Adaptive Filter
Using speed feedback signals, the adaptive filter provides real-time analyses of the vibration frequency
generated from the load during drive operation, and configures the notch filter automatically to reduce
vibration.
It can detect vibration frequencies through frequency analysis in order to automatically configure one or
two notch filters. Here, the frequencies and their widths are automatically set and the setting values for
the depths are used unchanged.

Only one adaptive filter is used. You can check the settings
configured automatically in the notch filter 3 settings (0x2507,
0x2508, 0x2509).
If an arbitrary value is set in notch filter 3, auto setting is not
available. If you wish to use auto setting, you should initialize notch
filter 3 first.

Two adaptive filters are used. You can check the settings
configured automatically in the notch filter 3 (0x2507, 0x2508,
0x2509) and filter 4 settings (0x250A, 0x250B, 0x250C).
If an arbitrary value is set for notch filter 3 (or 4), auto setting is
applied to notch filter 4 (or 3). If arbitrary values are set for notch
filter 3 and 4, the original settings remain unchanged. If notch filter 3
and 4 are initialized, auto setting is available.
