Step 7. Enlarge the low-frequency region to observe the maximum amplitude of vibration
frequency, as shown in Fig. 6-42.
Step 8. Enter the value of low-frequency vibration frequency (this example is 6.7 Hz) into
the “Frequency” field in the “VSF” tab of “Advanced gains” window.
Step 9. Check the “enable VSF” option to enable the vibration suppression feature, as
shown in Fig. 6-43. Note that: Do not check or uncheck the “enable VSF” option
during motor motion.
Step 10. After the vibration suppression feature is enabled, it is found from “Scope” that
“Position Error” has become smaller when the motor is stoped, as shown in Fig.
6-44.
