Disabling the Adaptive Filter
The adaptive filter function, which performs automatic tracking in response to the load resonance,
can be disabled by setting the Adaptive Filter Selection (Pn023) to 0. If the adaptive filter is disabled
when it is operating correctly, the resonance that has been suppressed will reappear, and noise or
vibration may occur.
Therefore, before disabling the adaptive filter, perform copying function to the Notch Filter 1
Frequency (Pn01D) of the Adaptive Filter Table Number Display (Pn02F) or manually set the Notch
Filter 1 Frequency (Pn01D) based on the Adaptive Filter Table Number Display (Pn02F) in the
following tables.
Set the Notch Filter 1 Frequency (Pn01D) to 1,500 when disabling the adaptive filter using the above
table.
