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 (Pn23) to 0. If the adaptive filter is disabled
when it is correctly operating, suppressed resonance will become apparent, and noise or vibration
may occur. Therefore, before disabling the adaptive filter, perform copying function to the Notch
Filter 1 Frequency (Pn1D) of the Adaptive Filter Table Number Display (Pn2F) from the Fit Gain
Window on the front panel (refer to Front Panel Display Example on page 7-9) or manually set the
Notch Filter 1 Frequency (Pn1D) based on the Adaptive Filter Table Number Display (Pn2F) in the
following tables.
• Set the Notch Filter 1 Frequency (Pn1D) to 1,500 when disabling the adaptive filter using the above table.
