10.6 End Vibration Suppression
Figure below, due to the long length of the end of the mechanical load, it is easy to generate low-
frequency vibration during operation and stop. This vibration is often low in frequency, generally
within 100Hz, but it will a󰀨ect the positioning accuracy and settling time of the end.
Vibration at the end
The use of end vibration suppression can better suppress such vibrations, thereby improving the
positioning accuracy of the mechanical system and shortening the positioning and settling time.
Instructions to implement end vibration suppression
Step 1: Analyze Frequency
Use the oscilloRange function of Luna software to observe the curves of " target speed " and "
position error " during the motor stop phase.
Using the gure below as an example, analyze the frequency of position error uctuations after the
target speed is zero.
