplitude speed component is getting larger, it can be the vibration frequency setting error, if the vibration speed component is getting smaller, it means the vibration is gradually suppressed.
