Figure 8-30 No vibration suppression, long settling time
Figure 8-31 Settling time - without anti-vibration tuning
In order to suppress oscillations and shorten settling time, the following parameters need to
be set:
⚫ NLANTIVIBHZ2=14Hz, measure the resonance frequency.
⚫ NLANTIVIBSHARP2=0.5, estimate the width based on the sharpness shown in the FFT
tracking.
⚫ NLANTIVIBGAIN2=8, determined by manually increasing the value from 0 until the
optimal settling time is reached.
Figure 8-32 Using vibration suppression tuning - position error and current oscillation are reduced
Figure 8-33 Using vibration suppression tuning - settling time is short
